Toyota RAV4 Check Engine Light: Causes, Codes & Fixes

What a lit check engine light means on a RAV4 depends on the model year. On certain 2001–2003 models, Toyota itself traced a set of transmission codes to the engine computer. On 2006–2012 models the light often arrives with VSC or TRAC OFF, and sometimes 4WD too. On 2019–2021 models, owners tie it to a coolant valve whose leaks Toyota covers under a support program. We built this from NHTSA’s records: 9,501 owner complaints for 2000–2025 RAV4s, 443 of them mentioning the light, plus Toyota’s own bulletins and owner letters on file there.

A steady light is a stored fault to get scanned soon. A blinking light means an active misfire, which has its own page.

The complaint file, by model year

Two limits apply. These are owners’ own accounts, which NHTSA doesn’t verify. And a count isn’t a failure rate: generations that sold more, or that have been on the road longer, collect more complaints of every kind. Our check engine light by model study uses a different window (model years 2012–2023, scaled by sales), so its RAV4 figures won’t match these.

One distinction before the Toyota paperwork. A technical service bulletin (TSB) is a repair instruction for technicians. It isn’t a recall, and it doesn’t make a repair free; the work is paid only under warranty or a Toyota program.

2001–2003: Toyota traced it to the engine computer

In 2010 Toyota wrote to owners of certain 2001–2003 RAV4s with an automatic transaxle about Customer Support Program ZTL. The letter names the light outright: these vehicles “may exhibit a harsh shift condition and/or Malfunction Indicator Light (check engine light) ‘ON’ condition,” with codes P0750, P0753, P0755, P0758 or P1760. The cause, in Toyota’s words: “Solder located in one of the electric circuits of the Engine Control Module (ECM) may peel over time. This is the major contributor for this condition.”

About 235,500 RAV4s produced from July 2000 to July 2003 were covered. The repair was a new ECM, or an ECM plus the automatic transaxle, and “In the majority of cases, the repair will only require the replacement of the ECM.” Coverage ran 10 years or 150,000 miles from the in-service date, whichever came first. Ten years have now passed for every 2001–2003 RAV4, so it has run out, but the letter still tells an owner what the fault usually is.

The complaints match. For 2001–2003, 174 of 1,153 mention the light, against 23 of 295 for 2004–2005. P0755 is written into three of them, all on 2001–2002 models. One 2001 owner with hard shifts found Toyota’s 2006 bulletin on these codes, TC002-06 (since superseded by TSB-0156-10), and reports that “our ECM did need to be replaced” (ODI 10233815). Two other 2001 owners were told it was the gas cap; the dealer turned the light off, and it was back “within a couple of weeks” (ODI 10344668) or “within 2 days” (ODI 10316443). A 2002 owner heard about “a factory warranty extension for the ECU,” but with the light off, the dealer said “they cannot get any codes” (ODI 10455280). The lesson for an old RAV4: write the code down before anyone clears it.

2006–2012: three lights at once

Of the 3,562 complaints for these years, 116 mention the light; for 2006–2008 alone it’s 84 of 2,282. In 49 of the 116 the owner also mentions VSC, TRAC or traction control, and 29 of those 49 add the 4WD or AWD light.

“CEL, 4WD, TRAC OFF all three lights came on,” a 2011 owner writes; the rear oxygen sensor was blamed and replaced twice (ODI 11064498). A 2008 owner with the check engine, VSC and 4WD lights was advised to disconnect the battery to reset them: “it worked until car was shut off. Then the lights came on again” (ODI 10621846). Our TRAC OFF and VSC guide explains how one engine fault can switch the stability aids off, and TRAC OFF and the check engine light on a RAV4 covers this model. Until it’s sorted, take wet or snowy roads gently.

We don’t know which code the 2011 owner had. For some 2009–2012 RAV4s with the 2AR-FE engine (non-PZEV), though, Toyota’s T-SB-0151-18 describes “a MIL ON condition with DTC P0138 (Oxygen Sensor Circuit High Voltage [Bank 1 Sensor 2])” that “may be caused by incorrect air fuel ratio sensor response.” Its fix is modified ECM logic, a software update, not automatically a new rear sensor.

Oil consumption, 2006–2008. Toyota’s Warranty Enhancement Program ZE7 (Warranty Policy Bulletin POL14-12, December 16, 2014) covered excessive engine oil consumption on certain 2006–2008 RAV4s with the 2AZ engine. Eligibility depended on a dealer-performed oil consumption test, set out in TSB T-SB-0158-14: “The piston assembly has been changed to minimize oil consumption.” Primary coverage ran until October 31, 2016, regardless of mileage, then 10 years from the date of first use or 150,000 miles, whichever came first. For a 2006–2008 RAV4, that has run out.

The program doesn’t mention the check engine light, but owners connect the two. Reading the 2006–2008 complaints by hand, we found 15 where the light came on and the engine was burning oil or found low (four from 2006, seven from 2007, four from 2008). A 2008 owner reports “excessive oil consumption. Engine light kept going on,” and the engine failed the dealer’s test (ODI 11130523). Another says that every 1,400–2,000 miles the light comes on and the oil is two quarts low, with no leaks (ODI 10654627).

One more bulletin names the light: TSB-0046-10 covers 2006–2010 RAV4s with “MIL ON; fuel in EVAP system” and P043E, P043F, P2401 or P2419.

2013–2018: the quiet stretch

Only 28 of 1,697 complaints for these years mention the light, and no RAV4 recall from this window names it. The one Toyota bulletin to know is for the hybrid: T-SB-0079-19 says some 2016–2018 RAV4 Hybrids “may exhibit a hybrid system warning message/MIL ON condition with DTC P0A45 (Drive Motor ‘B’ Position Sensor Circuit).“

2019–2025: valves, pumps and cold starts

The current RAV4 (2.5L A25A engine, plus Hybrid and Prime) has 101 light complaints out of 2,764. The 2019 model year alone has 36 of 901.

The coolant bypass valve and program 24TE04. Toyota Customer Support Program 24TE04, “Coverage for Flow Shut-off Valve Coolant Leak” (first published December 5, 2024; dealer letter updated 8/11/2026), covers certain 2019–2021 RAV4 and RAV4 Hybrid models, about 925,210 of them, and certain 2021 RAV4 Primes. Toyota describes “a small engine coolant leak that can occur from a specific valve that can allow coolant to drip on other parts of the vehicle. This can cause ‘Engine Maintenance Required’ to be displayed on the instrument cluster or cause the A/C not to function normally.” On the RAV4 the repair is a new “water by-pass hose” assembly, done by a dealer once the condition is verified. Primary coverage ended November 30, 2025. Secondary coverage runs 10 years from the date of first use or 100,000 miles, whichever comes first, so it’s still running for most of these cars.

Toyota’s T-SB-0112-24 (Rev2, June 2025) covers 2018–2021 vehicles with A25A-FKS, A25A-FXS or M20A-FKS engines that show the “Engine Maintenance Required” message along with “DTC(s) P268111 (Engine Coolant Bypass Valve Circuit Short to Ground) and/or P268115 (Engine Coolant Bypass Valve Circuit Short to Battery or Open).” It tells dealers: “Refer to Campaign Publication 24TE04 for warranty applicability.”

Neither document mentions the check engine light. Owners report both. Of the RAV4 light complaints, 24 name the coolant bypass valve (16 from 2019, five from 2020, two from 2021, one from 2022). In 18 the owner says the light came on. In five it did not, and only the message showed. One is unclear. A 2019 owner with the light and P268115 says the dealer told them the program “only covers valves that leak externally, not internal failures” (ODI 11660223). That’s the owner’s account. Toyota’s bulletin for those codes points dealers to 24TE04, so if your 2019–2021 shows P268111, P268115 or the message, ask for a VIN check against 24TE04 and bring the number T-SB-0112-24. The program’s RAV4 list ends at the 2021 model year.

Recalls 20V-064 and 20V-682. Two free recalls cover 2019–2020 RAV4s. Recall 20V-064 (Toyota 20TA04) concerns porosity in the engine castings of 2.5L RAV4 and RAV4 Hybrid models, which can crack and leak coolant: “A coolant leak can cause the engine to overheat and cause a vehicle stall in conventional gasoline vehicles…” Dealers inspect and replace the engine as necessary. The recall text doesn’t mention the light. Recall 20V-682 replaces the fuel pump: “The low-pressure fuel pump inside the fuel tank may fail,” and “the engine can stall while driving.” Owners do report the light with pump failures. One 2020 stalled while fueling, “diagnosed fuel pump” (ODI 11692924); another shut off while driving, “faulty gas pump” (ODI 11533528).

Toyota bulletins for the A25A engine that name the light.

Owners cite them too. A 2022 owner names T-SB-0010-24 with P0303 (ODI 11740904), and a 2019 owner’s electric water pump failed at 64,273 miles with the light on and P26CB (ODI 11764531).

Hybrid and Prime. Hybrid bulletins that name the light include T-SB-0023-20 (2019–2020, inverter over-current codes), TSB002622 (2019–2021, P0AA649 or P1C8049) and TSB-0033-23 (2021–2023 Hybrid and Prime, P24517F). For a 2021 Prime, check recall 23V-041: in certain cold weather in EV Mode, the hybrid control software may shut the hybrid system down if the accelerator is pressed rapidly, and the car stalls. A free software update fixes it.

“Engine stopped, power steering low.” Across all RAV4 complaints, 82 for 2021–2024 models describe an “Engine stopped / power steering low” (or “low power steering”) warning with the engine shutting off. In 47 the owner mentions rain or the wipers, and 21 also mention the check engine light. A 2023 owner in a drive-thru, wipers on intermittent, reports “engine shut off steering power low” with the check engine, battery and steering lights on (ODI 11582816). A 2024 owner’s engine cut off on the highway in pouring rain, with the light and “engine stopped - power steering low” (ODI 11665093). NHTSA’s data shows no recall and no open investigation for it, and we found no Toyota bulletin in NHTSA’s file that describes it. It’s a pattern of owner reports, nothing more.

Recalls that come up on a VIN search but aren’t about this light

Recall 11V-245 (airbag roll sensors, 2007–2008) uses “malfunction indicator light” for the airbag warning light. Recall 25V-595 (2023–2025 RAV4 and RAV4 Prime) covers an instrument panel that may fail to display speed, brake and tire-pressure warnings at startup. Neither concerns the check engine light.

Who pays for the repair

Run the VIN at nhtsa.gov/recalls first; recall work costs the owner nothing. Of Toyota’s programs, ZTL and ZE7 have expired, while the secondary coverage under 24TE04 is still running.

Then there’s the federal emissions warranty. EPA’s question-and-answer sheet lists the catalytic converter, the ECU and the onboard diagnostic device among the specified major emission control parts, covered for 8 years or 80,000 miles. Other emission parts get 2 years or 24,000 miles. On a newer RAV4, a code that points at the catalyst or the engine computer may be a warranty claim, not a bill.

Once the cause is fixed, our reset guide covers clearing the light. The codes Toyotas throw most are in our code list.

How we counted

Complaints come from NHTSA’s public API (complaintsByVehicle), pulled October 16, 2026, for model years 2000–2025, covering the RAV4, RAV4 Hybrid, RAV4 Prime, RAV4 EV and the 2025 RAV4 PHEV. NHTSA returns many complaints under more than one of those names, so we removed duplicates by ODI number. Model and year are read from each complaint’s own vehicle record, so records NHTSA returns for another model or for no model at all are left out. A complaint counts as mentioning the light if the owner’s narrative says “check engine,” “engine light,” “CEL,” “malfunction indicator” or “MIL light,” a rule that also catches owners who write that the light did not come on. We checked the coolant valve and oil consumption counts by hand. Recalls come from the same API (recallsByVehicle). Toyota’s bulletins, program letters and technical tips come from NHTSA’s manufacturer-communications file.
