Toyota Camry Check Engine Light: Causes, Codes, Reset & Fixes

We pulled every owner complaint NHTSA has on file for the Camry and Camry Hybrid, model years 2000 through 2025. That’s 15,409 complaints. Of those, 489 mention the check engine light, and they are not spread evenly. Two eras stand out. The 2018–2020 cars carry a long list of fuel pump and engine recalls. The 2007 car, along with some 2008s and 2009s, draws reports of oil consumption.

So start with your model year instead of a generic list of causes. Find it in the table, then go to that section.

One note on the light itself. Steady means a stored fault: drive gently and get it scanned within days. Flashing means an active misfire, so stop and read the flashing-light page.

Light complaints by model year

Read the last two columns together. The decade from 2008 to 2017 produced fewer light complaints than the three model years after it. These are owner reports that NHTSA has not verified, and a count is not a failure rate: more cars sold and more years on the road both mean more complaints.

2018–2020: run the VIN before you pay for a diagnosis

This is where the Camry file looks different. Here, 130 of 1,469 complaints mention the light, the highest share of any period in the table. Owners write about rough shifts, stalling, hesitation, overheating and fuel pumps, and several of those line up with recalls already on NHTSA’s books.

The fuel pump records say “the low-pressure fuel pump inside the fuel tank may fail” and the engine can stall. They don’t say the check engine light comes on, and we won’t claim it does. Owners report it anyway. In ODI 11751447, a 2019 owner wrote that the “check engine and ICS sensor lights came on” and that their own diagnostic pointed to a failing fuel pump, yet the VIN wasn’t on the recall list. Coverage goes by VIN, not by model year, so the only way to know is to look yours up. Look again if your last check was a while ago: 25V-028 was only filed in January 2025. Covered cars get the pump replaced free.

The engine recalls are VIN-specific too. Dealers replace the engine on affected 18V-200 cars, and inspect or replace it under 20V-064. None of those records mentions the light either. They belong on this list because they sit on these model years, and one VIN check catches all of them.

Coolant bypass valve. Ten complaints from 2018–2020 owners name the engine coolant bypass valve, three each from 2018 and 2019 and four from 2020, and the light was on in every one. ODI 11736404, a 2019, says it in one line: “Engine Coolant bypass Valve B control circuit high check engine light.” ODI 11689498, a 2018, says the car was “taken in for a flow shut off valve issue (customer support program).” NHTSA has no recall for it on the Camry, but Toyota Customer Support Program 24TE04 covers a coolant leak from the valve on certain 2018–2021 Camry and Camry Hybrid models. The repair is a new “water by-pass hose,” covered for 10 years from first use or 100,000 miles, whichever comes first, if the dealer confirms the condition; the stretch with no mileage limit ended November 30, 2025. Toyota’s service bulletin T-SB-0112-24, for an “Engine Maintenance Required” message with codes P268111 and P268115, tells dealers to refer to 24TE04 for warranty. The tie to the check engine light comes from owners, though: Toyota’s documents describe a coolant leak and that message, not the light. Ask a Toyota dealer to check your VIN against 24TE04.

Electric water pump on the 2018. Five complaints that mention the light name code P26CB, and all five are 2018 Camrys. Toyota wrote a service bulletin for it in December 2017, T-SB-0323-17: “Some 2018 model year Camry vehicles equipped with four-cylinder engines may exhibit a MIL ‘ON’ condition with Diagnostic Trouble Code (DTC) P26CB71 (Electric Water Pump Speed Stuck).” Its fix is modified engine computer logic. Toyota’s technical tip T-TT-0614-20 covers the same code on 2020 models with the 2.5L A25A engine, with the light, a coolant leak from the electric water pump, or both. The owners’ stories point at the pump. ODI 11703097 records “P26CB71 – Electric Water Pump Speed Stuck” with the pump actuator “mechanically stuck.” In ODI 11681883 the light came on, then a “Coolant Temp High” message; the coolant was gone and the water pump had failed. That’s the gap to keep in mind: the bulletin’s fix is modified ECM logic, while these owners report the pump itself failing.

Another Toyota bulletin, T-SB-0010-24, covers 2018–2024 Camrys that turn on the light with misfire codes P0300 to P0304 “upon cold soak start up with engine coolant temperatures between 14°F – 41°F.” Bulletins like these are repair instructions for technicians, not recalls. They don’t make a repair free; that happens only under warranty or a Toyota program.

Camry Hybrid: a recall the light won’t show. Toyota’s voluntary emission recall 26TF01, filed with the EPA and CARB on August 6, 2026, covers certain 2018–2024 Camry Hybrids, about 227,500 of them. Toyota’s notice says: “Under certain conditions, debris can accumulate inside the fuel cap causing potential fuel vapor leaks that can cause increased evaporative emissions to exceed the regulated limits. This issue will not trigger the M.I.L.” The remedy is free: the dealer replaces the fuel filler dust shield, and on some cars the fuel cap too. Toyota is phasing it in by model year: August 6, 2026 for 2018–2019 cars, September 10, 2026 for 2020–2021, November 2026 for 2022–2023 and December 2026 for 2024. No light will point you to this one, so ask a Toyota dealer to check your VIN against 26TF01.

Transmissions that didn’t warn. ODI 11727746 describes a 2019 slipping gears, shifting hard and getting stuck in gear. Another 2019 owner says no check engine light or other warning came on before the transmission failed (ODI 11712582). So the light is not a guaranteed early warning. A Camry that starts shifting badly deserves a look with or without it.

2007–2009: the oil burners

Oil consumption or burning oil comes up in 27 light complaints. Fourteen of them are 2007 cars, and most of the rest are 2008s and 2009s. In ODI 11315553, a 2007 owner describes heavy oil burning, then the light with a “cylinder 3 misfire” and a bad spark plug.

If that sounds like your car, look at the dipstick before you buy ignition parts, and start writing down how much oil goes in between changes. Owners also mention a Toyota oil-consumption test (ODI 11184745) and a Toyota program, and Toyota’s own bulletin confirms the program. Warranty Enhancement Program ZE7 (Warranty Policy Bulletin POL14-12) covered excessive oil consumption on certain 2007–2009 Camry and 2007–2011 Camry Hybrid models. Eligibility depended on an oil consumption test done by the dealer, following service bulletin T-SB-0158-14. Coverage ran until October 31, 2016 regardless of mileage, then 10 years from first use or 150,000 miles, whichever came first, so on these cars it has run out.

2000–2006: hesitation first

The 2000–2006 cars logged 157 light complaints out of 4,138. Two groups lead, close to even: hesitation or a throttle that doesn’t answer, and stalls. Then come catalytic converter and oxygen sensor complaints, then EVAP and gas cap ones. ODI 10543787, a 2005, is a clean example of the first kind: the light came on pulling away from a stop, the car didn’t respond to the throttle, and after a restart it ran normally.

Scan a car like that even if it seems fine afterward. The stored code may be the only record left of what happened.

On the 2003 Camry, Toyota had a campaign for a fault that looks like this. Special Service Campaign 30I, from July 2003, says: “The throttle body motor may malfunction causing the malfunction indicator light (MIL) to illuminate on the dash, and the engine control module (ECM) will store a trouble code and place the vehicle into a limp home mode.” The remedy was to “inspect and/or replace the throttle body.” One 2003 owner told NHTSA about a “defective throttle body… the check engine light appears and the gas pedal has no effect on the engine” (ODI 10436156). That was free campaign work, but it dates from 2003, so ask a Toyota dealer whether your VIN shows 30I as done before you pay for a throttle body.

Wrong light: the 2004–2005 V6 pulley recall

Recall 11V-539 covers 2004–2005 Camrys with the 1MZ-FE or 3MZ-FE V6, built June 2004 through March 2005. NHTSA’s text says the crankshaft pulley problem can cause noise and/or the battery discharge light. It doesn’t involve the check engine light. If the symbol on your 2004–2005 V6 is the battery, start with that recall.

2021–2025 and the newest Camry Hybrid

Only 9 of 515 complaints on these years mention the light, too few to call a pattern. One recall is still worth a VIN check on the newest cars. Recall 25V-869 covers the 2025–2026 Camry Hybrid: a bolt inside the inverter may not be tightened properly, which can mean a loss of motive power or a short. Dealers replace the inverter assembly free.

Codes owners wrote down

A dash means we haven’t sourced an official definition, so we don’t print one. Counts this small are a record of what owners typed into their complaints, not a ranking of what breaks. Fuller definitions for the common Toyota codes are in the Toyota code reference.

Emissions warranty on a newer Camry

Before paying for a catalytic converter or an engine computer, check age and mileage. EPA’s emissions warranty rules cover the catalytic converter, the electronic emissions control unit (ECU) and the onboard emissions diagnostic device for 8 years or 80,000 miles. Other emission-related parts get 2 years or 24,000 miles. Defects in materials or workmanship inside those limits are repaired free. On a Camry still inside 8 years and 80,000 miles, a code pointing at the converter or the computer may be a warranty claim rather than a bill.

Before anyone clears the code

Run the VIN at nhtsa.gov/recalls. Recall repairs are free, and on a 2018–2020 car that one lookup covers every campaign in the table above. Then get the code read and keep the exact wording. Clear it only after the repair; the reset guide walks through the methods. If VSC or TRAC OFF came on at the same moment, see TRAC OFF with the check engine light first.

How we built this

Complaints come from NHTSA’s Office of Defects Investigation database, pulled through api.nhtsa.gov (complaintsByVehicle) on 2026-10-16 for model years 2000 to 2025, Camry and Camry Hybrid combined, plus the records NHTSA files under “Camry HV” (most 2014 Camry complaints sit there), de-duplicated by ODI number. The Camry Solara is a separate model and is not counted. 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. Recall details are NHTSA’s official recall records from the same API. Toyota’s service bulletins and program letters are quoted from the copies Toyota filed with NHTSA, kept in NHTSA’s manufacturer communications file. Our model-by-model study uses a different window, model years 2012 to 2023, scaled by sales, so its Camry figures won’t match these. The two answer different questions.
