Check engine light and traction light went on

Asked by Oct 17, 2016 at 09:35 PM about the 2010 Toyota Camry LE

Question type: Maintenance & Repair

The check engine light and traction light went on simultaneously. Dealer found fault codes 1201 and 1231. He said we need charcoal canister replaced and new steering angle sensor (around $1,200). I'm skeptical from what I've been reading online. Thoughts on what else it could be or how to confirm that these are actually needed??

Your skepticism is well founded. There is a Toyota Technical Service Bulletin which addresses the C1231 code in your vehicles computer. The C1201 is a Steering Angle Sensor Code. Based on your description and concern...I see no connection with the Charcoal Canister. You might consider a second opinion from another Toyota Dealer. The Steering Angle sensor may only need to be RESET. The TSB is most likely a "reflash" of the ABSTC Computer. Ask the Dealer what it would cost to perform TSB 0086-12 which address the c1231. Get as much detail about the repairs as possible and get back to us. Knowledge is Power.


BTW...what Engine and mileage for this vehicle.

Thanks for your reponse. We have about 73,000 miles and not sure the engine type. We brought it to a mechanic this morning who reset the.lights and they came on again. He said he could smoke out the emission line to see if there is a leak. That was what he thought the problem was but that test will cost about $100 before any repairs are made...

(from OaklandNJGregory) The only engine information I have been able to find for our 2010 Camry LE is '2.5 liter'. I hope that helps.


Your mechanic should be able to look up that TSB in his computer to see if it applies to your CEL/TCS codes and concerns. As far as that "smoke" test/procedure is appears there IS and issue with the EVAP System. So...I assume there must be another Code...other than the C1201 and C1231 set in the Computer.


Update....slight typo error....That Toyota TSB is...TSB-0086-13. Good luck.


Oakland...any update on the issue with this vehicle?
