#10 of 71 Check engine with VSC & 4WD lights on
Mar 31, 2009 (11:49 am)
Last month, my 2007 Rav4 V6 Ltd showed the check engine, vsc & 4wd lights on. Went to my Toyota dealership immediately as requested. Cause: codes P0302 & P0304. 2 coils #2 & #4 misfiring, ordered and changed. 4 weeks later, same lights on and vehicle running rough. Back to dealership and cause was: codes P0300P0302/P0304/P0306 RE TSB2964 oil control valve bank 2. Intake & exhaust oil control valve changed. Now, 6 weeks later, same lights again! Code P0456. Evap control system leak. Cleaned loose fuel cap and tightened & resecured hose in clamp at fresh air box. Now all seems good and hopefully fixed the problem. All under warranty so happy. I had read this morning on your site about the gas cap and there you have it. Thank you. Hope this will help Rav4 owners with similar problems.

#12 of 71 CEL VSC 4wd gas cap
Jun 28, 2009 (7:59 am)
I recently had the CEL come on (and a few seconds later the VSC and the 4wd light come on, which on another forum someone wrote that the CEL disables the VSc which disables the 4wd. Also as noted in another forum, this disable the cruise control). The gas cap was not fully tight, but I had had 140 miles since my last fill up (however, I was above 7,000 feet which seems to improve my mileage a lot but also meant a dealer was far away). Tightened the gas cap and 200 miles later the lights went off. The guys at autozone were great as it did say EVAP leak (and a sensor error) and they offered to disconnect my battery to reset it. The autozone guy thought it might take 30 short drives to reset the light. Thanks for the advice here!

This text follow my message on march 31, 2009
The toyota dealer received my parts, I went to the dealer to replace the oxygen sensor located near to the cathalytic exaust system (there is four sensors on the catalytic exaust system, two up front and two at the back for a six cylinders engines)
So for the replcement of that oxygen sensor the dealer report me that during the installation they find the sensor wires were cutted (broken)....I beleived the original sensor was good....dealers dont spend enough time to find the problem and make the wrong diagnostic. But the 250.00$ sensor was on waranty...so they installed that new oxygen sensor and they repaired the broken wires and so far so good...no message anymore and the car running perfectly. I love that car amazing drive.

Rav4 2007 - All those 3 lights "on" again.
I went to the dealer today and they said its the oxygen sensors again but not the same they changed ! two others. They said it will cost me for one sensor between $400 to $600 it depend if they have to re doing the thred because the sensor are jamed. Also they said the fact that they have two error codes one for each sensor , if I change one sensor I may have the lights on again so I will have to replaced the second one, or , I changed both at the same time for the price between $800 to $1100. I said NO I take my car back and I will think about it. I told them this is no sense , these sensors are made to detect air exaust problems and I dont have any problem with air exaust I have big problem with these sensors !!! I am replacing these sensors every 7 months !!!
I take my car back tomorrow and I will see...I think TOYOTA have serious problem with these sensors and I dont have to pay for that !
Will see tomorrow.

They all came on at the same time just this early morning. The manual says take the car to the dealer. In reading everyone's posting, it sounds like sensor problem which may or may not be covered by warranty anymore. When I wake up this morning, I will check the gas cap, clean it up and make sure it is secured. This cap for me really has never been secured. It does not click when I close it. If everything else fails, I will bring it to the dealer and will get back here for the result. In the meantime, if anyone has better news for me, please help!
#16 of 71 2006 Rav4 Check engine light P0606
Mar 09, 2010 (3:24 am)
I have 114,000 miles on my RAV and my check engine light has come on. The code is an ECM error. Timing was close to getting a new set of tires at one store and oil change at my dealership. Could they have done something? Any ideas or is it going to be a really expensive ECM replacement?

First make sure your gas cap is secure.
Second, take your time before making any replacement by any garage or dealer. Most of the time you can drive months with these lights on. Maybe you will consume more gas but thats it. Nothing bad will happen to your engine.
Then you can ask questions to your dealer or other toyota dealer and see what they proposed and ask an estimated on paper. Take your time dont rush. Ask questions to others.
It is probably the oxy sensor...they cost alot...

If you have an Autozone close by they usually scan and diagnose for free (hoping you'll buy the replacement parts from them, but there is no obligation) I know this is true for OBD-II scanning and not sure beyond that.

Following my message on Jan 12, 2010 and for all the peoples who have the same problems...
After battleling months with toyota canada customer service, toyota concluded to pay for the estimated repair $250 and the dealer $150. So after all this battleling and driving three months with all 3 check engines lights on, I send my car for repair to the dealer.
I got my car repaired this week April 23, 2010. They replaced two oxygen sensors.
They told me the computer recorded warnings history on two oxygen sensors for three mounths and they decided to replaced those two oxy sensors.
I had to pay for this repair $550.00 can (included tax) instead of $900.00.
The dealer told me they did not charge the computer check fees, they lower the cost of those sensors and cut down the time labor to 1.8hrs
I hope the oxygen sensors will last longer then the original ones....
