Replying to: chasiaw (Oct 16, 2008 5:50 am) That code indicates that there is a leak somewhere in the evaporative control system with the gas cap being the most likely place for that to happen. However, it can be anywhere within the EVAP control system such as one of the hoses. Perhaps someone with RAV4 experience would tell us how to reset the light - anyone?   tidester, host SUVs and Smart Shopper Replies to this message: chasiaw (Oct 16, 2008 12:51 pm)

#6 of 13 VSC TRAC Light on and off at random intervals by jsdavis7 Feb 21, 2009 (9:41 pm)
I have a 2004 RAV4 where the VSC TRAC warning light will come on while driving, and will go out after some time has passed, but no definite interval. The TRAC OFF light and Check Engine light also come on, and go off at the same time. No constant interval between time on and time off, nor between time off and time on. My mechanic thinks it might be a sensor, or a loose connection from a collision. Any other ideas? Replies to this message: tidester (Feb 21, 2009 10:40 pm)

Replying to: jsdavis7 (Feb 21, 2009 9:41 pm) A problem with a sensor or loose connection (from whatever cause) seem probable or it could some electronic control module. Anyone else have ideas?   tidester, host SUVs and Smart Shopper
#8 of 13 2002 Rav4 Check engine light by ginger_girl Mar 03, 2009 (6:51 am)
My check engine light recently came on and I went to Auto Zone for a reading. They said it was the "temperature control sensor", which, after asking at a few repair shops found that this term/piece does not exist in a 2002 Rav4. They said it could be 2 other things that are closely related to that term (having to do with temp control) and would be around $200.00 to fix, and if not done soon could lead to greater engine problems ranging in the $2-3,000 range to fix. ICK! Anyone know of anything about this?? Replies to this message: tidester (Mar 03, 2009 8:33 am)

Replying to: ginger_girl (Mar 03, 2009 6:51 am) Could they be referring to an Intake Air Temperature (IAT) sensor? It measures the temperature of the air going into the engine and is used to adjust the fuel mixture. Does that $200 include installation?   tidester, host SUVs and Smart Shopper
#10 of 13 Check engine with VSC & 4WD lights on by rav4u2 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 13 CEL VSC 4wd gas cap by hubrist 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!

Replying to: fredy3 (Mar 31, 2009 11:20 pm) 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. fredy3
