#1 of 13 check engine light on by chasiaw Oct 15, 2008 (6:57 am)
I have a 2002 RAV 4 with 75,000 on it. The check engine light suddenly went on this morning. I have not gone to the dealer yet as it will be expensive to do so. I have an extended warranty but am not sure if they will cover the cost. As to the problem, is there a quick fix to this? Can I just do it myself?

Replying to: chasiaw (Oct 15, 2008 6:57 am) You need to find out why the warning light is coming on. Ignoring it can be very costly in the end.   tidester, host SUVs and Smart Shopper Replies to this message: chasiaw (Oct 16, 2008 5:50 am) tidester (Oct 16, 2008 10:11 am) chasiaw (Oct 16, 2008 12:51 pm)

Replying to: tidester (Oct 15, 2008 10:02 am) Thanks for the reply. I went to AutoZone yesterday and had a diagnostic check made, the code that was given was P0442 which says that it has an air leak. The guy at AutoZone told me that usually, it is from the gas cap. The cap is in tip top condition. Would you know anywhere else it can come from? If I remove the connection on the battery, will it help in resetting the light to turn off? Replies to this message: tidester (Oct 16, 2008 10:11 am) chasiaw (Oct 16, 2008 12:51 pm)

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)

Replying to: tidester (Oct 16, 2008 10:11 am) Thanks for the help. I just hope that there will be no drastic effect to the car's engine if I use it. Thanks again.
#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.
