Question about 2002 Toyota RAV4

1 Answer


I have 75,000 miles in this SUV and I only have this problem this morning. Have not been to the dealer so I don't have a code to share. I have an extended warranty and am not so sure if this problem will be covered. Is there a quick fix? If so, how can I do it?

    Thanks for the reply. I went to AutoZone yesterday and the code given was P0442. We checked the gas cap and it is in good condition. Where else do you think might be the problem? If I remove the connection to the battery, will this help?

  • maschasiaw Oct 16, 2008

    Thanks again for the help and very detailed steps in fixing the problem. I hope that I can fix this with ease. With regards to the TSB, will this help in giving me a discount to the parts? I am also not so sure if my extended warranty is still valid, if so, will they cover this fix?

    My e-mail address is Thanks again for the help.

    I received the TSB. Thanks for the help extended.

    Where can I find exactly the vent tube, right, center or left side of the fuel tank. I am technically challenged. I want to learn how to do it and want to free myself from dealers.

    Hi again:

    I have talked to Toyota Extra Care with regards to my plan and they informed me that it will be covered by it. I was thinking of going to the dealer since one of my passenger windows is not working. They told me that I need a diagnostic check from the dealer itself. I am afraid that the dealer will tell me what they saw is not covered by the plan and then I have to shoulder the diagnostic fee which we all know is ridiculous. How will I let them know that the problem is that of the fuel tank vent hose. Will the bulletin that you faxed me help in this situation? SOS.

Without the code, it is virtually impossible to determine what the problem is, other than you just may have a loose fuel cap. A loose cap will def set the light off. ...Normally, sensors for the engine are usually covered under most extended service contracts, if it is a sensor issue.... Perhaps you could go & find an Autozone near you, they can hook up a scanner & give you the code(s); please get the codes back to me and I will def assist you with your issue!

    Don't bother disconnecting the battery, the ECU will remember the code, and you cannot shut the light off without a proper fix.

    Toyota is aware of a P-0442 issues, and has issued a Technical Service Bulletin regarding this issue; TSB # EG008-02

    What you need to do is:

    Go to a Toyota dealer & order this part:


    This is the fuel vapour vent tube that goes from the fuel tank to the charcoal canister, under the rear of the vehicle. Remove the existing line, and you will find a small cut at the center of the hose; replace it with the new hose. The hose has special ends, and you have to have the right hose for proper hook-ups.

    While you are ordering the part, get the dealer to give you a copy of the TSB. If they will not provide you one, repost with your e-mail, and I will e-mail it to you, or post your e-mail, and I will do it now.

    This should def eliminate your problem.

    The service contracts are varied. I cannot tell you yes or no.

    The TSB will not get you a discount, I'm sorry to say, but, since you have the part number, and the parts guy won't take his time to look it up, maybe he will cut you a break...Let's hope so...

    The TSB is on its way.

    Got your e-mail. Thank you.

    Please remember to rate my level of helpfulness; a "FixYa" would be most appreciated!

  • Toyota Ed Oct 17, 2008

    Thank you for the FixYa! Much appreciated.

    The vent line comes from the top of the tank, the charcoal canister is a rectangulat black box. You are going to need to be under the car to effect this repair.

  • Toyota Ed Oct 20, 2008

    The diagnosis is covered by Toyota Extra Care when there is a failure of covered part.

    The bulletin may help. Wishing you the best.

My2002 toyota tacoma 4 cylinder trucks check engine light went on this morning. Xmas Eve. I have 200,000 miles on it. Can i drive it to my folks house and back home round trip is about 60...

If the light is on steady and not flashing go on ahead and when you get back stop by a parts store and ask if they can read the code and then go from there. When the light is on steady the computer substutes a known good value to keep it running till you can get it in for repairs. But if it flashes while driving that means it has a engine damaging condition going on and sud not be driven.

Transmission just started slipping and clunking at 107,000 miles.

Well, I had the same problem and after changing the good as new looking pink fluid in a " do not change under normal driving conditions" transmission, having the ECM reprogrammed and taking the car by AAMCO transmissions I took a lead and bought an updated and new ECM and had it reprogrammed at the dealer. The shift bucking stopped and as long as you don't see out of the ordinary wear indicated by exessive flakes in the transmission pan the mechanicals of the trans are toyota reliable... it was just a badly designed ECM. I bought my new ECM for $800 online from a toyota car dealer in Virgina.
