jenshi: It is true--most parts for a Toyota must be bought from the dealer. However, my mechanic gets the oil filter for my 06 Avy Ltd for $6----not sure from where--Don't ask--Don't Tell!! Call Pep Boys/Firestone--you know what needs to be done--they can at least give you a quote. I'd probably go to the dealer--only 5 blocks away--also,, ya know he's close if it ain't fixed right!! I've been very fortunate to locate an HONEST mechanic--fair pricing and if i need "emergncy" work--because he services my Avy and wife's Jeep, we get priorty attention. Good luck and let us know the results!

i went to the another store to diagonose my car. the guy just help me to shut off the three lights. he said, the lights may or may not comes back,if come back, he will repair it. he think it is the TPS -truck control sensor is bad. and i asked him to write down the trouble code for me, a lot of trouble codes: p0172, p0120,p0121,p0715 and p1128. obviously, i went to two stores and got the different results. the first one only said the trouble code was p0171, nothing else. i don't know who i should trust. the second one also suggested me do a lot of turn-up:
1, spurk plugs 2, wires, 3,air filter,4 gas filter,5 pcv valve 6,clean the trotle. i just let him replace the air filter, others i am not sure whether should do or not. i know most of techinicians let ur replace here and replace there.
here i need ur help:
1.what all these trouble code mean,p0172, p0120,p0121,p0715 and p1128?
2. how much is the TPS -truck control?
3. should i just follow them to do what they suggest me?
sign, my car didn't get repaired, but i already spend $80 for the two diagonosis.
your inputs is very important to me, thanks.

the TPS is the throttle position sensor. it tells the engine control unit (ECU) how much air (and thus fuel) is being commanded for the engine because the TPS measures the position of the throttle valve.
cars are supposed to run to a specific Fuel/Air ratio. the throttle is the valve that lets the engine suck more or less air comming from the air intake and filter.
your car's engine is essentially an air pump. it does it's work based on the compression and expansion of that air (in unison with fuel and spark) to mechanically move the pistons and apply torque to the drive train connected to the engine.
When the throttle valve commands more air, the vehicle needs to add more fuel via the injectors to keep the F/A ratio within certain limits, but also to add power.
for the trouble codes, why don't you google each one of them? you can do it.

jenshi: Stop wasting your time and go to a Toyota dealer--must be one or two in your area. They (should) know the car and early Avalon's were fairly bulletproof cars. Good luck!

I am actually having this problem right now with my 2002 XLS. It just started yesterday and is irritating me. A lot.
All of the electrical systems work fine. I can turn on the headlights and play the radio etc., but when I turn on the ignition, everything dies. If I open the hood, then shut it again, the lights come back on. Sometimes, the car will start and be fine. Sometimes the dashboard doesn't work at all but the climate control and radio will work. It seems that there is some issue with the engine immobilizer. Could this be an issue with a fuse or is the compter going wonky?

It sounds very much like you have corroded terminals in either your battery or the cables and clamps connecting them. Check them out thoroughly, I'll bet you dollars to doughnuts that this is the case. Once you find the corroded terminal(s), your problem should be solved.

I checked the termninals and the cables and there isn't any corrosion. I started the car last afternoon about 15 times in a row and it started fine and all of the systems were working. However the dashboard data was all reset (January 1st, compass pointing the wrong direction, etc...).
I guess it's time to take it in. Thanks for your help.

My mother had this same problem with her 99 Avalon XLS. In Canada they came with automatic headlights. It says in her owners manual to turn the headlights to the off position, as to extend battery life, as the sensor can drain power when the car is off. On a side note in her case it turned to be that the keyfob is open the trunk after a very light press. (future Avalons require you to hold the trunk open option for several seconds) The light in the trunk is a simple loop from battery to trunk switch to trunk lamp to ground, with no light in the dash to indicate its opening. The lamps draws alot of power and caused her to run down 3 batterys before I trouble shot the problem. (we live 2000km apart) Installed an LED trunk light that drew less power and her problems were solved($12.00). Also if you find that that helps I can provide info to install an inline LED to the trunk lamp circuit so it lights up in the dash cluster to indicate the trunk is open.
Sorry for the winded reply,

the three light was turned down two month ago, now three light is on again. so i have to repair it at no choice. today i went to the dealer first, i just want to know the retailer price. the guy told me the TPS is THROTTLE POSITION SENSOR $75, and not the technician said truck control sensor, but the technician told me TPS will cost around $400. so i want to know does anybody here know about truck control sensor, or the technician gave me the wrong name? and does someone here know how much the TPS, I just want to make sure the guy gave me the right price for my 2000 avalon. thanks a lot.
