3rd & 4th Generation (1992–1996 & 1997–2001)Toyota Camry Discussion for years: 1992-1996 & 1997-2001
Topics of discussion range from fuel economy, safety, modifications, performance all involving America's favorite family car, the Toyota Camry.
Hoping someone can help me out...93 camry LE is having trouble...sometimes it works fine other times it doesn't. Sometimes it will die out upon giving it gas from a stop, other times it will miss throughout the RPM range and rpms will stumble while accelerating...a while I was on the freeway and it wouldn't go past 3k RPMs.
Around this same time my fuel gauge seemed to get stuck as well and not move correctly.
I replaced rotor because it didn't seem to healthy and the car ran fine for a few hours but then problem started up again..
I threw codes and it gave me 2 pause 2 and 2 pause 4. first code is for coolant sensor, seemed fine. second code was for air intake sensor. that seemed fine at rest, but I need to get it heated up and then check the resistance...
what could the problem be? I am thinking it may be fuel related (filter or pump), though i really don't want to think it is because that'd be a pain.
Funny you meantion the ECU collant Temp Sensor, as my friend and I last night was able to diagnose that as his issue on his 1997 V6 Camry, with similiar symptoms. That sensor tells the ECU when the engine is warm, so now that it is not reading correctly, the car is always in "cold" mode.
Im going to guess you also smell some unburnt fuel after driving? And the collant temp sensor will ultimatley cause other CEL's to occur, as the car is not running correctly.
Did the codes come on at the same time as well? Or 2 seperate times?

Have you replaced the distributor cap lately? It is important to have bright, clean metal electrodes on the interior of the cap. This is the high voltage current path that goes from the rotor tip to the cap electrode, and then through the plug wire to the spark plug. .... After so many miles or hours of operation, the cap electrode will develop an insulating oxide film, that inhibits the current. Cleaning the electrodes is a temporary fix, but you should buy a new cap if you haven't done so.

You nailed it, unburnt fuel.......though I threw codes without having the CEL occur.
how costly of a fix was the coolant temp sensor? if it's cheap and easy enough I'mwilling to go into it blindly and replace it.

cap was replaced 15k miles ago...I cleaned up the contacts when I got the new rotor.
There is a graph on p. 35 of this module which shows the approximate resistance of the Engine Coolant Temp Sensor, as a function of temperature. ... You could check the expected value and maybe verify that the sensor is defective, or not.
...Probably give it a while to equalize temperature with ambient before taking value.
Guessing that the Gen 3 Temp Sensor is the same as the Gen 4.
Note that Air Intake Temp Sensor is the same as Engine Coolant Temp Sensor.

elaborate on what you mean by "air intake temp sensor is the same as engine coolant temp sensor" as in they are the same thing, or that the actual sensor used is the same in each case.
I'm quite sure ASG314 has nailed it. we unplugged the connector to the coolant temp sensor and drove around the block. once we plugged it back in the car died, bingo.
thanks again guys, specially ASG16...I think you pretty much hit the nail on the head and I replaced the coolant temp sensor and things seem to be okay (for now).
Good to hear! That gives me hope for my friends car now! It has a TRD S/C so it;s under a lot more stress. He's going to replace the sensor on Monday I think.

For the purpose of testing .... the resistance values of both parts will be the same. It's something called a thermistor, common to both parts.
.... Sounds like you have narrowed it down to the ECT Sensor. Probably be worth getting a new one and trying it out.
