1993 Toyota P/U problem.........

[Marc1973]

I have a 1993 Toyota P/U with the 22RE engine, and currently have 123,000 miles on it, it's automatic & 4x4.

I had an oil change about 5 days ago and all of a sudden my check engine light came on half way home and has stayed on for the last day and half.

I checked the oil level, radiator fluid, tranny fluid, and all is fine.

Truck seems a little louder and maybe a bit more sluggish, but I don't know if that's just in my head because of the light being on, and no radio on, listening to every little noise?

Today I took off the positive connection to the battery for a couple of minutes to reset the computer, and now the light is off and I took it for a short ride and it did not come back on.

Is it possible it was just a dummy light that came on or do you have any opinions of what the problem could be that caused this?

Thanks for any opinions,
Marc

Next time your check engine light comes on, have the codes read. Autozone will read codes for free. The check engine light can come on for a variety of reasons.

About half of the ECU codes stored on the first & second generation EFI Toyotas don't show a constant blinking check engine light therefore you must pull the ECU codes to see if a fault is registered.

To pull the ECU codes:

All 1980-1995 and including 1995 EFI equipped vehicle allow you to find engine and related faults by pulling the ECU (computer) codes without the need for a handheld OBDII diagnosis scanner,the sites listed below have the fault codes needed to pull the codes and the instructions on how to do it:

Pulling the ECU codes is the first thing I do to diagnosis a problem thereafter I reset the ECU to see if the same problems show up and if so I then take voltage measurements both with the engine running and not and compare with the factory service manual,I also close the ignition switch after a cold engine and also after a warm engine and compare them with the factory service manual.This technique will completely isolate your problem without having to do trial and error and it is the technique I use when repairing tv's,vcr's,home/car audio.
