Check engine light on

My Yota did the same thing and it was a sticky EGR valve. Replaced it and I havent had the problem since

I am having the same issue as Josh Bukoskey. Surely we aren't the only ones with that problem.

The issue/result.

I did end up taking the computer out and sending it in to get checked. It tested out fine and nothing wrong so the computer testing company (based out of FL) sent it back. When I put it back in everything was good for a few days and then the same issue happen again.
After a lot of headaches I figured out that the issue was indeed the computer. I ordered a completely new one and the one sent me was bad (after more headaches). Sent it back and got a new one and everything works great. I also replaced the MAF after already replacing before. There were other frustrations while looking for the problem.

If I learned anything from this its just because a part you get is new doesn't mean its good.

I want to thank you for your response. Finally found an ECU and it runs great now. Many Thanks again.

Service engine soon light is on: Are the codes for this engine the same as for a 1991 Corolla with 4AFE engine?

When I do the paperclip test: I get code 25

Anyone know what this means?

Thanks

Thanks: Does the 22RE have 1 02 sensor or 2? If 2 where is the second one?

When my check engine light comes on on my 93 Toyota pick up four-wheel-drive 22r it runs like crap sometimes or loses half of its power. I've had every diagnostic test done to it and it reads no code stored to computer. When the light comes on and stays on it lose half of his power when it blinks it jerks real hard.

Yes iv check them they are good an used but don't look to bad.

I havnt check the. Cadillac converter. It has 170000 miles

I have a 93 toyota pickup 4wd with v6 engine with manual tran. Last year I had work done on the trans. When I got it back the first time I drove it the check engine light came on. The second time I drove it, it stalled and I had to have it towed. They found wiring for oxygen sensor shorted out. Also found EFI Relay broken and R&I relay fuse. They did a Computer Diagnostics: Coce 21=Oxygen sensor signal. They repaired the wires and truck runs. I replaced the oxygen sensor, but the check engine light is still on. I had it checked and there doesn't seem to be power coming from the computer. Is it possible that the wires shorting out (they got burned from the exhaust pipe) could cause the EFI relay and R&I relay fuse to blow. Could it also damage the computer? :Roll:
