Question about 1992 Toyota Xtracab
I need to know the correct process for reading the ECU fault codes on my new 1992 V6. It just came on today.
Code 25 equates to a problem with the "heated" oxygen sensor. The code is "Air-Fuel Ratio Lean", from the heated O2 sensor...This is the one with more than one wire. I'd replace it. But, you would do much better if you get a genuine Toyota part. I have observed that the "aftermarket" sensors do not develop the proper VDC (.045; for 90 seconds). New ones from the aftermarket do not fix this at times. Hope this helps, and thnaks for choosing FixYa. The graciousness of a FixYa rating for my assistance would be greatly appreciated. Thanks.
