92 LS400 Trac Off and Engine Lights
Hi Forums I have a 92 LS400 with 138k miles. It runs and drives 100%. But about 1k miles ago the trac off and engine light showed up on my way home. So I checked the engine light and it is code 25 (air-fuel ratio lean malfunction). So i cleared the lights by disconnecting the fuse under the hood. They both came back on the next day. So then i tried changing the MAF, cleared the lights. After an hour of driving same thing lights came back on. I heard something about oxygen sensors but i want to be sure, any ideas?

As you can see, I have the same problem.
This is the post on my car, if you are interested.

Just bringing this post back to life to see if anyone has any input at all. TRAC system errors are tough to figure out. Will be doing a diagnostic on mine later today though so I will share my findings here.

have you guys followed the step by step troubleshooting procedures in the factory service manual under that CEL code?

if you don't have the factory service manual, you can get a membership to Toyota Technical Information System for $15 and have 2-3 days to look at the appropriate section
