i am trying to get my truck back to smog legal and one of the things on the list is the engine light needs to come on for a second or so when you first turn the key on to start the truck but it does not.......i was wondering if anyone has had this problem with any luck in fixing the problem i tried a couple of search words with no luck as of yet i will keep trying but would really like some help if any is out there...thanx p iii

 

ps........the truck is in cali and runs fine just having that one problem, once again thank you for any help

 

Probably a burnt out bulb. Any auto parts store has replacements.

 

thanks for the quick reply but that was the first thing i tried and no luck........p iii

 

Is it EFI or carb? Does a carb truck even have a check engine light?

 

Yes, telling us a little about WHICH Toyota truck you have might help.

The engine light is more commonly called the CEL (or Check Engine Light). Its signal is available on the W connector in the diagnostic connector, so check it there and you'll bypass the wiring to the panel. Then, if necessary, trace it back to the ECM using the schematic. http://www.ncttora.com/fsm/1990-1995...emci/eng3r.pdf

Be prepared for some codes, though. Even though your truck runs "fine," there is probably a reason your predecessor tried to hide the CEL.

 

sorry guys it is a 1986 toyota 4wd it was a turbo truck but the motor was blown so the po put a 22re in it and yes it did have a check engine light but it stopped working.......ps i have checked the bulb thank you guys for the quick responses i will keep trying to figure it out
