i have a dumb question. The car i bought has an obd1 b18c in it (head is stamped 93 and came with obd1 parts but the obd2 ones were used, including original trans) and i have a 96. which is obd2. I heard that the CEL wont come on because of this and i want to know what it takes to get that to work again.

I know that i would have to use the paper clip trick but i at least want something!

tldr: obd1 in obd2 car, how do i get CEL to work?

 

which obd2 parts were used?

 

everything that wasnt the motor itself. IM, trans, etc... to my knowledge anyways.

 

well run the obd2 ecu and it should be fine.

 

I am, so does that mean the CEL and everything will work if something were to come up?

 

As far as i remember as long as the wiring, ecu, IM, injectors are OBD2 then the cel should come on if there was an issue. maybe try disconnecting a sensor like o2 and see if the CEl comes on. if not then you got a prob.

 

Crank sensor needed for obd2, obd1 doesnt come with that sensor. Im assuming alt. is switched over to obd2 since they r different too

 

yea forgot about the crank sensor
