we just completed my engine swap. the problem is the check engine light will not go off, and the tackometer doesn't work. is there any way to fix this. the check engine light is my main concern, it is a brand new gsr motor and i am almost positive nothing is wrong with it. does any one know whats going on.

check engine light doesn't mean something is wrong with it, as the broken or malfunctioning... something might not be connected right or emmissions might be setting it off... best bet would be to pull the check engine code from the ecu and find out exactly what the problem is

 

[b18c1sol]

how exactly do you pull a code from an ecu. this may be a dumb question, but please no dumb answers.

 

[Sean]

Pull codes by jumping out the plug with (2) connectors above the ECU (passenger side, under glove box)... it will be in a green case with engine in the ON position, but not running. Sean

check that you connected the knock sensor if you arent running a chipped ECU. that is a big cause for check engine lights for DOHC swaps.

the motor has a sensor on the plenum on the intake, well i have an aem intake and there was no where to plug that sensor into. so there is a plug with no mate, could that be the problem.

 

[Roro]

Since its OBD2 yeah thats a problem, you might want to convert over to OBD1 if you havent already. Grab that code from the ECU and see what it says...

 

[Del La Sol]

sounds like your intake is obdI and your engine is obdII... like Roro said you can convert to OBDI which is probably necessary, you could try and drill an extra hole in your intake and plug that extra sensor in too maybe

thanks but we figured it out, we had to tap the intake with the mate to the empty sensor. it was no problem.
