I just bought this product, hooked it up correctly, but now my car throws check engine lights when it turned on. I can turn the Unit off and it will turn the CEL off. Has anybody ever encountered this before? O yea its on an 88 CRX Si. The code its throwin is a CODE 3, Manifold Absolute Pressure Sensor.

 

its not wired right , i will fix it for you for $20 , can do it tom if you want , i have installed a billion of these in ef's , its may fav vafc.

 

yea thats great and all but im not payin for no one to work on my car. u can be a nice person and tell me wuts up. cuz u gotta know what wires are mixed up. and if u dont its ok, im no dumb ass, i can figure it out. dont come on my thread and offer work for money cuz, i woulda went to a shop if i wanted to spend cash

 

lol , please dont get me started by being a smartass , you asked for help and i offered it , and if you could figure it out , you would have. Anyways , what wiring diagram did you use , On the harness for the vafc there are 2 wires for the map sensor , one goes to the ecu , one goes to the sensor. You have them backwards , switch the 2 wires around and you should have no check engine. How is the motor running with the cel , do you smell fuel ? Does it smell rich ?

 

damn man, sorry bout that lil frustrated bout the car. I be Wilin sometimes. But anyways, yea it smells like fuel. When the car first started though it cut right off. But then i hit it again and the CEL came on and it started.

 

switch those 2 wires around and it should fix your problem.

 

you're too nice.
