I have a 97 EX Coupe, its built and boosted with a chipped P28 Tuned on Chrome with a conversion harness. What wire do I have to jump to read the codes. The only 2 pin plug I found was this big rectangular clear one with blue wires. Jumping it does nothing, if its plugged in the CEL flashes 1 time if i leave it there (turn on the ignition without starting the car), it flashes 1 time after the fuel pump finishes priming. If I unplug it, it doesnt flash at all. If I jump it, it flashes 1 time. 1 Flash would be O2 sensor, except I know its good. I rewired it and tested it in another car. Not only that but if I unplug other sensors it doesnt change the CEL at all. It still only flashes that 1 time. I really need to figure out wtf this code is. Its making the car run slow.

 

cmon people i need this fixed. My 300HP car is running like a 200HP car.

 

have you tried bringing it to auto zone? they have the code reader they can just plug in and it'll tell you what it is. it's free as well, so it doesn't hurt to try.

 

 

Why dont you try disabling it on the ECU chip and trying it again? Maybe you need to run it in closed loop

 

I didnt know you could plug in a OBD1 car? Because I know that the regular service connector doesnt work on OBD1 cars. And I cant disable anything on the chip as I dont have the hardware to do that, the tuner is the one who programmed it.

 

Ok I figured out how to check it and I found a Code 6 which I fixed. My question now is, does the engine coolant temp sensor make it run in a safe mode? Because my car feels slower than its supposed to. Also I havea Code 72 on the SRS Light and I need a list of SRS Codes so I can figure out what it is.
Now something strange happens when I turn on the ignition. The CEL Flashes 3 times really fast and then turns off. The Connector isnt jumped anymore and if I jump it I get no code. Is it flashing a Code 3 for MAP Sensor because I have a 3Bar and the eCtune like doesnt start instantly or something? Because it turns off right after the 3 fast blinks.
