Ok... Need help ASAP. We recently put a D16Z6 into a '91 hatch. The swap itself went smoothly until startup. At startup we are knowing getting a MIL/CEL Code #9 (#1 cylinder position defective circuit or unplugged/defective sensor). Knowing that the sensor is in the distributor, we started there. We tested it and found that it was bad. So we went and bought a new (remanufactured) distributor. We put the new one on and we are still getting the code. We have check and double-checked the timing and it is dead on. We are running out of ideas on what to check or change. Any ideas?

 

Are you running thr right ECU/ECM?

 

I'm having the exact same problem in my 92 GS-R. I've replaced the whole distributor housing about 3-4 times.

We're going to replace it one last time today, reset the ECU properly, and I think I'm going to buy a new cap also. I really have no clue on how to fix it, I've tried replacing it a million times. We've timed it, did a full tune-up, replaced rotor,cap, plugs, wires. Nobody I've talked to knows what to do, even though a few people have had the same problem.

Some guy I talked to said it was the crank angle sensor in the distributor. It made his car idle REALLY low and his car cutoff at 3-4k RPMs, instead of going to the redline. I've had that same problem with one of my distributors. With the one I have on now, the check engine light is on, it idles low, but I can take it all the way up through 8000 RPMS. He says its the crank angle sensor that makes your car idle low, and he replaced his by taking two distributor housings, and taking the parts out of both to make one good one.

 

We re-ran the wires from the ECU to the distributor and the code it now go. The pins were right but there must have been a break in the wire or a wire crossed somewhere.

 

Hey, the other distributor he used to swap out the parts, was it the same obd version gsr dist. also? I'm having the same problem. My car wont go pass 3500 checked my ecu and it threw the code #4 which is the crankshaft position sensor.
