Hey guys, been stalking this forum for a bit now, And I have a few questions for you.
As of the moment the car is a 1993 Del sol si, It is swapped with a b18c5 and an si transmission. The car has a p73 ecu with a skunk2 chip in it. The car has 160 psi across all 4 cylinders. It has an intake, exhaust and dc4-1 headers. Also has a stage 3 clutch.

The problem at the moment is, is the CEL light is on, it is giving codes 7 and 9. code 7 and 9 are the TPS sensor and the crank sensor, is there any way to hard wire or better yet fix the light? I looked at the TPS sensor and its plugged in, so im not sure why it would be giving the CEL light?

If you have any other questions I can try my best to answer you. Also I am unsure of if the car is obd2 or obd1. A p73 is obd2 so im guessing the car is obd2. Is there any way to check the distributer to see what that is? Also the harness looks like it was half *** rigged up because they used crush connecters for the plug on the distributer.

Thank you very much guys.

Bump, and also, does honda still sell replacement parts for the little compartment by the cig lighter? The door is broken and theres no inside to it.

Your description of the engine wiring and harnesses probably already answers your question about the cause of your problems. Test and solder the CYP sensor (code 9) and TPS (code 7) wires and replace damaged connectors. Then go from there.

does it drive weird when u step on it. i have the same two cel coming out and the previous owner i guess have had no type of experience working with wires.lol

Thanks for the change of title, and I was told that the crank sensor wasnt hooked up, I knew that problem, but where is that sensor located? And The TPS sensor was really what I was asking, I cant figure out what is wrong with that,


I drove the car for about an hour on the highway, and truthfully, i think it ran fine. Definatly smoked. But I figure that its the head because the compression is fine?

The CKP, TDC, and CYP sensors are all located inside the distributor. Use a multimeter to test the resistance of the CYP sensor. It should be 350-700 Ohms. If resistance is fine, use the multimeter to check for a short or open in the two CYP wires that run from the distributor to the ECU.

Test whether the TPS gets 5 reference volts from the ECU. If so, measure the TPS output voltage at closed and wide open throttle. The voltages should be ~0.5V and ~4.5V, respectively. Then test the three TPS wires for a short or open.

I dont have a volt meter available at this time, but when I get ahold of one, ill definatly do this, thank you very much

crank sensor is below next to the alternator on obd 2 engines it comes out right by the crank pulley, running a chipped p28/p06 ecu would get rid of the crank sensor issue since obd1 motors had it wired into the dizzy.
