'91 ecu troubles
#34
My CMP is 3-wire so that makes it a hall type. The CKP is 2-wire.
Yes I checked each wire including the shield. There is also 5 volts reference voltage on all sensors. My biggest concern is the shorted ignition coil which may have damaged the driver ic. Am still waiting for STI to feedback me on my queries.

Pin 38? I did not know that an OBD2 ecu has a flash pin. Now I can have fun. Thank you. I found the link below for the dtc. Is this ok?

But then I need flash codes not just trouble codes since I do not have the proper scanner.
