by the info you gave, the ecu code is the same as the head code (my h22a1 head/ecu code is p13)
makes sense since the ecu harness primarily connects to the head as far as sensors go.
Pistons are stamped with the same codes.
Actually kind of irritating because for many cars the OBD1 and OBD2 ECUs have the same code. Only way to tell the difference is the connector. Can make dealing with junkyards irritating.
