MY93 WRX Speed Sensor Circuit Fault
HELP!!!!!!
I have an my 93 impreza, after curing the engine check light fault, and fitting a new MAF sensor and new cam position sensor the ECU is still shutting down into limp home mode.
The engine check light is showing that there is a fault with the Speed sensor circuit, the speedo cable is fine and the dash is showing both RPM and revs which are both fine. The ECU has been reset however the car will drive fine for fifteen minutes then the ECU shuts down and returns to limp home mode.
Am I looking at an internal fault within the ECU or in the wiring harness.
Help would be appreciated.
