Hi guys.
My UZ powered Monaro has been going strong for about 5 or so years now. The only real problems have been an having to replace an ECM about 2 years ago. Now I think my second ECM might be dieing as well.
If I stab the go pedal the engine will rev to 3500 to 400rpm then cut off the injectors. The engine dies until the revs drop to about 2000rpm then injectors re energize to start the cycle again.
Checking for codes I get a 41 TPS fault. After about 30hrs of checking wiring and testing the only thing I have found wrong is the voltage between TPS terminals IDL1 and E2. I get 0.0v with throttle closed and only 1.5v open. At open it should be 9 - 14v.
Question is, is the ECM stuffed or can something be causing the lack off voltage?
