Hi to all, been all over looking for info on the above. No comms with KTS or ACR4. Will run cold, but as warms over-fuels and cuts out. O2 sensor reads rich. Back probing MAP does not read at all (0.13V on term 2 &3 Ground on term 1)No change with load. If 5v supplied to Term 3 on MAP, management behaves well. MAP output on term 2 changes with load. TPS also has normal function, good O2 function 0.1V - 0.8V Seems like supply to sensors lost. Tracing back to ECU and providing 5V at ECU pin gives same result. Trying to decide if ECU fault or supply fault, or wrong assumption. Pin data or wiring info would be great, Thanks to all, Tom
