Tach Needle sweep issue.

Recommended Posts

Hi Simon,

Thanks for the response.

ECU = G4 Plugin into a 1992 300zx ... engine = Twin Turbo

Fault has developed ... Have fitted new Cams and discovered issue upon trying to start the car for 1st time.

ECU is giving the following faults:

AN6 at 5V

AN V6 at GND

AN V3 at GND

AN T2 at V5

AN V 6 is the Oxy input

AN V 3 is the TPS

AN T2 is the fuel temp

All assuming it is using the stock configuration.

TPS might have an effect on the starting. But the error could just be due to the sensor being unplugged at some point.

I would start by clearing the errors to see if they come back up.

I would also check for any ground wires that might have been left off after the CAM change.
