Question

I have checked the shift position sensors and the A bank sensor is definitely the sensor with the problem. All voltages are good and the out put signail drops from 5 Vdc to 0 Vdc. But nothing happens. The other sensor turns on the fuel pump and other relays when it changes the voltage. There may be a break in the wiring but I have no wiring diagram and not sure we're the other end of the harness ends up.

Hi there

In this case I would start by replacing the cam sensor. If the voltage is dropping off then the sensor itself is the likely issue. As for the wiring, this ends up at the computer.
