2
The pulse generator
reports the crankshaft position to the ECU. The ECU uses this signal to calculate the ignition point for
5
each cylinder. Battery voltage is supplied to both ignition coils
ECU.
The coil on the fuel pump relay
switches on for a few seconds and switches off again. If you start with the engine running, the fuel pump relay will stay on.
The fuel pump
obtains battery voltage from the battery through the fuse and the contact on the fuel pump relay (continuous
8
positive polarity).
The throttle potentiometer (TPS)
connector AM or AR). The TPS is supplied with 5 volts of supply voltage (blue cable on connector AM or AR) by the ECU. The
black cable (on connector AM or AR) supplies the ground.
NOTE: See Chapter 8 for the adjustment of the TPS.
