Checking Power and Ground Terminal - Throttle Unit

Checking the power supply and ground terminals for the throttle unit

Checking the power supply and ground terminals for the throttle unit

Checking the power supply
- Check the fuse for power supply to the electronic throttle unit. If the fuse is blown, check the circuit after the fuse. Check for a short-circuit to ground
- Check power supply to throttle unit #6. Voltage should be approximately battery voltage.

Checking the ground terminal
- Check the ground lead between throttle unit terminal #5 and engine ground terminal ETM 31/91. Check for an open-circuit
- Check the ground terminal for the throttle unit. Check for contact resistance and oxidation.
Remedy as necessary
