Action in service

Rectify any faults saved on monitoring the voltage supply for the sensor system/actuators (5 V) (voltage outside the valid range) first.

Check intake system and crankcase for leaks.

Check throttle valve (contamination, carbon residue, icing).

Check wires and plug connections between the following components:

• DME
• Intake pipe pressure sensor

Check wires and plug connections between the following components:

• DME
• Electromotive throttle actuator

Replace intake pipe pressure sensor.

Renew electromotive throttle actuator.

Renew pressure sensor before throttle valve.
