Braking Sensor/Switch: Service and Repair

Pedal position sensor, replacing

Note! The illustrations in this service information are used for different model years and/or models. Some variation may occur. However, the essential information in the illustrations is always correct.

Preparatory work




Ignition off.
Press the brake pedal a few times until the pedal becomes stiff and rises slightly. This releases the vacuum in the power brake booster and thus prevents the O-ring from being sucked in when the pedal position sensor is removed.

Removal

Removing pedal position sensor




Disconnect the connector from the sensor.
Slacken off the snap ring around the mounting for the sensor slightly. Insert a narrow screwdriver or wedge. Press one end of the snap ring in approximately 10 mm. Press radially backwards in the groove for the snap ring.
Remove the sensor and the O-ring.

Installation

Installing pedal position sensor





Note! Check that the snap ring is in position in the groove. Check that the ends of the snap ring lie against the stop lug.

- The O-ring on the sensor
- lubricate the O-ring lightly using a soap solution
- the sensor for the power brake booster so that the locking lug goes into position.
Gently pull the sensor. Check that the sensor is secure.
Check that the snap ring is in position.
