Crankshaft Impulse Sensor, Diesel Opel Combo C

Note. This operation does not apply to F9Q, G9T engines and Vectra-B.

Objective:

Checking Operation of the impulse sensor on the crankshaft.

Measurement:

Plot of voltage at the signal output for the impulse sensor on the crankshaft.

Preparation:

Switch off the engine and ignition.

Connections:

Procedure Tech 31:

1. 1. Download the Reference curve.
2. 2. Start the engine and allow it to idle.

Reference Curve:

The signal plot should be continuous and regular. If the amplitude of the signal plot varies greatly, in spite of the engine speed remaining constant, the sensor disc and sensor must be checked for soiling, concentricity and correct shape.

Procedure Tech 32:

1. 1. Download Setup file (the Tech 32 uses only Setup files, no reference curves).
2. 2. Start the engine and allow it to idle.
