Be sure to take the measurement at
right angles to the phonic wheel and
at the point of a tooth, not a depres­
sion.
Checking gap
Because the rpm and TDC sensor is secured
directly to the engine block, gap and angular
position do not require adjustment. If a fault
is suspected, the gap can be checked as fol­
lows:
- remove the rpm and TDC sensor;
- check that the distance between the sensor
contact surface and phonic wheel tooth
corresponds to the sum of sensor probe
length (34.5 mm) and gap (0.8 - 1.5 mm).
KNOCK SENSOR (0.261.231.007)
The knock sensor is located on the rear of
then engine block, between cylinders 2 and
3.
Refer to the fuel system section for the 1998
20V engine for a more detailed description of
operation.
Recovery
Ignition advance delay: 8° - 9° according to
engine speed.
Knock control deactivation
If the fault relates to the sensor interface cir­
cuit, the ECU assumes an ignition advance
delay of 10°.
Wiring connector
The numbers in boxes indicate the corre­
sponding control unit pins.
