right angles to the phonic wheel and
at the point of a tooth, not a depres-

Checking gap
Because the rpm and T D C 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 T D C sensor;
- check that the distance between the sensor
contact surface and phonic wheel tooth
corresponds to the sum of sensor probe
length ( 3 4 . 5 mm) and gap ( 0 . 8 - 1 . 5 mm).
KNOCK S E N S O R (0.261.231.007)
The knock sensor is located on the rear of
then engine block, between cylinders 2 and

Refer to the fuel system section for the 1 9 9 8

cuit, the E C U assumes an ignition advance
