b. Measure resistance from
engine
position
sensor
connector pin B to engine
block ground. Resistance
should be greater than 100k
ohms.
5. Inspect
engine
position
sensor for damage, including
metal debris on end of sensor,
damage to end of sensor
caused by camshaft gear or
flywheel
ring
gear,
oil
leakage
or
insulation
problems such as swelling,
and
damaged
electrical
potting in sensing end of
sensor.
Replace
damaged
engine
position sensor (WP 0093 00).
6. Check resistance of engine
position sensor:
If resistance is not as specified,
replace engine position sensor
(WP 0093 00).
a. Measure resistance from
pin A to pin D of engine
position sensor. Resistance
should be 1000-2000 ohms.
b. Measure resistance from
pin B to pin C of engine
position sensor. Resistance
should be 1000-2000 ohms.
7. Check for a short circuit
between coils by measuring
resistance from pin A to pin B
of engine position sensor.
Resistance should be greater
than 100k ohms.
If resistance is not as specified,
replace engine position sensor
(WP 0093 00).
8. Disconnect sensor harness
from engine ECU (794).
9. Inspect engine harness and
engine ECU connectors for
dirty, corroded, bent, broken,
and pushed back or extended
pins.
Clean and repair connector(s) as
required (WP 0111 00).
