Crankshaft Position (CKP) Sensor Inspection

Visual check
• Check that O-ring is free from damage.
• Check that end face of sensor and signal pulley tooth
are free from any metal particles and damage.
Performance check
1) Remove metal particles on end face of CKP sensor,
if any.
2) Arrange 12 V battery (1) and connect its positive
terminal to "Vin" terminal (2) and negative terminal to
"Ground" terminal (3) of sensor. Then using
ohmmeter, measure resistance between "Vout"
terminal (4) of sensor and negative terminal of
battery by passing magnetic substance (iron) (5)
while keeping approximately 1 mm (0.03 in.) gap
with respect to end face of CKP sensor.
If resistance does not vary as specified below,
replace CKP sensor.
CKP sensor resistance
Resistance varies from less than 220 Ω (ON) to
infinity (OFF) or from infinity (OFF) to less than 220
Ω (ON)
