Camshaft Position (CMP) Sensor Inspection

Visual check
• Check that O-ring is free from damage.
• Check that end face of sensor and signal rotor tooth
are free from any metal particles and damage.
Performance check
1) Remove metal particles on end face of CMP 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 CMP sensor.
If resistance does not vary as specified below,
replace CMP sensor.
CMP sensor resistance
Resistance varies from less than 220 Ω (ON) to
infinity (OFF) or from infinity (OFF) to less than 220
Ω (ON)
