Crankshaft Position (CKP) Sensor InspectionS6RW0D1306015
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)

• Connect MAF and IAT sensor connector securely.
Intake Air Temperature (IAT) Sensor InspectionS6RW0D1306020
CAUTION!
Do not heat up MAF and IAT sensor more
than 100 °C (212 °F). Otherwise, MAF and IAT
sensor will be damaged.

• Check sensor O-ring (1) for damage and
deterioration. Replace as necessary.
• Blow hot air to temperature sensing part (2) of MAF
and IAT sensor (3) using hot air drier (4) and measure
resistance between sensor terminals while heating air
gradually.
If measured resistance does not show such
characteristic as shown, replace MAF and IAT sensor.
Intake air temperature sensor resistance
