CAMSHAFT POSITION (CMP) SENSOR INSPECTION
A6E394018200W01
Caution
•
When foreign material such as an iron chip is on the CMP sensor, it can cause abnormal output
from the sensor because of flux turbulence and adversely affect the engine control. Be sure there
is no foreign material on the CMP sensor when replacing.
Note
•
Perform the following inspection only when directed.
Resistance Inspection
1. Disconnect the CMP sensor connector.
2. Measure the resistance between CMP sensor terminals A and B using an ohmmeter.
•
If not as specified, replace the CMP sensor.
•
If CMP sensor resistance is okay, perform the “Circuit Open/Short Inspection”.
Specification
400—550 ohms
Circuit Open/Short Inspection
1. Disconnect the PCM connector. (See F–43 PCM
REMOVAL/INSTALLATION .)
2. Inspect the following wiring harnesses for open or
short. (Continuity check)
Open circuit
•
If there is no continuity, the circuit is open. Repair
or replace the harness.
— CMP sensor terminal A (harness-side) and
PCM terminal 2M (harness-side)
— CMP sensor terminal B (harness-siede) and
PCM terminal 2J (harness-side)
Short circuit
•
If there is continuity, the circuit is shorted. Repair
or replace the harness.
— CMP sensor terminal A (harness-side) and power supply
— CMP sensor terminal A (harness-side) and body GND
— CMP sensor terminal B (harness-side) and power supply
— CMP sensor terminal B (harness-side) and body GND
