NOTE
Check to make sure that the following conditions are satisfied when using this “DTC Confirmation
Procedure”.
• The following DTCs are not detected: DTCs related to CKP sensor
1) With ignition switch OFF, connect scan tool.
2) Turn ON ignition switch and clear DTC by using scan tool.

DTC Troubleshooting
Step
Action
Yes
No
1
Was “Engine and Emission Control System Check”
performed?
Go to Step 2.
Go to “Engine and
Emission Control
System Check”.
2
CMP sensor and connector for proper installation check
Is CMP sensor installed properly and connector connected
securely?
Go to Step 3.
Correct.
3
CMP sensor power supply voltage check
1) Disconnect connector from CMP sensor with ignition
switch turned OFF.
2) Check for proper terminal connection to CMP sensor
and ECM connectors.
3) If connections are OK, turn ignition switch to ON
position.
4) Check that CMP sensor power supply voltage is battery
voltage between CMP sensor connector and vehicle
body ground.
Is it in good condition?
Go to Step 4.
CMP sensor power
supply circuit is open or
shorted to ground.
4
Wire harness check
1) Turn ignition switch OFF position.
2) Disconnect connector from ECM.
3) Check that CMP sensor circuit is as follows.
• Wiring harness resistance of CMP sensor signal
circuit is less than 3
Ω
.
• Insulation resistance of each CMP sensor signal and
ground circuit between CMP sensor connector and
vehicle body ground is infinity.
• Insulation resistance of wire harness is infinity
between CMP sensor signal terminal and each other
terminal at CMP sensor connector.
• Circuit voltage of each CMP sensor signal circuit and
ground circuit is 0 – 1 V with ignition switch turned
ON.
Are they in good condition?
Go to Step 5.
Repair or replace
defective wire harness.
5
CMP sensor signal circuit voltage check
1) Check that CMP sensor signal circuit voltage is 5 V
between CMP sensor connector and vehicle body
ground.
Is it in good condition?
Go to Step 6.
Substitute a known-
good ECM and recheck.
