DTC Troubleshooting
Step
1 Was "Engine and Emission Control System Check"
performed?
2 CKP sensor and connector for proper installation check
Is CKP sensor installed properly and connector connected
securely?
3 Wire harness check
1) Turn ignition switch OFF position.
2) Disconnect connector from ECM.
3) Check that CKP sensor circuit is as follows.
• Wiring harness resistance of CKP sensor signal circuit
is less than 3 Ω.
• Insulation resistance of each CKP sensor signal and
ground circuit between CKP sensor connector and
vehicle body ground is infinity.
• Insulation resistance of wire harness is infinity
between CKP sensor signal terminal and each other
terminal at CKP sensor connector.
• Circuit voltage of each CKP sensor signal circuit and
ground circuit is 0 – 1 V with ignition switch turned
ON.
Are they in good condition?
4 Engine start signal check
1) Check starting motor circuit referring to Step 3 of "DTC
P0616 / P0617: Starter Relay Circuit Low / High".
Is check result satisfactory?
5 CKP sensor check
1) Check CKP sensor and sensor rotor referring to
"Crankshaft Position (CKP) Sensor Inspection in Section
