DTC P1110 - Valve Timing Control (VTC)
- Check Power Supply
Turn ignition switch to OFF position. Disconnect VTC solenoid valve harness connector. See Fig 1. Turn ignition switch to ON position. Using a voltmeter, measure voltage between VTC solenoid valve harness connector terminal No. 2 (Brown wire) and ground. If battery voltage does not exist, check for blown fuse No. 21 or fault in Brown wire. Repair or replace as required. If battery voltage exists, go to next step.
- Check Output Signal Circuit
Turn ignition switch to OFF position. Disconnect ECM harness connector. Using an ohmmeter, check continuity between ECM harness connector terminal No. 114 and VTC solenoid valve harness connector terminal No. 1 (Yellow/Red wire). If no continuity exists, repair open in Yellow/Red wire. If continuity exists, go to next step.
- Check engine oil pressure and intake air system. Inspect VTC solenoid valve. See the SYSTEM/COMPONENT TESTS
article. Replace VTC solenoid valve as required. Disconnect and reconnect harness connectors in circuit and perform FINAL CHECK .
