CAUTION: The maximum amount by which the engine management system will adjust the camshaft timing (VCT control unit) is limited to 2 degrees. As a result of this an extremely high degree of accuracy is required for any work which affects the valve timing.

NOTE: Before performing diagnostic procedure, follow testing procedure. See TESTING PROCEDURE under SELF-DIAGNOSTIC SYSTEM. DTC Confirmation Test Malfunction is detected when an excessively high or low voltage is sent to ECM from Intake Valve Timing Control (IVTC) position sensor. Possible causes are: IVTC position sensor circuit open or shorted. Faulty IVTC position sensor. Faulty Crankshaft Position (CKP) sensor (REF). Faulty CKP sensor (POS). Faulty Camshaft Position (CMP) sensor. To set DTC, turn ignition on and select DATA MONITOR with scan tool. Slightly increase engine speed and hold for at least 10 seconds. If first trip DTC is detected, go to PROCEDURE . Reference Values For ECM Terminals and Reference Values, see Fig. 39 . Procedure 1. Turn ignition off. Loosen and retighten engine ground bolts. See Fig. 5 . Disconnect appropriate IVTC position sensor harness connector. See Fig. 40 or Fig. 41 . Turn ignition on. Measure voltage between ground and IVTC position sensor harness connector terminal No. 3 (Black/White wire). If battery voltage exists, go to next step. If battery voltage does not exist, repair open or short circuit and retest system. See WIRING DIAGRAMS article. 2. Turn ignition off. Check continuity between engine ground and IVTC position sensor harness connector terminal No. 1 (Black wire). Also check circuit for short to voltage. Repair circuit as necessary and retest system. If ground circuit is okay, go to next step. 3. Disconnect ECM harness connector. See Fig. 3 . Check continuity of Yellow/Green wire between right IVTC position sensor harness connector terminal No. 2 and ECM harness connector terminal No. 79, or
