P1145

Component Description
Intake valve advance unit position sensors are located in the front cylinder heads in both right/left banks.

This sensor uses a Hall IC (element).

The cam position is determined by the intake primary cam sprocket concave (in three places). The ECM provides feedback to the intake valve timing control for appropriate target valve open-close timing according to drive conditions based on detected cam position.

On Board Diagnosis Logic
Malfunction is detected when an excessively high or low voltage from the sensor is sent to ECM.

Possible Cause
- Harness or connectors
(Intake valve timing control position sensor circuit is open or shorted)
- Intake valve timing control position sensor.
- Crankshaft position sensor (REF)
- Crankshaft position sensor (POS)
- Camshaft position sensor (PHASE)

DTC Confirmation Procedure

NOTE: If "DTC Confirmation Procedure" has been previously conducted, always turn ignition switch "OFF" and wait at least 10 seconds before conducting the next test.

WITH CONSULT-II
1. Turn ignition switch "ON".




2. Select "DATA MONITOR" mode with CONSULT-II




3. Maintain the above conditions for at least 10 seconds.
4. If 1st trip DTC is detected, go to "Diagnostic Procedure".

WITH GST
Follow the procedure "With CONSULT-II" above.
