| Item | Description |
|---|---|
| 1 | VCT units |
| 2 | Intake camshaft VCT solenoid |
| 3 | Camshaft position sensors |
| 4 | Exhaust camshaft VCT solenoid |
The VCT system varies the timing of the intake and exhaust camshafts to deliver optimum engine power, efficiency and emissions. The timing of the intake camshafts has a range of 62 degrees of crankshaft angle. The timing of the exhaust camshafts has a range of 50 degrees of crankshaft angle.
In the base timing position:
- The intake camshafts are fully retarded.
- The exhaust camshafts are fully advanced.
