Code P1145 Description
The P1145 diagnostic trouble code (DTC) refers to the Intake Valve Timing Control Performance Bank 2. This code indicates a problem with the intake valve timing control system on the bank 2 side of the engine. The intake valve timing control system is responsible for adjusting the timing of the intake valves to optimize engine performance and fuel efficiency. When this system is not functioning properly, it can lead to reduced engine performance, decreased fuel efficiency, and potential engine damage if left unresolved.
Common Causes of P1145
- Faulty intake valve timing control solenoid
- Wiring issues or electrical problems
- Mechanical issues with the intake valve timing control system
- Engine oil sludge or debris blocking the intake valve timing control components
- Engine timing chain or belt issues
Symptoms of P1145
- Reduced engine performance
- Rough idling or stalling
- Decreased fuel efficiency
- Illuminated check engine light
- Engine misfires
How to Fix P1145
- Diagnose the specific cause of the P1145 code using a scan tool and inspecting the intake valve timing control system components.
- Replace the faulty intake valve timing control solenoid if necessary.
- Repair any wiring or electrical issues that may be affecting the intake valve timing control system.
- Clean or replace any components affected by engine oil sludge or debris.
- Check and adjust the engine timing chain or belt if needed.
Cost to Fix P1145
