Code P1345 Pontiac Description
The P1345 diagnostic trouble code (DTC) for Pontiac vehicles relates to the Crankshaft Position-Camshaft Position Correlation. This code indicates that there is a discrepancy between the position of the crankshaft and the camshaft in the engine. In an internal combustion engine, the crankshaft is responsible for converting the up and down motion of the pistons into rotational motion, while the camshaft controls the opening and closing of the engine's valves.
Common Causes of P1345 Pontiac
- Faulty camshaft position sensor
- Worn timing chain or belt
- Malfunctioning crankshaft position sensor
- Issues with the engine's timing system
- Incorrect installation of timing components
Symptoms of P1345 Pontiac
- Rough idling or engine misfires
- Decreased fuel efficiency
- Engine stalling or hesitation
- Check Engine Light illuminated
- Lack of power or acceleration
How to Fix P1345 Pontiac
- Diagnose the issue using a scan tool to verify the P1345 code and identify the specific cause.
- Inspect the camshaft and crankshaft position sensors for any damage or malfunctions.
- Check the timing chain or belt for wear and proper alignment.
- Ensure the engine's timing system is functioning correctly and that all components are properly installed.
- Clear the DTC and road test the vehicle to confirm the repair was successful.
Cost to Fix P1345 Pontiac
The typical repair costs for addressing a P1345 code can vary depending on the specific cause of the issue. In general, repairing or replacing a faulty camshaft or crankshaft position sensor can cost between $100 to $300 each, including parts and labor. If the timing chain or belt needs to be replaced, the cost can range from $500 to $1000 or more, depending on the vehicle make and model.
