GM P1345 Error Code: How to Fix It

Q: What causes GM P1345 error code?

GM P1345 is typically caused by a stretched or loose timing chain, faulty crankshaft or camshaft position sensors, damaged timing chain components, or incorrect engine timing after recent repairs.

Q: Can I drive with P1345 code?

It's not recommended to drive with P1345 code as it indicates timing issues that can cause engine damage. The vehicle may stall, have poor performance, or fail to start. Have it diagnosed and repaired as soon as possible.

Q: How much does it cost to fix P1345?

Repair costs vary widely depending on the cause. Sensor replacement typically costs $100-300, while timing chain replacement can cost $800-2000 due to labor intensity and part costs.

Q: Is P1345 a serious problem?

Yes, P1345 is a serious issue that affects engine timing. Ignoring this code can lead to engine damage, poor fuel economy, emissions problems, and potential engine failure if the timing chain breaks.

Q: How do I prevent P1345 from happening again?

Regular oil changes with proper grade oil, replacing the timing chain at manufacturer intervals, and addressing engine performance issues promptly can help prevent P1345. Avoid letting the engine overheat as this can damage timing components.

Abstract

The GM P1345 error code indicates a problem with the crankshaft to camshaft position correlation, meaning the engine's computer has detected that the crankshaft and camshaft are not properly synchronized. This timing issue can cause poor engine performance, rough idling, stalling, or prevent the engine from starting altogether.
