Modern vehicles are equipped with camshaft and crankshaft position sensors that send data to the powertrain control module (PCM). The PCM uses the information to control engine timing. If the camshaft sensor develops issues, it could trigger the P1345 code.
What Does the P1345 Code Mean?
Diagnostic trouble code (DTC) P1345 stands for “Camshaft Position Correlation.”

Note: The definition of code P1345 may be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.
P1345 On a Chevy
Let’s look at what triggers this trouble code in Chevrolet vehicles. In a Chevy, the camshaft and crankshaft position sensors send data to the PCM. If the sensors malfunction, they can send wrong data to the PCM and affect engine timing.
If you drive a Chevy, your scan tool will retrieve a P1345 code if your crankshaft or camshaft position sensor is malfunctioning. Note, however, that on some older Chevrolet models, the code points to a problem with the distributor.
What Are the Common Causes of the P1345 Code?
- Bad camshaft or crankshaft position sensor
- Malfunctioning distributor (or incorrect positioning)
- Issues with harness and connections
- Stretched or jumped timing chain
- Issues with the variable valve timing system
What Are the Common Symptoms of the P1345 Code?
- Poor engine performance
- Hard start
- Engine misfires
- Ticking noise
How to Diagnose the P1345 Code
The code P1345 doesn’t have a universal diagnostic procedure because vehicle structures vary depending on their make.
If you’re not sure how to diagnose the issue, it’s always a good idea to take your ride to an auto repair shop. Licensed mechanics know how to diagnose the issue correctly.
You can also try to diagnose the trouble code yourself if you have the right tools and automotive know-how. Search for P1345 diagnosis tutorial videos online that are specific to your vehicle for reference.
How to Fix the P1345 Code
Resolving a P1345 code can be tricky, especially if you don’t have in-depth knowledge of how the crankshaft and camshaft sensors operate. In that case, it’s better to let an ASE-certified mechanic resolve the issue to ensure your vehicle is in good hands.
But if you’re confident you can resolve the trouble code on your own, make sure to read up about this trouble code before starting. Resources like Chilton can give you vehicle-specific information that can help you fix code P1345.
