2002 Chevrolet Savanna 5.0L Engine P1345 Fault Code: Camshaft Position/Crankshaft Correlation Issue

Model: 2002 Chevrolet Savanna Fault Code: P1345 Posted: 2009-06-02 21:08

I'm assisting my father with repairing his 2002 Chevrolet Savanna Van 2500 (5.0L V8 engine). After the check engine light (MIL) came on, we used an OBD-II scanner and retrieved a P1345 trouble code — indicating a Camshaft Position / Crankshaft Position Correlation problem. We have already replaced several components including the distributor, mass air flow sensor, engine temperature sensor, camshaft position sensor, and the timing chain/gear. The vehicle starts normally with proper spark, confirming that the distributor is installed correctly. However, the P134-5 code persists and the MIL remains illuminated. We are seeking reliable guidance on how to resolve this issue. Specifically, does a scan tool support 'resynchronization' of the camshaft and crankshaft positions? Are there known procedures or tools (e.g., specific scan tools) that can perform this function? Additionally, if any step-by-step guides exist for replacing these parts in a 2002 Chevrolet Savanna, we would greatly appreciate links to such resources.

A scan tool with resync capability is required to re-establish the camshaft and crankshaft position correlation. This function is not available on basic code readers.

My 2004 model Spot On scanner detected P1345, but I couldn't find a resync option in its menu — this suggests that the tool may lack advanced functions like cam/crank synchronization.

The 'Spot On' scanner mentioned is likely a specific brand or model. Standard OBD-II code readers do not support resynchronization of camshaft and crankshaft positions — this function requires specialized diagnostic tools.

I successfully resolved the P1345 issue on three 2002 Chevrolet Savanna vans by manually adjusting the distributor side-to-side while slowly turning it, then observing when the check engine light turns off. I don't fully understand why this works, but it consistently resolves the code. This method may be a viable alternative if resync tools are unavailable.
