Code P1345 Saturn Description

The P1345 Saturn diagnostic trouble code (DTC) specifically refers 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 modern engines, the camshaft and crankshaft must be synchronized for proper engine operation. The camshaft position sensor detects the position of the camshaft, while the crankshaft position sensor detects the position of the crankshaft. When these two positions do not correlate as expected, it can lead to poor engine performance, misfires, and potentially engine damage.

Tech Notes for P1345 Saturn

If this DTC started after recent internal engine repairs, inspect for proper engine mechanical timing. With the camshaft cover removed and the #1 cylinder at top dead center, make sure that the darkened chain links are lined up with the alignment marks on the exhaust and intake cam sprockets.



If a P0016 or P1345 is resetting without any engine performance concerns but the above information did not isolate a cause for the DTC, replace the Cam Phaser Actuator sprocket.

When is the Code Detected?
