Code P1345 Isuzu Description

When the diagnostic trouble code P1345 is triggered in an Isuzu vehicle, it indicates a problem with the correlation between the crankshaft position sensor and the camshaft position sensor. These sensors play a crucial role in ensuring that the engine's timing is precisely synchronized for optimal performance. The engine control module (ECM) relies on data from these sensors to determine the correct timing for ignition and fuel injection. When the correlation between the crankshaft and camshaft positions is off, it can lead to a variety of performance issues and potentially cause long-term damage to the engine.

Tech Notes for P1345 Isuzu

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?

The ECM detected that the cam and crank sensor positions were out of time
