What does the code p1345 mean on a Chevy?

P1345 CHEVROLET Meaning The Crankshaft Position (CKP) sensor is a permanent magnet generator, known as a variable reluctance sensor. The magnetic field of the sensor is altered by a crankshaft mounted reluctor wheel that has seven machined slots, 6 of which are equally spaced 60 degrees apart.

What is the CKP sensor on a p1345 Chevy?

P1345 Chevrolet Description. The Crankshaft Position (CKP) sensor is a permanent magnet generator, known as a variable reluctance sensor. The magnetic field of the sensor is altered by a crankshaft mounted reluctor wheel that has seven machined slots, 6 of which are equally spaced 60 degrees apart.

How does the camshaft position sensor work on a Chevy?

The Camshaft Position (CMP) sensor is triggered by a notched reluctor wheel built into the exhaust camshaft sprocket. The CMP sensor provides 6 signal pulses every camshaft revolution.

Can a failed CPS cause a p1345 engine code?

While a failed CPS or CMP can cause a P1345 code, it is usually easier diagnosed as you will likely also receive an engine code for whichever sensor has failed. Additionally, you can easily inspect both of these sensors to insure they aren’t gunked with oil or have bad connections.

What causes an engine code on a Chevy Vortec?

While this error code can be caused by a faulty camshaft position sensor (CMP) or crankshaft position sensor (CPS), the issue a lot of the time relates to engine timing. On older Chevy engines, specifically the 5.7 Vortec, for which this code is most common, the problem generally stems from the Distributor positioning.

When to use fault code p1345 in OBD II?

OBD II fault code P1345 is a code used by General Motors – that is defined as “Crankshaft Position (CKP)-Camshaft Position (CMP) Correlation”, and is set when the PCM (Powertrain Control Module) on GM models detects a mismatch (correlation fault) in the input data from the Crankshaft -,…
