P1337 Fault Code

Acura – CRANKSHAFT SPEED FLUCTUATION SENSOR NO SIGNAL

For both Acura and Honda, fault code P1337 is logged when the powertrain control module (PCM) has detected an issue with the crankshaft speed (CKS) sensor.

The code indicates that there is no signal being sent from the CKS sensor to the PCM.

The CKS is an incredibly important component when it comes to the safe and proper functioning of the engine.

It is also known as the crankshaft position (CKP) sensor, as the PCM can determine the position and speed of the shaft with only one of these parameters.

The PCM needs to know the position of all of the shafts in the engine at all times, so that it can ensure all of these shafts are perfectly in time with one another.

This is to ensure proper performance and allow for optimizations by the computer. If the CKS sensor is not functioning correctly, the PCM cannot know the corresponding position.

Additionally, if the PCM cannot determine the position of the crankshaft, the vehicle will very likely be able to start at all or permanently stop running the next time it is switched off.

Any shaft position sensor issue can hide more serious problems, meaning it is important to have these issues resolved immediately.

Audi – CAMSHAFT POSITION SENSOR BANK 1

For both Audi and Volkswagen, fault code P1337 is logged when the powertrain control module (PCM) has detected an issue with the camshaft position (CMP) sensor in the first bank of the engine.

When logged in a Volkswagen vehicle, the description for this fault code gives more information on the problem, pinpointing that there is likely a short circuit in the CMP sensor circuit.

The CMP sensor is a vital component in ensuring the engine and its various shafts are functioning properly.

The PCM needs to know the position of all of the shafts in the engine at all times. This is to ensure proper performance and allow for optimizations by the computer. If the CMP sensor is not functioning correctly, the PCM cannot know the corresponding position.

This can quickly lead to a host of issues in terms of driveability.

Most vehicles will have a CMP for each camshaft. This fault code does not indicate where the intake or exhaust camshaft is at fault. This makes it important to assess both (or all) CMP sensor circuits when attempting to resolve this code.

Any shaft position sensor issue can hide more serious problems, meaning it is important to have these issues resolved immediately.
