Engine stalling
Loss of power
Poor fuel economy

Diagnosis

Diagnosing a P0016 code can be a bit tricky, as there are a number of possible causes. However, the following steps can help narrow down the problem:

1. Check the wiring between the CMPS and the computer:
Make sure that all of the connections are tight and that there is no damage to the wiring.

2. Test the CMPS:
You can do this using a multimeter or a scan tool. If the CMPS is not functioning properly, it will need to be replaced.3. Test the computer:
If the CMPS is functioning properly, the problem may be with the computer itself. This can be diagnosed using a scan tool.
