Q: service engine soon

asked by on July 14, 2017

service engine light is on , so when i got checked with scanner it showed P0014 code. So what may be the issue.?

My car has 203000 miles.
My car has an automatic transmission.

There is a TECHNICAL SERVICE BULLETIN for the problem and need to reprogram the PCM to a new level. The code is for a cam sensor signal being misread by computer and this TSB needs to be done before replacing any parts. Reference Number(s): 01-06-04-052B
