Trouble codes do not represent a diagnostic and consequently parts should not be replaced merely because they are listed in a code description. Trouble codes are best considered indicators or clues as to the general area of the problem. If the camshaft position sensors were not actually directly tested, and their output viewed on an automotive scope, but nevertheless replaced, they might have been perfectly good. To obtain an actual diagnostic and a pinpoint identification of the fault, the recommended service is a check engine light diagnostic. If you request that service the responding certified mechanic will actually test components and determine the root cause. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
