Hi there. Thank you for using our service.

Codes P0016 and P0017 indicate a fault with cam timing, while P2004 indicates a fault with the intake manifold runner control; all three of which are equally very important and may require expensive repairs (depending on current engine condition and the shop doing the work, the cost can be anywhere from $4,000 to $9,000). Codes P03XX indicate cylinder misfires and are the result of the previously described faults.

Please keep in mind that codes are just an indication of certain circuits being out of parameter; a thorough visual inspection should be conducted before an accurate estimate could be given.

Please let me know if you have any other questions. Best Regards.
