The M62 I worked on has either or both of those errors. Swapped some CPS from another M62 in the shop and problem vaporized. There's two power side and the error is a generic one that doesn't say intake or exhaust.

My first repair on my M54 was replacing the CPS on the intake. If that was my engine it would have been my first thing to do replace all four.

Use only OEM quality CPS. They are very very sensitive and perfection counts in this department.
