Thanks for your help

P0217 diagnostics are extensive and include diagnosing the IPDM, the coolant and sensors, as well as the fans and relays.
Are you doing the diag? Do you have a DVOM and the patience to fault trace these circuits?

What does that mean: DVOM and the patience to fault trace these circuits?
