SOURCE: where is the oil sending unit on 2006 hummer h2

Just finished changing one out tonight on a 2004 H2 with 6.0L. It's on the back of the block, behind the intake manifold and beside the distributer. There is a wire harness connector on one side and a manifold bolt on the other so it's a tight space. Use a 12 point thin-wall deep socket (a 6 point deep impact socket won't clear). Then slid a 6" long piece of hose over the new unit to get started in the hole, wasn't enough room to get hands in to install without the hose.

SOURCE: The reduce engine power message

The Powertrain Control Module (PCM) is shutting down your throttle body control for some reason and limiting how much throttle you can apply. The only way to find out why it is doing this is to scan the PCM for Diagnostic Test Codes (DTCs) and diagnose any existing codes accordingly. It is very likely to be caused by a fault in your throttle position sensor or accelerator pedal position sensor circuits.

There is a Technical Service Bulletin (TSB) for your vehicle which covers a known problem with reduced engine power and sets DTC P2138. The known problem is that the Accelerator Pedal Position (APP) sensor circuits are being infiltrated by water intrusion into a connector and causing erratic voltage readings at the PCM. It is TSB reference # 07-06-04-019D
