My 06 is throwing a P0089 code. The fuel pressure sensor was previously replaced, so after doing some research I thought I might check the PEM (Pump Elec. Module). Problem is, I can't locate it. There is a bracket on the R. side of the fuel tank forward of the rear axle that looks like it should be mounted there but it's not. I looked under the rear seat, and not there either. Any ideas anyone? Thanks!

 

Looks like the PEM was located in the cargo hold opposite the battery.

 

i personally have never replaced anything other than the fuel pressure sensors and fuel pumps on those cars. you might want to diagnose it further before replacing expensive parts
