Engine Code 164 32 1

[Paul Bowers]

Coach has been running great, getting it ready for the summer.  Went to start and engine would turn over, but it would not start.  Checked codes and the Engine Diagnostics Code captured 164-32-1, INJ ACT PSR OUT OF RNG.  Assume this mean Injection Actuation Pressure Out of Range.

Is this a sensor problem that can simply be fixed, or is this possibly a major repair?

Any information would be greatly appreciated before calling the wrecker and tow to CAT.
