Title: CAT C9 Oil Pressure Sensor
Post by: jeffprupis on May 17, 2018, 05:49:24 PM

Currently in Victoria, BC getting ready to have a CAT Electric Fuel Pump installed to remedy an engine sure issue under the auspices of Dave Atherton. The facility has also identified a know fault in our Oil Pressure Sensor as well. This was identified by an ECM read fault code that states the pressure will default to 86% when faulty. Does anyone (Dave) know if this is discussed on the forum and where? TIA

The ECM will detect failure of the engine oil pressure sensor. The diagnostic lamp warns the
user about the status of the engine oil pressure sensor. The engine oil pressure related strategies
will be disabled in the event of a failure of the engine oil pressure sensor. A failure of the engine oil pressure sensor will not cause a shutdown of the engine or any horsepower change. I believe
I have posted this before on Ask Dave.  Dave Atherton Retired Cat Mechanic
