2009 dodge Big Horn Ram 5.7 hemi oil pressure sensor

Brian Patterson

Asked by Apr 29, 2016 at 10:04 AM about the 2009 Dodge Ram 1500 ST Crew Cab 4WD

Question type: Maintenance & Repair

4 months ago I had an oil pressure sensor replaced on my
2009 dodge 4x4 5.7 liter hemi. It had 78k miles and now
here at the end of April the check engine light illuminates
with a low oil pressure code.  I am going to take it back to
the mechanic but would love some input about the sensor
or possible other problems it may be??

The safe method is to check your oil pressure with a high quality GaugePSI tool , then inspect and diagnose the sender / sensor.

Has this vehicle been well maintained. If no it is possible that sludge or other debris is getting into the oil pressure sender causing it to give a false reading. An ordinary pressure gauge and proper fittings to get it connected to where the pressure sender goes is the best way to get a fairly accurate reading on the oil pressure. It is also possible that the replacement sender went bad.

Bad roller tip on a lifter caused by MDS system. Get it checked by dodge asap. they have the software and know the symptoms. I just went through this. had to buy a motor. what a nightmare!
