My charger has 216k miles on it. I had the P0524 Engine oil pressure too low code coming on. First time it did that was last year when dealer said leaking water pump dripped on connector and it damages the sensor. I replace pump and sensor and it was good for a year. Now it is back again. I do not want to believe the oil pressure sensor is bad again. Watching the digital readout of oil pressure, it typically reads around 50-55 just driving and will increase if I put my foot on it. At lights, just idling waiting for green light it drops to about 20. I do not believe that to be too low and the red oil lamp never comes on. I am wondering if the PCM needs to be reset.

to the following Diagnostic Trouble Code (DTC):
· P0524 - Engine Oil Pressure Too Low
DIAGNOSIS:

TechCONNECT, verify all engine systems are functioning as designed. If other DTC's are
present record them on the repair order and repair as necessary before proceeding further
with this bulletin.
Now the 2007 charger is not on this TSB but wonder if the issue is the same. I run synthetic oil and never had an issue and had a shop change my oil and put AMSOIL synthetic in it. As long as it is 5W-20, should be good. I will most likely swap out the oil pressure sensor since the part is reasonable from MOPAR. The job is a bit of a pain. Anyone else have this issue? I have seen it on the truck forum.

 

the 07 charger is part of this bulletin. what is your build date? pm me the last 8 of your vin and I can check it. if its in the date listed have the pcm programming level inspected. if its not the most recent flash...have it reprogrammed. the cost will be approx. 1 hour labour.

 

Last 8 sent.

 

your build date is 26 sept 2006 so that tsb applies. call a few dealers for quotes for pcm programming. tell them you need a pcm flash update to correct a problem as per the technical service bulletin#
18-003-08 - Flash: MIL Illumination Due To Diagnostic Trouble Code P0524


The dealer will connect to the scan tool and see what level of programming is in the pcm and update if required. At this point you do not need a diagnosis...just the flash. If the flash takes care of it and it probably will, your golden. If it doesn't...then consider diagnosis.

 

Thanks Primem,

I appreciate you decoding it for me. I will give the dealer a call.
