2019 Jeep Compass Oil Pressure Issues
Discussion
Hi all
Well this one has got me at a bit of a dead end with my only other option being to take it to a specialist (££££!!!!).
2019 Jeep Compass 1.6 diesel (FIAT engine), had service light come on, read error code as P0521 engine oil pressure sensor/switch circuit range/performance.
So have replaced the oil pressure switch and done oil & filter change and still have the issue.
The car is about 50% down on power (accelerating from 20mph-50 is very sluggish) and not sure if this is linked but sometimes when you press ignition button once (car ignition comes on), then again without the clutch down the car starts up (instead of then turning off as the clutch isn't down). This happens about 50% of the time and works fine the other 50%.
There is also the oil change required light which also will not reset (despite trying pedal sequence etc to reset)
My neighbour works in a "regular" garage and we used his more in depth snap on scanner tool to check the car is recognizing when the clutch is up/down/halfway (which it is), and to try and see if any other codes or if we can clear the code/oil change reminder, which it couldn't.
My thinking is, maybe the car is in some kind of "limp" mode due to thinking there's either an oil pressure issue, or that the oil change is overdue. There is little info online about these engines but essentially i believe it's the FIAT lump as this is when FIAT owned Jeep, still is hard to get any more info.
Two mechanics I know and have spoken to have never seen a car start up without the clutch pedal pressed like this.
Any ideas chaps?
thanks
John

As far as the clutch goes, I can only imagine that the ECU has decided the clutch signal is unreliable.
Can't advise on the other issues, but it would be extraordinary for an engine to go into limp mode without showing codes explaining why.
If you have any doubt about the oil pressure, get it checked mechanically. Most electronic/electrical problems will wait while you diagnose them, but if the oil pressuse is low that could escalate fast.

Hi John did you get the oil pressure switch limp mode sorted? mine has just done the same last week. I had the jeep serviced on Sunday & the two mechanics and snap-on diagnostic pad could not clear the code. our jeep also has developed that odd no clutch down start. its very baffling .
Going to have to look at jeep main dealer as the lack of power / limp mode is troubling.
