13 Grand Cherokee 3500 rpm limit
13 Grand Cherokee with 120k just had the oil changed. Shortly after, the check engine light came on and I was limited to 3500 rpms. If I restart, the light stays on but I'm no longer limited to 3500. After a few start cycles, the light goes off and whole thing repeats. After driving like this for a few weeks, it appears to only happen during acceleration. It doesn't matter if the light is on or off, I can reproduce the error. During this time, I had the oil changed again, same thing. I took it to the dealer and they changed an oil sensor behind the manifolds for $700. Same thing. Took it back to the dealer and they changed the oil filter....again. NAPA vs Chrysler. Same thing. Took it back to the dealer, they were also able to reproduce the error, but don't seem to know how to correct it. This is my sixth jeep, put 200k+ on each and happy with all of them. Before I take this to another dealer, are there any suggestions out there on a possible cause?
