Earlier today I hit a pretty aggressive bump on the highway, shortly afterwards the car had a loss in power and codes p116e and p0335 (maf sensor electrical/ crank position sensor respectively.) any ideas what can cause this?

Did you check the maf and crankshaft position sensors? most likely the bump dislodged the connectors?

Thanks for the reply— replaced the crank sensor with new continental unit, maf seemed okay. Drove and the car is driving significantly better but, the process somehow fried my frm and shorted my small disa valve. The codes persist and came back.

did you forget to disconnect the battery before working on the car?

I did, but my trunk closed, so I used cables and the front terminals to get the trunk popped open. Really confused because the car starts and idles really rough but smooths out very well in about a minute.

Bump!! I still have electrical issues after replacing the sensor, long crank start, and poor idle. Same codes afterwards, and my new FRM (yes its correct i checked) causes the center control panel light to flicker?

Bump still trying to figure it out
