I feel like I'm gonna annoy you guys if I keep posting threads, in that case,
anyways, I have a friend with an '06 CRD liberty like mine who came to me to scan his codes and help him. I pulled three codes:
P0234-Turbo Boost Limit Exceeded
P0108-Inlet Air Pressure Sensor Voltage Too High
P0093-Fuel System Leak
He complained about the car going into limp a couple times and such. The jeep takes an unusually long time to fire up (compared to mine). And when looking under the hood while someone is pushing the accelerator, the hoses seem to expand more than usual.
I know how to check the fuel system for air. I'm curious to know what's up with the overboost? I want to start with checking the MAF sensor MAP sensor and the sensor on the airbox next to the MAF. Then the turbo hoses for cracks or something more unusual than oil. I assume after doing some research that I should check the vacuum system? since the turbo doesn't have a wastegate, what could be stuck closed?
