Urgent Cummins Engine Problem
After having a bad thermostat replaced by a local shop (OC Fleet Services) my Engine Codes would not clear. They could not clear the engine codes so today I took it to Cummins Cal-Pacific in Downey and they cleared 2 codes but could not clear the code for the Crank Case Pressure sensor. They suggested taking it to Cummins in Bloomington – so I limped up there with it late this afternoon. it would not go over 30 mph & 1700 rpm and the transmission would not up-shift or down-shift properly. I had to leave it there. They just called me and said that the Pressure Sensor is with in specifications and they put in a new one but it was still throwing that code. They tried to say the coach OEM wiring was at fault. At 65,000 miles – I don’t think so. They refused to pull the hatch to look at the wiring because it was too labor intensive! They said take it to a "Dealer" ????
This last summer I had Redlands put in that chip to improve performance and am wondering if it could have gone bad. Anyone else experience anything like this & what did you do to fix it?
