We scanned the computer and have the following codes; P1004-Short Runner Valve Control Performance. We test both short and long runner valves and seemed to be working. We then noticed inside the upper plenum the valve solenoid moves and is sticky. We have determined that the upper intake unit should be replaced because the valves wore out causing plastic intake to wear out. We recommend a new upper intake assembly. We cannot get a new upper intake manifold from the dealer because they no longer make one. We did find a (Used) unit and we are having it shipped to us. After installing the used upper intake we drove the vehicle and madr sure the valves are opening and closing which they are. There are no code present at this time and only the 02 heater, 02 sensor, and the EVAP monitor have not run yet. These codes should clear with more miles driven on the vehicle.
COOLANT TEMPERATURE SENDER OR SENSOR – Remove & Replace – V8
FRONT BRAKES @ ___8___MM REMAINING REAR BRAKES @ __5___MM REMAINING
THERMOSTAT &/OR GASKET – Remove & Replace – V8
We scanned the computer and have the following codes: PO934-Line pressure sensor circuit low PO868-Line pressure low PO933-Hydraulic Pressure sensor range/Perf PO869-Line pressure high PO935-Hydraulic Pressure sensor circuit high ________All Transmission codes___________ PO456-Small EVAP leak-Needs a smoke test to diagnose. P2181-Cooling system Performance PO128-T-Stat Rationality For the last two codes we recommend a new thermostat and gasket. Then recheck operation. For the EVAP leak we recommend a smoke test be performed and advise. After we replaced the thermostat we ran the vehicle to operating temp but were receiving inaccurate temp readings. We checked the coolant temp sensor and found corrosion in the coolant temp sensor plug. We recommend replacing the coolant temp sensor and then performing a head gasket check to make sure the head gasket is not blown. After our test we have found that the head gaskets are not blown and the cooling system is operating correctly at this time.
