Vehicle: 2010 Dodge Grand Caravan, V6-3.3L, Flex Fuel, Automatic Transmission
Problem: The vehicle starts and runs fine, but after 40+ miles, it develops a very intermittent, quick stumble and sets p1128. At times, the customer has driven up over 100 miles and not set a code. The fuel system checked out okay. The tech also checked the wiring for the MAP, O2 & ECT sensors – all were good.
Problem: When this vehicle came into the shop, the DLC was on and the tech pulled DTCs C0460 – Steering Angle Sensor and C056D 39 – ECU Hardware Performance Internal Electronic Failure. The Tech performed the TSB 07-02-32-009 to update the EBCM and PSCM. After the flash, the Tech could not calibrate the steering sensor.
Vehicle: 2011 Chevrolet Malibu, L4-2.4L, Automatic Transmission
Problem: The vehicle was brought to the shop because the MIL was on and the engine ran rough and stalled. The technician checked the fuel pressure and it was within factory specifications. He was unable to keep the vehicle running long enough to see any difference in the camshaft timing “actual” versus “desired” PID. He also retrieved the numerous DTCs listed below.
Vehicle: 2003 Ford F-250, 4WD, Super Duty, 7.3L DSL Turbo V-8, VIN F
Problem: When applying the brakes with doors closed and engine running, the dash and speedometer lamps dim. When the door is open and the truck is running, the warning chime sounds when brakes are applied. The problem does not occur when the brake pedal is released.
Problem: The customer brought the car to the shop because, after starting the car, the TPMS light would flash for a minute then stay on continually. This would happen every drive cycle. The vehicle had stock steel wheels and hubcaps.
Problem: The customer’s concern was that engine would not idle after it had warmed up. The malfunction indication light was OFF. If the engine speed was held over 800-850 rpm, the engine would stay running.
Vehicle: 2014 Ford Fusion, FWD, L4-2.0L Turbo, Automatic Transmission
Problem: A DTC, U0401 (Invalid Data Received from ECM/PCM A) won’t clear from all modules after recent collision repairs were made. The scan tool also reported an ABS/TCS steering module message. The vehicle had been in a rear-end collision and the front bumper was damaged as well.
Problem: The car was a sublet from a body shop after they did repairs because the radio, turn signals, low beams and the low-speed wipers were inoperative. The steering column switches and front ECU had already been replaced.
Vehicle: 2007 Dodge Caravan, V6-3.3L, VIN R Automatic Transmission
Problem: This vehicle came to the shop because the engine would crank but not start and the MIL was on. The camshaft (CMP) and crankshaft (CKP) sensors had already been replaced but did not fix the problem.
