Vehicle: 2011 Dodge Grand Caravan, V6-3.6L, Automatic Transmission

Mileage: 102,009

Problem: This vehicle was brought to the shop for a rough running engine and the Malfunction Indicator Light (MIL) on.

1a.jpgDetails: The first thing the technician did was to check for DTCs. There was only one – P054A. The DTC description for this code is: Cold Start Exhaust Camshaft Position Timing over advanced on Bank 1, Sensor #2.

Based on the DTC and some previously similar cases, the Tech-Assist consultant advised the tech to performed a relative compression test by scoping battery amperage with an amp clamp while cranking. This test quickly pinpointed the problem – one cylinder on bank 1 had low compression.

Confirmed Repair: The technician removed the Bank 1 valve cover and found a worn cam lobe (See image). He replaced camshaft and the related rocker arms. He cleared the DTC and test drove the vehicle. The problem was fixed!
