Fix code P0471 Dodge Ram, exhaust manifold pressure sensor, Ram trucks
Chrysler has issued a technical service bulleting (TSB) #25-001-12 relating to trouble code P0471 that may set under certain freezing conditions. The exhaust manifold pressure sensor may accumulate condensation and freeze which causes the sensor to crack. That will set a P0471 Exhaust pressure sensor 1 performance trouble code. Chrysler has a redesign part and kit to eliminate the problem. Order the new sensor #68002442AA and the insulating kit #68175216AA from the dealer.
The fix applies to 2010-12 Ram 2500 and Ram 3500 pickups and Ram 3500/4500/5500 cab chassis equipped with the Cummins 6.7 diesel engine
