Dodge Ram Wagon B150 Problems
RepairPal has identified the most common problems with the Dodge Ram Wagon B150 based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
An intermittent connection in the crank position sensor wire connector can cause poor engine performance or the engine may crank but not start.
On the 3.9L V6 and 5.2L V8, rerouting the ignition coil wire and spark plug wires can help solve a misfire and/or surge problem that occurs at approximately 45 mph. A service bulletin was published that outlines the specifics of the repair. It states the rerouting procedure should be performed before other repairs are done for misfires, surging or spark knock.
Some vehicles may exhibit excessive fuel gauge movement while turning corners. Our technicians tell us the repair involves replacing the fuel pump module assambly.
The engine may exhibit excessively high oil pressure at cold start up. This may lead to distortion of the oil filter case. Inspect the oil filter case for any signs of distortion. If the case is distorted, Connect an oil pressure gauge to the engine and start the engine while observing the readings. If the pressure reads above 80 psi, replace the oil pump.
A clogged or restricted transmission fluid cooler system can be the cause of reoccurring transmission failures. Our technicians tell us that if your transmission has failed due to lack of lubrication the transmission fluid cooler and lines should be thoroughly inspected for restrictions.
Leak detection pump failure can be caused by the internal diaphragm switch sticking, or in some cases, contamination from debris or carbon particles from vapor canister. If black carbon particles are present in the LDP, replace vapor canister in addition to LDP. The purge solenoid should also be checked for debris or carbon contamination and replaced as necessary. All evap system hoses are subject to cracking and splitting causing leaks, Inspect hoses carefully. In cases of contamination from carbon particles or debris, all hoses and tubes must be blown out with compressed air to remove contaminates.
The AC/heater (HVAC) system may unexpectedly switch to the defrost mode when accelerating. This system is operated by engine vacuum and should be inspected for any vacuum leaks if this problem develops. There is also a revised vacuum check valve available to address this concern.
