Troubleshooting a P0871 Code on a 6.7 Cummins Engine

P0871 is an OBD-II trouble code indicating a problem with the transmission fluid pressure sensor/switch “A” circuit. This code is specific to Dodge Ram trucks with 6.7L Cummins diesel engines, and indicates that the transmission pressure sensor or switch has failed or is malfunctioning. The code will be stored in the engine control module (ECM) and may be accompanied by other transmission codes as well. To fix this issue, the faulty part must be located and replaced.

Understanding the Code P0871 Code 6.7 Cummins

Automobiles are complex machines, and understanding their codes and how they work can help to diagnose problems. The P0871 code 6.7 Cummins is an OBD-II diagnostic trouble code (DTC) that refers to a problem with the transmission control module (TCM). It is a generic code that applies to all makes and models of vehicles equipped with an OBD-II system. This code can be triggered by a variety of issues, including low transmission fluid levels, faulty sensors, or even a loose wiring connection.

Symptoms of the Code

When the P0871 code 6.7 Cummins is triggered, the vehicle will typically display one or more of the following symptoms: engine hesitation or stalling when shifting gears, poor fuel economy, delayed shifts, harsh shifts, slipping out of gear while driving, or even complete transmission failure in some cases. It is important to note that these symptoms may be caused by other issues as well, so it is important to have a professional mechanic diagnose and repair any problems before proceeding with repairs.

Troubleshooting the Issue

In order to properly troubleshoot any issue related to the P0871 code 6.7 Cummins DTC, it is important to follow a step-by-step guide for diagnosis and repair. The first step should always be to check for any current codes stored in the vehicle’s ECU memory using an OBD-II scanner tool. This will help to narrow down the possible causes of the code being triggered and make diagnosing and repairing the issue easier.

Once any current codes have been identified and addressed, it is important to visually inspect all wiring connections related to the transmission control module (TCM) for signs of damage or loose connections. If any are found then they should be replaced as needed before proceeding with further diagnosis and repair steps. Once this has been done it is recommended that you check for proper operation of all sensors related to the transmission system including fluid level sensors as well as speed sensors in order for them to be functioning correctly before continuing on with further repairs.

Finally, if no other issues are found then you may need to replace either your TCM itself or other components such as solenoids if they have become worn out over time due to use or wear and tear from normal operation. In some cases you may also need to replace your entire transmission in order for your vehicle’s P0871 code 6 .7 Cummins DTC issue to be resolved correctly.

Common causes of this issue can include low transmission fluid levels due too leaks in hoses or seals; faulty sensors; worn out solenoids; loose wiring connections; or even a bad TCM itself which could cause intermittent shifting problems when driving your car at higher speeds or under heavy load conditions such as hill climbing scenarios where more torque is required from your engine/transmission combination than usual load conditions would require normally on flat terrain roads surfaces where less torque would be needed under normal driving conditions/scenarios..

Preventative Maintenance Tips

It’s always best practice when owning an automobile equipped with an OBD-II system such as those found on vehicles with engines like those found in most Dodge Ram pickups equipped with P0871 Code 6 .7 Cummins engines that regular maintenance like changing fluids and filters regularly should be done at least twice per year depending on how often you use your vehicle for hauling heavy loads over long distances which can put extra strain on your car’s engine/transmission combo leading them both needing more frequent maintenance than if you only drove around town every now and then without putting much strain on them from heavy loads being towed behind them regularly..
Regularly inspecting belts and hoses under hood should also be done at least once per year especially during cold winter months where road salt can corrode metal parts like hoses leading them needing replaced earlier than normal due corrosion buildup over time if untreated..

Professional Services To Consider

For those who don’t feel comfortable performing their own preventative maintenance tasks it might be worth considering taking their vehicle into a qualified automotive specialist who offers services like oil changes which can help keep engine/transmission combos running efficiently by replacing dirty oil which has broken down over time due use preventing premature wear on internal components inside both engine/transmission combos which could lead serious expensive repairs down line if left unchecked.. Additionally flushing radiators & coolant systems at least once every 5 years can help maintain proper cooling temperatures inside engine bays during hot summer months where temperatures tend rise significantly inside cars leading automotive components like radiators & cooling systems needing serviced more often than usual due increased heat buildup inside cars leading radiators needing flushed more frequently than normal in order keep cooling temperatures regulated inside car’s engine bay preventing overheating related issues from occurring unexpectedly while driving causing major headaches down line if left untreated properly..
