What is the P0871 code in a Ram 2500?

The P0871 code in a Ram 2500 is a diagnostic trouble code that indicates a problem with the transmission fluid pressure sensor circuit. This code specifically refers to Circuit A, which means there is an issue with the electrical connection or signal related to the transmission fluid pressure sensor.

It is important to address this code promptly, as it can cause various transmission-related issues such as harsh shifting, slippage, or even complete transmission failure if left unattended.

Possible Causes of the P0871 Code

There are several potential causes for the P0871 code in a Ram 2500:

1. Faulty transmission fluid pressure sensor: The sensor itself may be malfunctioning, providing incorrect readings or no readings at all.

2. Wiring or connector issues: Damaged or loose wiring or connectors can disrupt the signal between the sensor and the vehicle's engine control unit (ECU).

3. Low transmission fluid level: Insufficient fluid levels can affect the pressure readings and trigger the P0871 code.

4. Blocked transmission fluid passages: If there is a buildup of debris or contaminants in the transmission fluid passages, it can lead to pressure abnormalities and trigger the code.

How to diagnose the P0871 code?

To diagnose the P0871 code in a Ram 2500, follow these steps:

1. Scan the vehicle: Use an OBD-II scanner to retrieve the trouble codes and confirm the presence of the P0871 code.

2. Check the transmission fluid level and condition: Ensure that the transmission fluid level is within the recommended range and inspect it for any signs of contamination or degradation.

3. Inspect the wiring and connectors: Examine the wiring and connectors related to the transmission fluid pressure sensor for any damage, loose connections, or corrosion.

4. Test the transmission fluid pressure sensor: Measure the voltage output of the sensor using a multimeter and compare it to the manufacturer's specifications.

How to fix the P0871 code in a Ram 2500?

To fix the P0871 code in a Ram 2500, consider the following steps:

1. Replace the transmission fluid pressure sensor: If the sensor is determined to be faulty, replace it with a new one to ensure accurate readings.

2. Repair or replace damaged wiring or connectors: If any issues are found with the wiring or connectors, repair or replace them as necessary to restore proper electrical connections.

3. Check and refill the transmission fluid: If the fluid level is low, top it up to the recommended level. If the fluid is contaminated, perform a complete fluid flush and refill.

4. Clear the codes and test drive: After performing the necessary repairs, clear the trouble codes using an OBD-II scanner. Take the vehicle for a test drive to ensure that the P0871 code does not return and that the transmission operates smoothly.
