Code U0171 RAM Description
The U0171 diagnostic trouble code (DTC) indicates that the vehicle's onboard computer has lost communication with the up-front right satellite acceleration sensor. This sensor is responsible for detecting changes in acceleration and deceleration, providing crucial data for the vehicle's stability control system. When communication with this sensor is lost, it can lead to a variety of issues that affect the vehicle's performance and safety.
Common Causes of U0171 RAM
- Faulty up-front right satellite acceleration sensor.
- Wiring or connection issues between the sensor and the vehicle's computer.
- Corrosion or damage to the sensor's connectors.
- Electronic control module (ECM) software issues affecting sensor communication.
- Electrical system malfunctions or shorts affecting sensor signals.
Symptoms of U0171 RAM
- Illumination of the traction control or stability control warning light on the dashboard.
- Decreased traction or stability while driving, especially during sudden maneuvers.
- Increased stopping distance or difficulty braking in emergency situations.
- Erratic behavior of the vehicle's stability control system, such as unintended activation or deactivation.
How to Fix U0171 RAM
- Begin by conducting a thorough visual inspection of the up-front right satellite acceleration sensor and its wiring harness for any visible damage, corrosion, or loose connections.
- Use a diagnostic scan tool to retrieve and clear the U0171 code from the vehicle's computer memory.
- Test the sensor's functionality by checking its output signals with a multimeter or oscilloscope.
- If the sensor is found to be faulty, replace it with a new OEM or high-quality aftermarket sensor.
- After installing the new sensor, clear the DTC from the vehicle's computer memory and perform a test drive to ensure that the code does not reappear.
Cost to Fix U0171 RAM
The typical repair costs for addressing a U0171 code can vary depending on the specific cause of the issue and the vehicle's make and model. In general, replacing a faulty up-front right satellite acceleration sensor can range from $150 to $300 for the part alone. Labor costs for diagnosis and repair can add an additional $100 to $200, bringing the total repair estimate to approximately $250 to $500.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
- Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
- Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
- Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
