Code U0170 RAM Description
The U0170 diagnostic trouble code (DTC) indicates that the vehicle's onboard computer has lost communication with the up-front left satellite acceleration sensor. This sensor is responsible for detecting changes in acceleration and deceleration, providing crucial data for the vehicle's stability control and traction control systems. When communication with this sensor is lost, it can lead to a variety of issues that affect the vehicle's performance, safety, and overall drivability.
Common Causes of U0170 RAM
- Faulty up-front left satellite acceleration sensor.
- Damaged wiring or connectors leading to the sensor.
- Corrosion or moisture intrusion in the sensor's connections.
- ECU software issues affecting communication with the sensor.
- Physical damage to the sensor due to impact or improper installation.
Symptoms of U0170 RAM
- Illumination of the traction control or stability control warning light on the dashboard.
- Erratic or unpredictable handling, especially during acceleration or braking.
- Reduced traction or stability when driving on slippery or uneven road surfaces.
- Decreased fuel efficiency due to compromised performance of the stability control system.
- Possible limp mode activation, limiting the vehicle's speed and performance to protect the drivetrain.
How to Fix U0170 RAM
- Begin by conducting a thorough visual inspection of the up-front left satellite acceleration sensor and its wiring harness for any signs of damage, corrosion, or loose connections.
- Use a diagnostic scan tool to retrieve the specific fault codes stored in the vehicle's ECU and verify that the issue is related to the lost communication with the sensor.
- If the sensor is found to be faulty, replace it with a new OEM or high-quality aftermarket sensor, ensuring proper installation and calibration.
- Clear the DTCs from the ECU's memory using the diagnostic scan tool and perform a test drive to verify that the issue has been resolved.
- If the problem persists, further diagnostic testing may be required to identify any underlying issues with the ECU or wiring harness.
Cost to Fix U0170 RAM
The cost of repairing the U0170 DTC related to lost communication with the up-front left satellite acceleration sensor can vary depending on the specific cause of the issue and the vehicle's make and model. In general, the cost of replacing the sensor itself can range from $100 to $300, while labor costs for diagnosis and repair can add an additional $100 to $200. Overall, the total repair cost for this issue may fall within the range of $200 to $500, but it's advisable to check with local auto repair shops for more accurate estimates based on your vehicle's specific requirements. Keep in mind that labor rates can vary widely based on location, shop rates, and the complexity of the repair.

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.
Frequently Asked Questions about U0170 RAM Code
What does the OBDII code U0170 mean for my RAM vehicle?
U0170 indicates that there is a lost communication issue with the up-front left satellite acceleration sensor, which affects the vehicle's ability to read acceleration data accurately.
What are the common symptoms of a U0170 code?
Common symptoms include warning lights on the dashboard, issues with traction control or stability control systems, and possible erratic handling or performance issues.
What could cause the U0170 code to trigger?
The code can be triggered by a faulty satellite acceleration sensor, damaged wiring or connectors, or issues with the vehicle's main control module.
How can I diagnose the U0170 code?
Start by using an OBD-II scanner to confirm the code. Then, inspect the satellite acceleration sensor and its wiring for damage, corrosion, or loose connections. Testing the sensor's operation may also be necessary.
Is it safe to drive my RAM with a U0170 code?
While it might be safe to drive, you may experience handling issues or decreased stability. It's advisable to have the vehicle inspected and repaired to ensure optimal performance and safety.
Can I repair the U0170 code myself?
If you have automotive repair experience, you can check the wiring and connections or replace the sensor. However, if you're unsure, it's best to consult a professional mechanic.
What is the cost range for repairing a U0170 code?
Repair costs can vary widely depending on whether it’s just a wiring issue or if the satellite acceleration sensor needs to be replaced. Expect to pay anywhere from $100 to $500 or more, depending on labor and parts.
How does a faulty satellite acceleration sensor affect my vehicle?
A faulty satellite acceleration sensor can lead to poor vehicle stability, inaccurate traction control, and potentially unsafe driving conditions, especially in adverse weather.
Will clearing the U0170 code fix the problem permanently?
Clearing the code may temporarily remove the warning, but if the underlying issue (like a faulty sensor or wiring problem) is not addressed, the code will likely reappear.
