U059E RAM Code - Invalid Data Received From NOX Sensor 'A'

Quick Answer

The U059E diagnostic trouble code (DTC) refers to "Invalid Data Received From NOX Sensor 'A'." This code indicates that there is a communication error between the engine control module (ECM) and the NOX sensor 'A.' The NOX sensor, also known as the nitrogen oxide sensor, is responsible for monitoring the levels of nitrogen oxide in the exhaust gases. Common causes include Faulty NOX Sensor: The most common cause of the U059E code is a malfunctioning or failed NOX sensor 'A.', Wiring Issues: Corrosion, damage, or loose connections in the wiring harness connecting the NOX sensor to the ECM can trigger this code, ECM Malfunction: A problem with the engine control module can prevent it from receiving or interpreting data from the NOX sensor correctly. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code U059E RAM Description

The U059E diagnostic trouble code (DTC) refers to "Invalid Data Received From NOX Sensor 'A'." This code indicates that there is a communication error between the engine control module (ECM) and the NOX sensor 'A.' The NOX sensor, also known as the nitrogen oxide sensor, is responsible for monitoring the levels of nitrogen oxide in the exhaust gases. This sensor plays a crucial role in ensuring that the vehicle meets emissions standards and operates efficiently.

Common Causes of U059E RAM

  1. Faulty NOX Sensor: The most common cause of the U059E code is a malfunctioning or failed NOX sensor 'A.'
  2. Wiring Issues: Corrosion, damage, or loose connections in the wiring harness connecting the NOX sensor to the ECM can trigger this code.
  3. ECM Malfunction: A problem with the engine control module can prevent it from receiving or interpreting data from the NOX sensor correctly.
  4. Exhaust System Leaks: Leaks in the exhaust system can lead to inaccurate readings from the NOX sensor, triggering the U059E code.

Symptoms of U059E RAM

  1. Check Engine Light: The most common symptom associated with the U059E code is the illumination of the check engine light on the vehicle's dashboard.
  2. Reduced Fuel Efficiency: A faulty NOX sensor can cause the engine to run less efficiently, leading to decreased fuel economy.
  3. Poor Engine Performance: The vehicle may experience rough idling, hesitation, or stalling due to inaccurate data from the NOX sensor.
  4. Failed Emissions Test: If the NOX sensor is not functioning correctly, the vehicle may fail emissions testing due to increased emissions levels.

How to Fix U059E RAM

  1. Diagnose the Issue: Use a diagnostic scanner to retrieve the specific trouble code and determine the cause of the communication error between the ECM and the NOX sensor 'A.'
  2. Inspect Wiring: Check the wiring harness for any signs of damage, corrosion, or loose connections. Repair or replace any faulty wiring as needed.
  3. Test NOX Sensor: Test the NOX sensor 'A' to ensure it is functioning correctly. Replace the sensor if it is faulty.
  4. Reset ECM: Clear the trouble code from the ECM's memory and reset the system to see if the issue persists.
  5. Verify Repair: After completing the repair process, retest the vehicle to ensure that the U059E code does not return, indicating that the issue has been resolved.

Cost to Fix U059E RAM

The cost of repairing the U059E code can vary depending on the specific cause of the issue and the labor rates in your area. Typically, the cost of replacing a NOX sensor can range from $200 to $500, including parts and labor. However, if the issue is related to wiring or ECM malfunction, the cost may be higher. It is advisable to consult a professional mechanic for an accurate diagnosis and cost estimate for repairing the U059E code. Keep in mind that labor rates can vary between different auto repair shops, so it's essential to inquire about specific rates in your area.
