P1017 Dodge Code - Reductant Control Module Sensor Serial Communication Circuit Performance

Quick Answer

The P1017 diagnostic trouble code (DTC) for Dodge vehicles refers to an issue with the Reductant Control Module Sensor Serial Communication Circuit. Common causes include Faulty Sensor: The sensor itself may be defective or damaged, causing communication issues with the Reductant Control Module, Wiring Issues: Corrosion, fraying, or short circuits in the wiring harness connecting the sensor to the module can disrupt communication signals, Module Malfunction: The Reductant Control Module itself may be faulty, leading to a breakdown in communication with the sensor. 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 P1017 Dodge Description

The P1017 diagnostic trouble code (DTC) for Dodge vehicles refers to an issue with the Reductant Control Module Sensor Serial Communication Circuit. The Reductant Control Module is a crucial component in the Selective Catalytic Reduction (SCR) system, which helps reduce harmful emissions in the vehicle's exhaust gases. The sensor in question is responsible for monitoring the efficiency of the SCR system by measuring the levels of reductant (often a urea-based solution) being injected into the exhaust stream.

Common Causes of P1017 Dodge

  1. Faulty Sensor: The sensor itself may be defective or damaged, causing communication issues with the Reductant Control Module.
  2. Wiring Issues: Corrosion, fraying, or short circuits in the wiring harness connecting the sensor to the module can disrupt communication signals.
  3. Module Malfunction: The Reductant Control Module itself may be faulty, leading to a breakdown in communication with the sensor.
  4. Software Glitch: Occasionally, a software glitch in the vehicle's onboard computer can trigger the P1017 code by mistake.

Symptoms of P1017 Dodge

  1. Check Engine Light: The most common symptom associated with the P1017 code is the illumination of the Check Engine Light on the vehicle's dashboard.
  2. Reduced Fuel Efficiency: A malfunctioning SCR system can lead to decreased fuel efficiency as the engine may not be operating at its optimal performance levels.
  3. Increased Emissions: The vehicle may fail emissions tests or emit higher levels of pollutants due to the compromised SCR system.
  4. Engine Misfires: In severe cases, the engine may experience misfires or rough idling due to the incorrect reductant levels being injected into the exhaust stream.

How to Fix P1017 Dodge

  1. Diagnose the Issue: Use a diagnostic scanner to retrieve the specific trouble code and pinpoint the exact cause of the communication failure.
  2. Inspect Wiring: Check the wiring harness for any visible damage, corrosion, or loose connections. Repair or replace any faulty wiring as needed.
  3. Test Sensor: Test the sensor for proper functionality using a multimeter or oscilloscope to ensure it is sending accurate signals to the module.
  4. Check Module: Inspect the Reductant Control Module for any signs of damage or malfunction. Replace the module if necessary.
  5. Clear Codes: Once the repair is complete, clear the DTC and test drive the vehicle to ensure the issue has been resolved.

Cost to Fix P1017 Dodge

The cost of repairing a P1017 code can vary depending on the specific cause of the issue and the labor rates in your area. On average, you can expect to pay between $200 and $500 for parts and labor. Keep in mind that diagnostic time and labor rates can vary between auto repair shops, so it's advisable to get quotes from multiple sources before proceeding with the repair.
