P1019 Dodge Code - Reductant Control Module Sensor Communication Voltage Supply Circuit High Voltage
Quick Answer
The P1019 diagnostic trouble code for Dodge vehicles refers to a problem with the Reductant Control Module Sensor Communication Voltage Supply Circuit being too high. Common causes include Faulty Reductant Control Module: The issue may stem from a malfunction within the Reductant Control Module itself, causing communication errors with the sensors, Wiring Harness Issues: Damaged or corroded wiring harness connections can disrupt the voltage supply circuit, leading to high voltage readings, Sensor Malfunction: A faulty sensor within the SCR system can also trigger this code by providing incorrect data to the Reductant Control Module. 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 P1019 Dodge Description
The P1019 diagnostic trouble code for Dodge vehicles refers to a problem with the Reductant Control Module Sensor Communication Voltage Supply Circuit being too high. This code is typically associated with diesel engine vehicles that utilize a selective catalytic reduction (SCR) system to reduce emissions. The Reductant Control Module is responsible for monitoring and controlling the levels of urea solution (AdBlue) injected into the exhaust stream to break down harmful nitrogen oxide emissions into harmless nitrogen and water vapor.
Common Causes of P1019 Dodge
- Faulty Reductant Control Module: The issue may stem from a malfunction within the Reductant Control Module itself, causing communication errors with the sensors.
- Wiring Harness Issues: Damaged or corroded wiring harness connections can disrupt the voltage supply circuit, leading to high voltage readings.
- Sensor Malfunction: A faulty sensor within the SCR system can also trigger this code by providing incorrect data to the Reductant Control Module.
- Software Glitch: Occasionally, a software glitch within the vehicle's control module can cause communication errors with the Reductant Control Module.
- Electrical System Problems: Issues with the vehicle's electrical system, such as a weak battery or alternator, can also impact the voltage supply circuit.
Symptoms of P1019 Dodge
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Fuel Efficiency: A malfunctioning Reductant Control Module can lead to inefficient dosing of the urea solution, resulting in decreased fuel efficiency.
- Poor Performance: The engine may experience reduced power output or hesitation during acceleration due to improper emissions control.
- Increased Emissions: A faulty Reductant Control Module can lead to increased emissions output, potentially causing the vehicle to fail emissions tests.
- Exhaust Odor: In extreme cases, a malfunctioning SCR system may result in the emission of unpleasant odors from the vehicle's exhaust.
How to Fix P1019 Dodge
- Diagnose the Issue: Use a diagnostic scanner to retrieve the specific code and perform a thorough inspection of the Reductant Control Module, sensors, and wiring harness for any visible damage or faults.
- Replace Faulty Components: Replace any malfunctioning sensors, wiring harness connections, or the Reductant Control Module itself if necessary.
- Clear Error Codes: After completing repairs, clear the error codes and reset the vehicle's onboard computer system to see if the issue has been resolved.
- Test Drive: Take the vehicle for a test drive to ensure that the check engine light does not reappear and that the system is functioning properly.
- Emission Test: If necessary, perform an emissions test to verify that the SCR system is now operating within acceptable parameters.
Cost to Fix P1019 Dodge
The cost of repairing a P1019 code for the Reductant Control Module Sensor Communication Voltage Supply Circuit High Voltage can vary depending on the extent of the issue and the specific components that need to be replaced. On average, the cost for parts and labor for this repair can range from $200 to $600. However, it's important to note that labor rates at auto repair shops can vary widely, typically ranging from $80 to $150 per hour. Additionally, the cost of parts, such as sensors or the Reductant Control Module, can also contribute to the overall repair bill. It's recommended to consult with a qualified mechanic or dealership to obtain a more accurate estimate based on your vehicle's make and model.
