P1015 Dodge Code - Reductant Control Module Sensor Serial Communication Circuit Low Voltage
Quick Answer
The P1015 diagnostic trouble code for Dodge vehicles refers to an issue with the Reductant Control Module Sensor Serial Communication Circuit, specifically indicating low voltage. Common causes include Faulty Sensor: A malfunctioning reductant sensor can cause communication issues with the Reductant Control Module, triggering the P1015 code, Wiring Issues: Damaged or corroded wiring harnesses connecting the sensor to the module can lead to low voltage in the communication circuit, Loose Connections: Loose or poor connections between the sensor and module can disrupt communication and trigger the code. 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 P1015 Dodge Description
The P1015 diagnostic trouble code for Dodge vehicles refers to an issue with the Reductant Control Module Sensor Serial Communication Circuit, specifically indicating low voltage. This code typically signifies a problem with the communication between the Reductant Control Module (RCM) and the sensor, which is responsible for monitoring the level of reductant (such as diesel exhaust fluid) in the vehicle's emissions system. When the voltage in the communication circuit drops below the specified threshold, it triggers the P1015 code.
Common Causes of P1015 Dodge
- Faulty Sensor: A malfunctioning reductant sensor can cause communication issues with the Reductant Control Module, triggering the P1015 code.
- Wiring Issues: Damaged or corroded wiring harnesses connecting the sensor to the module can lead to low voltage in the communication circuit.
- Loose Connections: Loose or poor connections between the sensor and module can disrupt communication and trigger the code.
- Reductant Control Module Malfunction: An issue with the Reductant Control Module itself, such as a faulty component or internal fault, can cause the P1015 code.
Symptoms of P1015 Dodge
- Check Engine Light: The most common symptom associated with the P1015 code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Reduced Power: The vehicle may experience reduced power or acceleration due to the malfunctioning reductant system.
- Decreased Fuel Efficiency: A drop in fuel efficiency may occur as a result of the P1015 code triggering the vehicle to operate in a less efficient mode.
- Increased Emissions: The vehicle may produce higher emissions than usual, potentially leading to environmental concerns or failing emissions tests.
How to Fix P1015 Dodge
- Diagnose the Issue: Use a diagnostic scanner to retrieve the specific trouble code (P1015) and perform additional testing to pinpoint the exact cause of the communication circuit low voltage.
- Check Wiring and Connections: Inspect the wiring harnesses, connectors, and terminals related to the reductant sensor and control module for damage, corrosion, or loose connections.
- Test Sensor Functionality: Verify the functionality of the reductant sensor by testing its voltage output and ensuring it is providing accurate readings to the control module.
- Repair or Replace Components: Repair or replace any damaged wiring, connectors, or faulty components identified during the diagnostic process.
- Clear Codes and Test Drive: Clear the trouble codes from the vehicle's computer system, reset any adaptations, and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P1015 Dodge
The typical repair costs for addressing a P1015 code on a Dodge vehicle can vary depending on the specific cause of the issue and the extent of repairs needed. In general, the cost of parts such as a new reductant sensor, wiring harnesses, or control module components can range from $100 to $500 or more, depending on the quality and brand of the parts.
