P1406 Dodge Code - EGR System Pintle Position Error
Quick Answer
The P1406 diagnostic trouble code (DTC) for Dodge vehicles refers to an error in the Exhaust Gas Recirculation (EGR) system pintle position. Common causes include Faulty EGR Valve: The EGR valve itself may be faulty, causing the pintle position error, Clogged EGR Passage: Accumulated carbon deposits can clog the EGR passage, preventing proper operation, Electrical Issues: Wiring harness issues, damaged connectors, or a faulty ECM can disrupt communication with the EGR system. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P1406 Dodge Description
The P1406 diagnostic trouble code (DTC) for Dodge vehicles refers to an error in the Exhaust Gas Recirculation (EGR) system pintle position. The EGR system is responsible for recirculating a portion of the exhaust gas back into the engine's cylinders to reduce nitrogen oxide emissions and improve fuel efficiency. The pintle position error indicates that the EGR valve is not functioning properly, leading to potential performance issues and emissions problems.
Common Causes of P1406 Dodge
- Faulty EGR Valve: The EGR valve itself may be faulty, causing the pintle position error.
- Clogged EGR Passage: Accumulated carbon deposits can clog the EGR passage, preventing proper operation.
- Electrical Issues: Wiring harness issues, damaged connectors, or a faulty ECM can disrupt communication with the EGR system.
- Vacuum Leaks: Leaks in the vacuum system can affect the EGR valve's operation, leading to the pintle position error.
Symptoms of P1406 Dodge
- Check Engine Light: The most common symptom associated with the P1406 code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Rough Idling: The engine may experience rough idling or stalling due to improper EGR valve operation.
- Reduced Fuel Efficiency: A malfunctioning EGR system can lead to decreased fuel efficiency, resulting in more frequent trips to the gas station.
- Engine Misfires: The engine may misfire or hesitate during acceleration, affecting overall performance.
How to Fix P1406 Dodge
- Diagnostic Testing: Use a scan tool to read the DTC and perform a comprehensive diagnostic test to pinpoint the exact cause of the P1406 code.
- EGR Valve Inspection: Inspect the EGR valve for any signs of damage or corrosion. Clean or replace the valve as needed.
- Check EGR Passage: Check the EGR passage for clogs or restrictions. Clean out any debris that may be obstructing the flow of exhaust gas.
- Repair Electrical Issues: Inspect the wiring harness, connectors, and ECM for any faults. Repair or replace damaged components to ensure proper communication with the EGR system.
- Clear DTC: After completing the repairs, clear the DTC from the ECM's memory and test drive the vehicle to verify that the issue has been resolved.
Cost to Fix P1406 Dodge
The cost of repairing a P1406 EGR system pintle position error can vary depending on the specific cause of the issue and the labor rates in your area. On average, the repair cost for this code can range from $200 to $500, including parts and labor. However, it's important to note that diagnostic time and labor rates at auto repair shops can fluctuate based on factors such as location, vehicle make and model, and engine type.
