P1406 RAM Code - EGR System Pintle Position Error

Quick Answer

The Exhaust Gas Recirculation (EGR) valve recirculates exhaust gas to the engine intake for increased efficiency, lower fuel consumption, and reduced NOx emissions. Common causes include Faulty Exhaust Gas Recirculation (EGR) Valve, Faulty Exhaust Gas Recirculation Valve Solenoid, Exhaust Gas Recirculation valve carbon blockage. 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.

What it means: P1406 RAM indicates EGR System Pintle Position Error.
Common causes: Common causes include Faulty Exhaust Gas Recirculation (EGR) Valve, Faulty Exhaust Gas Recirculation Valve Solenoid, Exhaust Gas Recirculation valve carbon blockage.
Severity: Moderate - service should be scheduled soon.
Can I drive?: The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P1406 RAM Description

The Exhaust Gas Recirculation (EGR) valve recirculates exhaust gas to the engine intake for increased efficiency, lower fuel consumption, and reduced NOx emissions. The valve changes the air's chemical makeup by adding exhaust gas, which dilutes the mixture and lowers combustion temperatures, resulting in less NOx production. The valve has two primary settings: open and closed, depending on the engine's power requirements. EGR valves can also improve combustion efficiency, reduce pumping losses, and decrease diesel knock at idle.
The Diagnostic Trouble Code (DTC) will be set when the Engine Control Module (ECM) detects EGR flow or movement when it is not expected.

Frequently Asked Questions about P1406 RAM Code

1. What does the OBDII code P1406 mean on a RAM vehicle?

P1406 on a RAM vehicle indicates an "EGR System Pintle Position Error," meaning the Exhaust Gas Recirculation (EGR) valve's position does not match the expected value determined by the engine control module (ECM).

2. What are the common symptoms of a P1406 code in a RAM?

Common symptoms may include poor engine performance, rough idling, reduced fuel efficiency, stalling, and the Check Engine Light illuminating.

3. What causes the P1406 code to appear on a RAM?

Potential causes include a faulty EGR valve, carbon buildup obstructing the EGR valve, wiring or connector issues in the EGR system, or a malfunctioning EGR position sensor.

4. How do I diagnose the P1406 code on a RAM?

Diagnose the issue by checking for carbon buildup in the EGR valve, testing the EGR position sensor, inspecting wiring and connectors for damage, and using a scan tool to validate the EGR valve's position readings.

5. Can I drive my RAM with the P1406 code active?

While it may be possible to drive temporarily, prolonged operation with a P1406 code can lead to reduced engine performance, increased emissions, and potential damage to other engine components.

6. How do I fix the P1406 code on my RAM?

Fixes may include cleaning or replacing the EGR valve, repairing damaged wiring or connectors, or replacing the EGR position sensor if it's faulty.

7. How much does it cost to repair the P1406 code on a RAM?

Repair costs can vary, but cleaning the EGR valve typically costs $50â€“$150, while replacing it may cost $200â€“$400 or more, depending on labor rates and parts prices.

8. What tools are needed to address the P1406 code on a RAM?

Youâ€™ll need a scan tool to read and clear codes, basic hand tools to remove the EGR valve, and possibly a multimeter for testing electrical components.

9. Can a clogged EGR valve cause the P1406 code in a RAM?

Yes, carbon buildup or clogging of the EGR valve can prevent it from moving to the correct position, triggering the P1406 code.

10. How can I prevent the P1406 code from reoccurring on my RAM?

Regular maintenance, such as cleaning the EGR valve and using high-quality fuel, can help prevent carbon buildup and reduce the likelihood of the P1406 code returning.
