P1405 Chrysler Code - EGR Solenoid High

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 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.

What it means: P1405 Chrysler indicates EGR Solenoid High.
Common causes: Common causes include Faulty Exhaust Gas Recirculation (EGR) Valve, Faulty Exhaust Gas Recirculation Valve Solenoid, Exhaust Gas Recirculation valve carbon blockage.
Severity: High - diagnose this code as soon as possible.
Can I drive?: Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1405 Chrysler 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 P1405 Chrysler Code

1. What does the OBDII code P1405 mean on a Chrysler vehicle?

P1405 indicates an issue with the Exhaust Gas Recirculation (EGR) solenoid circuit, specifically that it is experiencing a high voltage condition.

2. What are the common symptoms of a P1405 code in a Chrysler?

Symptoms may include the Check Engine Light turning on, rough idling, reduced fuel efficiency, engine hesitation, or increased emissions.

3. What causes the P1405 code to appear in a Chrysler?

Common causes include a faulty EGR solenoid, damaged wiring or connectors in the EGR circuit, or a malfunctioning Powertrain Control Module (PCM).

4. Can I drive my Chrysler with a P1405 code?

While the vehicle may still be drivable, it is not recommended as it can lead to increased emissions, poor performance, and potential damage to other components.

5. How do I diagnose the P1405 code in a Chrysler?

Start by inspecting the EGR solenoid, its wiring, and connectors for damage or corrosion. Use a multimeter to test the solenoid and check the circuit voltage.

6. How can I fix the P1405 code in a Chrysler vehicle?

Repairs may involve replacing the EGR solenoid, repairing or replacing damaged wiring or connectors, or reprogramming or replacing the PCM if necessary.

7. How much does it cost to repair a P1405 code in a Chrysler?

Costs can vary, but replacing the EGR solenoid typically ranges from $100 to $300, including parts and labor.

8. Can a clogged EGR valve cause the P1405 code in a Chrysler?

No, a clogged EGR valve usually triggers different codes. P1405 specifically relates to the EGR solenoid circuit voltage being too high.

9. Will clearing the P1405 code fix the problem?

Clearing the code will turn off the Check Engine Light temporarily, but if the underlying issue isnâ€™t fixed, the code will reappear.

10. How can I prevent a P1405 code in the future?

Regular maintenance, including checking the EGR system and keeping electrical connections clean and secure, can help prevent this code from occurring.
