Code P2404 Dodge Description

The P2404 code for Dodge vehicles indicates a problem with the Evaporative Emission System Leak Detection Pump Sense Circuit. This system is responsible for detecting leaks in the vehicle's fuel vapor system, which helps reduce emissions. When this code is triggered, it means that the vehicle's onboard computer has detected a range or performance issue with the circuit that monitors the Leak Detection Pump. This can lead to increased emissions, reduced fuel efficiency, and potentially even failing an emissions test.

Frequently Asked Questions about P2404 Dodge Code

What does OBDII code P2404 mean for a Dodge vehicle?

P2404 indicates an issue with the Evaporative Emission System Leak Detection Pump Sense Circuit, specifically its range or performance.

What are the common symptoms of code P2404 in a Dodge?

Symptoms may include the check engine light turning on, decreased fuel efficiency, and potential difficulty passing an emissions test.

What causes the P2404 code to appear?

Common causes include a faulty leak detection pump, damaged wiring or connectors in the sense circuit, or a malfunctioning PCM.

Can I drive my Dodge with the P2404 code?

While the vehicle may still be drivable, prolonged use without addressing the issue can lead to increased emissions and potential damage to the evaporative system.

How is the P2404 code diagnosed?

Technicians typically use a scan tool to confirm the code, visually inspect the wiring and connectors, and test the functionality of the leak detection pump.

What repairs can resolve the P2404 code?

Repairs may include replacing the leak detection pump, repairing or replacing damaged wiring or connectors, or updating/reprogramming the PCM.

Is the P2404 code related to fuel system leaks?

Not directly. The code refers to the performance of the leak detection pump's sense circuit, which monitors for leaks in the evaporative emission system.
