Code P2404 Description
The P2404 code specifically relates to the Evaporative Emission System Leak Detection Pump Sense Circuit Range/Performance. This code indicates that there is an issue with the circuit that monitors the performance of the leak detection pump in the vehicle's evaporative emission system. The evaporative emission system is responsible for capturing and storing fuel vapor that would otherwise be released into the atmosphere. The leak detection pump is a key component in this system, as it helps monitor for any leaks in the system that could result in harmful emissions being released.
Common Causes of P2404
- Faulty leak detection pump
- Wiring or electrical issues in the sense circuit
- Corrosion or damage to connectors
- Vacuum leaks in the evaporative emission system
- Defective purge valve
Symptoms of P2404
- Check Engine Light illuminated
- Decreased fuel efficiency
- Strong fuel odor
- Failed emissions test
- Rough idling or stalling
How to Fix P2404
- Perform a visual inspection of the evaporative emission system components and wiring to check for any obvious signs of damage or wear.
- Test the leak detection pump and sense circuit using a multimeter to determine if they are functioning properly.
- Replace any faulty components such as the leak detection pump, wiring, connectors, or purge valve.
- Clear the diagnostic trouble codes from the vehicle's computer and perform a test drive to ensure the issue has been resolved.
- If the problem persists, consult a professional mechanic for further diagnostics and repairs.
Cost to Fix P2404
The typical repair costs for addressing a P2404 code can vary depending on the specific cause of the issue and the labor rates in your area. On average, you can expect to pay anywhere from $100 to $500 for parts and labor. Keep in mind that rates may vary based on factors such as the location of the repair shop, the make and model of your vehicle, and the extent of the repairs needed. It's recommended to obtain quotes from multiple shops to ensure you are getting a fair price for the necessary repairs.
