P0404 Dodge Code - Exhaust Gas Recirculation Position Sensor Performance
Quick Answer
The P0404 diagnostic trouble code for Dodge vehicles specifically relates to an issue with the Exhaust Gas Recirculation (EGR) system's position sensor performance. Common causes include Faulty EGR position sensor, Wiring issues or electrical faults, EGR valve blockages. 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 P0404 Dodge Description
The P0404 diagnostic trouble code for Dodge vehicles specifically relates to an issue with the Exhaust Gas Recirculation (EGR) system's position sensor performance. The EGR system is a crucial component in reducing harmful emissions by recirculating a portion of exhaust gases back into the engine's intake manifold. This process helps control combustion temperatures and reduces the formation of nitrogen oxides (NOx).
Common Causes of P0404 Dodge
- Faulty EGR position sensor
- Wiring issues or electrical faults
- EGR valve blockages
- Carbon buildup in the EGR system
- Vacuum leaks in the EGR system
Symptoms of P0404 Dodge
- Decreased fuel efficiency
- Rough idling
- Engine knocking or pinging noises
- Hesitation or stalling during acceleration
- Illuminated Check Engine Light (CEL)
How to Fix P0404 Dodge
- Use an OBD-II scanner to retrieve the specific fault code and confirm the issue.
- Inspect the EGR position sensor and associated wiring for any signs of damage or corrosion.
- Test the EGR valve for proper operation and clean or replace it if necessary.
- Check for blockages in the EGR system and clean out any carbon deposits.
- Clear the fault code and perform a test drive to ensure the issue has been resolved.
Cost to Fix P0404 Dodge
The typical repair costs for addressing a P0404 code on a Dodge vehicle can range from $150 to $400, including parts and labor. However, it's important to note that actual costs may vary depending on the specific diagnosis time, labor rates, and parts needed for the repair. Auto repair shops commonly charge between $80 and $150 per hour for labor, with rates potentially higher in metropolitan areas or at dealerships, and lower at independent shops. For a more accurate estimate, it's advisable to consult local repair shops and obtain multiple quotes before proceeding with the repair.

Frequently Asked Questions about P0404 Dodge Code
1. What does the OBDII code P0404 mean for a Dodge vehicle?
P0404 indicates a performance issue with the Exhaust Gas Recirculation (EGR) position sensor, meaning the sensor is reporting values outside the expected range.
2. What are the common symptoms of code P0404 in a Dodge?
Symptoms may include the Check Engine Light turning on, poor engine performance, rough idling, reduced fuel efficiency, or increased emissions.
3. What causes the P0404 code to appear in a Dodge?
Common causes include a faulty EGR valve, carbon buildup in the EGR system, a malfunctioning EGR position sensor, or wiring and connector issues.
4. Can I drive my Dodge with a P0404 code?
While the vehicle may still be drivable, driving with a P0404 code for an extended period can lead to increased emissions, reduced performance, and potential damage to the engine or catalytic converter.
5. How do I diagnose the P0404 code on my Dodge?
Diagnosis involves checking the EGR valve for proper operation, inspecting for carbon buildup, testing the EGR position sensor, and examining wiring and connectors for damage or corrosion.
6. What repairs can fix the P0404 code in a Dodge?
Possible repairs include cleaning or replacing the EGR valve, replacing the EGR position sensor, repairing damaged wiring, or removing carbon buildup in the EGR passages.
7. How much does it cost to repair a P0404 code in a Dodge?
Costs can vary, but replacing the EGR valve typically ranges from $150 to $400, depending on parts and labor, while cleaning the system or repairing wiring may cost less.
8. Can a P0404 code cause engine damage in a Dodge?
If left unresolved, it can lead to engine inefficiency, overheating, or potential damage to the catalytic converter over time.
9. What tools are needed to troubleshoot the P0404 code?
You’ll need an OBDII scanner, a multimeter to test wiring, and possibly tools to remove and inspect the EGR valve and passages.
10. How can I prevent the P0404 code from recurring in my Dodge?
Regular maintenance, such as cleaning the EGR system and using quality fuel to reduce carbon deposits, can help prevent the P0404 code from appearing again.

A loose or worn gas cap can definitely set some EVAP system codes, but it won’t trigger a P0404. That one is strictly related to the EGR valve and the EGR position sensor, not the fuel tank or EVAP system.
P0404 means the EGR valve isn’t moving the way the computer expects — either sticking, carboned up, or giving an incorrect position signal. Common causes are a sticking EGR pintle, carbon buildup in the passages, or a failing EGR position sensor.
So while a gas cap issue is real for codes like P0440, P0455, P0456, etc., it doesn’t apply to P0404.
If someone has a P0404, the focus should be on cleaning or replacing the EGR valve, not the gas cap.
