Dodge Journey P0402: EGR → Excessive Flow Diagnosis
The EGR system on a vehicle is responsible for recirculating exhaust gasses, which help keep the engine’s compression temperature below 2500 degrees Fahrenheit. P0402 is an OBDII trouble code that will appear in the Dodge Journey.
Dodge Journey P0402 Symptoms
When P0402 is triggered, you will usually notice no symptoms other than the service engine light blinking, but in more extreme cases, you may notice low engine power, hesitation, or the engine dying at idle.
P0402 Causes: Dodge Journey
The P0402 code in the Journey can be caused by a variety of factors, and determining what is causing the issue is usually not difficult.
Journey P0402 Fix
Checking the EGR valve and the DPFE sensor are two common fixes.
The DPFE sensor is the most difficult part, but if you can handle it, you can probably do a home test run.
How do you fix exhaust gas recirculation flow excessive detected?
What fixes are available for the P0402 error code?
- Replacing a stuck open EGR valve. Replacing a broken catalyst in the exhaust. Replacing an EGR temperature sensor or cleaning the carbon off of it to repair it if it registers too much of a temperature change.
Where is the EGR valve located on a 2010 Dodge Journey?
Look at the front of the intake manifold for the EGR valve, which will be bolted to the intake manifold directly in front of the carburetor.
How do you fix an exhaust gas recirculation control circuit?
What fixes are available for the P0403 error code?
- Replacing a corroded connector to the EGR vacuum control solenoid.
- Repairing the wiring shorted to the EGR vacuum control solenoid.
What causes excessive EGR flow?
Another common cause of excessive EGR flow is a damaged EGR valve gasket that creates an airtight seal between the EGR valve and its mounting surface. A damaged EGR valve gasket can allow exhaust to leak into your engine even when the EGR valve is closed.
Can I drive with a P0402 code?
It is yours to drive for as long as you want.
How do I fix code P0401?
What can be done to fix the P0401 error code?
- Replacing a broken vacuum line to the EGR valve or control solenoid. Replacing an EGR temperature sensor or cleaning the carbon off of it to repair it if it does not register enough of a temperature change.
How can you tell if the EGR valve is bad?
What are the signs and symptoms of a malfunctioning EGR valve?
- Your engine has a rough idle.
- Your car has poor performance.
- You have increased fuel consumption.
- Your car frequently stalls when idling.
- You can smell fuel.
- Your engine management light stays on.
- Your car emits more emissions.
How much is an EGR valve for a 2010 Dodge Journey?

What is the exhaust gas recirculation control circuit?
The exhaust gas recirculation (EGR) system helps to reduce nitrogen oxide gases in your vehicle’s exhaust by detecting an open circuit condition of an EGR motor control circuit for more than 3 seconds with the ECM/PCM.
Where is the EGR solenoid located?
The EGR solenoid is normally attached to the engine block with a nut and is located close to the EGR valve. It can be found by following the rubber vacuum hose from the EGR valve on the back of the engine block to the solenoid. Replacing the EGR solenoid takes only a few minutes and you can save time by doing it yourself.
What causes code P0405?
When the EGR position falls below the ECM expected sensor position, code P0405 is triggered, and the most common cause is an open circuit in the EGR sensor.
Can I drive with a bad EGR valve?
Can I drive with a bad EGR valve? Technically, you can drive with a bad EGR valve, but your vehicle will run rough, shake at idle, and you may hear popping sounds while driving down the road.
How do you fix a EGR flow malfunction?
What can be done to fix the P0400 error code?
- Cleaning carbon out of EGR tubes to intake manifold.
- Replacing a broken vacuum line to the EGR valve.
- Replacing an EGR temperature sensor or cleaning the carbon off of it to repair it.
Can EGR cause rich condition?
EGR Valves allow burned exhaust gases to reenter the intake manifold, reducing the amount of oxygen available and causing a rich fuel condition.
