DTC P2413:Exhaust Gas Recirculation (EGR) System Malfunction

General Description

The exhaust gas recirculation (EGR) valve, which is controlled by the powertrain control module (PCM), is opened and the exhaust gas flows through the EGR valve, the intake manifold, and the EGR passage. The exhaust gas is circulated into the air/fuel mixture and the mixture is drawn into the combustion chamber to lower combustion temperatures, thus reducing oxides of nitrogen (NOx) emissions. A sensor (lift sensor) is built into the EGR valve and detects the amount of valve lift. The command value for the target valve lift is stored in the PCM so that exhaust gas recirculation can be optimized according to driving conditions. Comparing this command value with the lift sensor output signal value, the PCM controls the EGR valve to make the amount of actual valve lift equal to the command value. If the valve sensor output is insufficient for the commanded valve lift, the PCM detects a malfunction and stores a DTC.

[ ]: HDS Parameter

Malfunction Threshold
If the actual valve lift is 0.005 in (0.15 mm) or less for at least 5.0 seconds, the valve is considered stuck closed.

Possible Cause
NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
EGR valve closed stuck
EGR valve position sensor line open
EGR valve position sensor line short
EGR valve position sensor middle stuck
EGR valve position sensor range/performance problem

Confirmation Procedure
Operating Condition
1.
Start the engine. Hold the engine speed [ENGINE SPEED] at 3,000 rpm without load (A/T in P or N, M/T in neutral) until the radiator fan comes on, then let it idle.
2.
Drive the vehicle at a speed between 15 - 75 mph (24 - 120 km/h) for at least 5 seconds.
Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.
With the HDS
Select the EGR TEST in the INSPECTION MENU with the HDS.

Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the PCM memory. If the malfunction returns in the next (second) drive cycle, the MIL comes on and a Confirmed DTC and the freeze data are stored.

Conditions for clearing the DTC
The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the battery.
