Driving Pattern

1. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the

radiator fan comes on.

2. Let the engine idle for at least 22 seconds.

When a malfunction is detected during the first drive cycle, a Temporary DTC is stored in the PCM
memory. If the malfunction recurs during the next (second) drive cycle, the MIL comes on and the DTC and

Conditions for clearing the MIL

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the
diagnostic runs.

The MIL, the DTC, the Temporary DTC, and the freeze frame data can be cleared by using the scan tool
Clear command or by disconnecting the battery.

DTC P2413 (12): ADVANCED DIAGNOSTICS

DTC P2413: EXHAUST GAS RECIRCULATION (EGR) SYSTEM MALFUNCTION

Fig. 300: Malfunction Determination Graph

General Description

The exhaust gas recirculation (EGR) valve, which is controlled by the powertrain control module (PCM), is
opened and the exhaust gas flows from the exhaust manifold through the EGR valve and 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 the 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, a malfunction is detected.

Malfunction Threshold

If the actual valve lift is 0.006 in. (0.15 mm) or less for at least 5 seconds, the valve is considered stuck
closed.

Confirmation Procedure with the HDS

Do the EGR TEST in the INSPECTION MENU with the HDS.

Driving Pattern

1. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the

radiator fan comes on.

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.
