Default P2413 errror code 3.2 DID

Hi
I have been getting this error code almost every time I drive the car for a couple of weeks now. Sometimes the engine light comes on just by turning the ignition on.
P2413 - Exhaust Gas Recirculation System Performance
I've had the resistor mod and blocking plate in the EGR for a couple of years now without a problem.
I've checked the resistor...no breakage there....I will check it again with a multi-meter next chance I get.
Could the problem be the EGR valve is sticking???
Any help will be greatly appreciated.
Cheers

If the diagnosis code is stored, the exhaust gas recirculation valve (DC motor) could possibly not be checked correctly.

1. CHECKING THE OPERATION SOUND
Start up the engine and run on at idle speed toallow the engine coolant temperature to reach at least 70°C.
When turning the ignition switch to the LOCK (OFF) position and stopping the engine, check that the operating sound "clicking noise" is heard from the exhaust gas recirculation valve three times.
If the operating sound is not heard, check the drive circuit of the DC motor.
NOTE: If the circuit is normal and the operating sound is not heard, it could possibly be caused by
the failed exhaust gas recirculation valve.

2. OPERATION CHECK
Remove the exhaust gas recirculation valve (attached image).
You need independent 5V power supply source for this test (see in attached image) + voltmeter.
Connect the terminal (+) of the sensor power supply (5 V) with the terminal No. 3 of the exhaust
gas recirculation valve connector, and connect the terminal (−) of the sensor power supply (5 V) with the terminal No. 2.
Voltmeter is to be connected between the terminal No.1 and No. 2.
Connect the terminal (+) of the power supply with the terminal No. 6 of the exhaust gas recirculation valve connector, and connect the terminal (−) of the power supply with the terminal No. 4. Confirm the exhaust gas recirculation valve is opened.(see in second attached pict).

NOTE: At this time, the power supply voltage is to be 5 V. When the valve is not opened, increase
the voltage 1 V by 1 V. For each voltage, current is to be applied within 5 seconds. Once the valve is opened, the voltage is not to be increased any more.

If the exhaust gas recirculation valve is not opened although the voltage applied to the motor
is increased to 9V, clean the exhaust gas recirculation valve and carry out the operation check
again. Despite this, replace the exhaust gas recirculation valve if it does not operate.

Confirm the voltage is changed between the terminal No. 1 and No. 2 together with the exhaust
gas recirculation valve opening movement. By the voltage changed, the DC is recognized as being normal. Use a new gasket and tighten the installation bolt to the tightening torque. Tightening torque: 48 ± 6 Nm

CLEANING THE EGR VALVE
Do not use a solvent or detergent, which could enter the motor and cause it to malfunction.
Remove the exhaust gas recirculation valve and check that the exhaust gas recirculation valve is not stuck or clogged with carbon deposits. Use a wire brush to clean the valve if necessary.

and one more hint
If you have OBD II interface, there is also easy check of EGR operation.
Prerequisites:
OBD II interface + Smart APP Torque Pro (no Torque light)
There is a feature - Logging = you can log all supported PIDs (sensors).
Most important for the EGR check is this one:
EGR Error(%)
+ supported value for EGR Commanded (%)

EGR ERROR = EGR_ERR: This parameter is displayed in percentage and represents EGR position errors. The EGR Error is also normalized for all types of EGR systems. The reading is based on a simple formula: (Actual EGR Position − Commanded EGR) ÷ Commanded EGR = EGR Error.

For example, if the EGR valve is commanded open 10% and the EGR valve moves only 5% (5% − 10%) ÷ 10% = −50% error.

If the scan tool displays EGR Error at 99.2% and the EGR is commanded OFF, this indicates that the PCM is receiving information that the EGR valve position is greater than 0%. This may be due to an EGR valve that is stuck partially open or a malfunctioning EGR position sensor.

check it.

Btw:
COMMAND EGR = EGR_PCT: Commanded EGR is displayed as a percentage and is normalized for all EGR systems. EGR commanded OFF or Closed will display 0%, and EGR commanded to the fully open position will display 100%. Keep in mind this parameter does not reflect the quantity of EGR flow—only what the PCM is commanding. But most important for callculation of the EGR Error.
