DTC P2009 or P2010 - FX3

Ignition voltage is supplied directly to the IMRC solenoid. The engine control module (ECM) controls the solenoid by grounding the control circuit with a solid state device called a driver. The driver is equipped with a feedback circuit that is pulled-up to a voltage. The ECM can determine if the control circuit is open, shorted to ground, or shorted to a voltage by monitoring the feedback voltage.

P2009

The ECM detects a short circuit to ground or an open circuit on the IMRC solenoid control circuit.

P2010

The ECM detects a short circuit to voltage on the IMRC solenoid control circuit.

DTC P2009 and P2010 are Type E DTCs.

DTC P2009 and P2010 are Type E DTCs.

1. Ignition ON, verify that the DTC P2009 or P2010 is not set.

⇒	If a DTC is set, perform the Circuit/System Testing.

2. Observe the intake manifold runner control valve control circuit test status parameters. Each of the intake manifold runner control valve control circuit test status parameters should display OK or Not Run.
3. Operate the vehicle within the conditions for running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that are captured in the Freeze Frame/Failure Records Data List.

1. Ignition OFF, disconnect the harness connector at the Q21 intake manifold runner control solenoid valve.
2. Ignition ON, verify that a test lamp illuminates between the ignition circuit terminal 1 and ground.

⇒	If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance. If the circuit tests normal and the ignition circuit fuse is open, test all the components connected to the ignition circuit and replace as necessary.

3. Ignition OFF, connect a test lamp between the control circuit terminal 2 and the ignition circuit terminal 1.
4. Ignition ON, command the Intake Manifold Tuning Control Valve Open and Closed with a scan tool. The test lamp should turn ON and OFF.

⇒	If the test lamp remains ON all the time, test the control circuit for a short circuit to ground. If the circuit tests normal, replace the ECM.

⇒	If the test lamp remains OFF all the time, test the control circuit for a short circuit to voltage or an open/high resistance. If the circuit tests normal, replace the ECM.

5. Test for 3-4 volts between the control circuit terminal 2 and ground.

⇒	If the voltage is not within the specified range, replace the ECM.

6. If all circuits test normal, test or replace the Q21 intake manifold runner control solenoid valve.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
