P2010 - INTAKE MANIFOLD RUNNER CONTROL (IMRC) SOLENOID CONTROL CIRCUIT HIGH VOLTAGE
The intake manifold runner is a long moveable divider inside the intake manifold, which changes induction airflow characteristics as it pivots above a certain engine speed/load range. The ECM controls the intake manifold runner by controlling the intake manifold runner control (IMRC) solenoid. The IMRC solenoid is supplied continuous ported vacuum, which is transferred to the intake manifold runner diaphragms whenever the solenoid is energized. The ECM controls the solenoid by supplying the circuit ground. When the solenoid is commanded Off (circuit not grounded). the voltage level at the ECM should be high (ignition voltage). When the solenoid is commanded On (circuit grounded), the voltage level at the ECM should be low. The ECM IMRC solenoid feedback circuit uses a pull-up voltage (4.6-6.6 volts), which allows the ECM to individually differentiate between an open, short to ground or short to voltage. DTC P2010 will set if the ECM detects higher than normal feedback voltage when the IMRC solenoid is commanded On with the engine running.

DTC PARAMETERS
DTC P2010 will set if IMRC solenoid feedback voltage is greater than 6.6 volts when IMRC solenoid is commanded On when:
^ Condition exists for longer than 0.5 seconds
^ Engine speed is greater than 40 rpm
^ Battery voltage is between 7.5 and 15 volts

DTC P2010 diagnostic runs continuously once the above conditions have been met.

P2010 is a type D DTC

DIAGNOSTIC AIDS
To locate an intermittent problem. use Scan tool to command INTAKE MANIFOLD RUNNER CONTROL solenoid On and Off with ignition On, engine Off. Wiggling wires while listening for the solenoid to stop clicking when commanded On and Off may locate a shorted solenoid or the area where a short to voltage in the wiring may exist.

IMRC solenoid resistance: 18-27 ohms
