P2009 - INTAKE MANIFOLD RUNNER CONTROL CIRCUIT LOW BANK 1
Description of DTC code P2009
DTC P2009 OBDII indicates that the Intake Manifold Control (IMRC) solenoid or actuator has a low voltage condition.
The purpose of the intake manifold runner is to increase or decrease the speed at which the intake air flows through the inlet manifold. These adjustments are accomplished through an actuator. It is considered the engine speed, throttle position, throttle plate movement speed, and environmental factors.
Symptoms of fault code P2009
- The Motor Malfunction Indicator Light (MIL) turns on.
- No motor start condition.
- At low engine speeds, there is a lack of power.
- Erratic idling.
- Problems during acceleration.
Causes of OBD2 P2009
Reasons to store the P2009 OBD2 diagnostic code:
- Intake Manifold Control (IMRC) solenoid actuator circuit wires or connectors may be faulty.
- The IMRC solenoid may be broken.
- Perhaps, the Intake Manifold Control Sensor (IMRC) is damaged.
- The Manifold Absolute Pressure Sensor (MAP) may be in bad condition.
Possible solutions of the DTC code P2009
To solve the faults associated with the P2009 OBDII fault code, try this:
- Check the Intake Manifold Control system wires, connectors, and vacuum lines, and check them for damage. Repair and replace any components as required.
- Make reference voltage, continuity, resistance, and ground tests on all system cables. The results obtained should be compared with the values indicated by the manufacturer. Fix if necessary.
- Consult the information source for recommended test specifications for both the IMRC actuator solenoid and the IMRC Runner Position Sensor. Replace any component that does not meet the specification.
