P2010 - INTAKE MANIFOLD RUNNER CONTROL CIRCUIT HIGH BANK 1
Description of DTC code P2010
The Powertrain Control Module (PCM) electronically monitors and makes adjustments to the Intake Manifold Control system. This system manages the air entering the intake manifold, combustion chambers, and cylinder heads. It has metal flaps, which are individually attached to the intake manifold ports of each cylinder. The flaps are opened by an electronic stroke control actuator.
When the P2010 OBDII diagnostic code is stored, it means that the PCM has found a higher-than-expected voltage in the Intake Manifold Control Actuator / Sensor (IMRC) circuit. That code is set for one side of the engine where the number 1 cylinder is located, i.e., bank 1.
Symptoms of fault code P2010
- Check Engine light ON.
- The vehicle has problems during the acceleration.
- At low engine speeds, the engine loses power.
- The fuel efficiency is reduced.
Causes of OBD2 P2010
Reasons for setting the P2010 OBD2 fault code:
- Manifold runners may not be properly adjusted.
- Maybe the Intake Manifold Control Actuator solenoid has a failure.
- The IMRC actuator may be damaged.
- The IMRC actuator solenoid control circuit wiring may be open or shorted.
- There could be excessive carbon buildup on the flaps of the Intake Manifold Control system.
- The Manifold Absolute Pressure (MAP) sensor might be faulty.
Possible solutions of the DTC code P2010
To troubleshoot the problems related to the P2010 OBDII DTC, follow these suggestions:
- Consult the Technical Service Bulletins (TSB).
- Visually, check that the Intake Manifold Control system wires are in good condition. Check for worn wires or burn spots. Also, check the IMRC Sensor connector for corrosion or any misadjustment. Fix if necessary, and then clear the code.
- Use the manufacturer's specifications for the resistance of the IMRC actuator and solenoid. Use a DVOM to verify that these voltages are within the recommendations. Also, test the continuity of all the circuits in the system. Replace any of these components that do not comply. Before performing these tests, disconnect the controllers.
