What Does P2010 Mean?
DTC P2010 indicates the intake manifold runner control (IMRC) circuit on bank 1 is reading higher than expected voltage. The ECM has detected that the control signal to the IMRC actuator is above the maximum calibrated threshold, suggesting an open ground, high-resistance connection, or a short to battery voltage in the circuit.
Common Causes
30%
Open ground circuit for the IMRC actuator on bank 1
25%
Short to battery voltage in the IMRC control wire
20%
High-resistance connection at the IMRC actuator connector
15%
Failed IMRC solenoid with open internal coil (high impedance)
10%
ECM output driver fault holding the circuit high
Diagnostic Steps
1
Review freeze frame data for engine operating conditions when the code was set.
2
Inspect the bank 1 IMRC actuator connector for spread pins, corrosion, or looseness that could create high resistance.
3
Measure voltage at the IMRC actuator connector with the key on; compare control side and ground side against specifications.
4
Check the ground circuit from the IMRC actuator back to the ECM for continuity and resistance (should be near 0 ohms).
5
Verify no wiring is chafed against positive voltage sources that could short the control wire high.
6
If all wiring checks pass, test the IMRC solenoid resistance and replace if out of specification.

The most common cause of P2010 (Intake Manifold Runner Control Circuit High Bank 1) is: Open ground circuit for the IMRC actuator on bank 1
Typical repair costs for P2010 range from $75 to $450, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Low safety risk. The IMRC may default to a single runner length, causing reduced performance at certain RPM ranges. Vehicle can be safely driven.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2010 to identify the root cause.
