What Does P2022 Mean?
DTC P2022 indicates the intake manifold runner position sensor on bank 2 is reporting a signal voltage above the maximum threshold. This is the bank 2 counterpart to P2017. The ECM has detected that the bank 2 IMRC position sensor signal is abnormally high, typically near or at the reference voltage level, suggesting an open signal return circuit or a sensor-to-reference short.
Common Causes
30%
Open ground (signal return) wire from the bank 2 IMRC position sensor
25%
Short between signal wire and 5V reference in the bank 2 IMRC sensor circuit
25%
Failed bank 2 IMRC position sensor outputting fixed high voltage
15%
High-resistance ground connection at the bank 2 sensor connector
5%
ECM input channel fault pulling signal high
Diagnostic Steps
1
Measure signal voltage at the bank 2 IMRC position sensor connector; a reading near 5V confirms the high-signal condition.
2
Check the ground (signal return) circuit from the sensor connector to the ECM for continuity and low resistance.
3
Inspect the harness for locations where the signal wire and 5V reference wire run together and could be shorted.
4
Disconnect the sensor and measure signal wire voltage; if it drops significantly, the sensor has an internal fault.
5
If wiring and sensor test good, simulate the sensor signal at the ECM input to verify ECM response.
Estimated Repair Cost

The most common cause of P2022 (Intake Manifold Runner Position Sensor/Switch Circuit High Bank 2) is: Open ground (signal return) wire from the bank 2 IMRC position sensor
Typical repair costs for P2022 range from $70 to $350, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Low safety concern. The ECM cannot verify bank 2 runner position, but the vehicle continues to run safely with reduced intake optimization.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2022 to identify the root cause.
