What Does P2023 Mean?
DTC P2023 indicates the intake manifold runner position sensor signal on bank 2 is exhibiting intermittent behavior. This is the bank 2 counterpart to P2018. The ECM has detected momentary signal dropouts, spikes, or erratic fluctuations from the bank 2 IMRC position sensor that do not correspond to actual runner movement, indicating a developing wiring, connector, or sensor fault.
Common Causes
35%
Loose or worn connector at the bank 2 IMRC position sensor
25%
Intermittent wire break in the bank 2 sensor circuit due to vibration
20%
Corroded connector pins creating intermittent contact on bank 2
15%
Failing bank 2 IMRC position sensor with internal intermittent fault
5%
Loose ECM connector pin on the bank 2 sensor input
Diagnostic Steps
1
Monitor the bank 2 IMRC position sensor PID on a live graph and watch for sudden signal spikes or drops.
2
Wiggle the bank 2 IMRC position sensor connector and nearby harness sections while watching the PID for induced signal interruptions.
3
Inspect connector pins for corrosion, terminal spread, or signs of intermittent contact.
4
Flex the wiring harness along its routing to the sensor, checking for breaks that manifest under movement.
5
If the fault is difficult to reproduce, consider proactive connector and terminal repair or sensor replacement to prevent progression.

The most common cause of P2023 (Intake Manifold Runner Position Sensor/Switch Circuit Intermittent Bank 2) is: Loose or worn connector at the bank 2 IMRC position sensor
Typical repair costs for P2023 range from $60 to $350, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Minimal safety concern. Intermittent sensor faults may cause brief IMRC control anomalies but do not affect safe vehicle operation. Repair at your convenience.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2023 to identify the root cause.
