What Does P2020 Mean?
DTC P2020 indicates the intake manifold runner position sensor on bank 2 is reporting values outside the expected range or is not tracking properly with the commanded runner position. This is the bank 2 counterpart to P2015. The sensor is electrically functional but its readings do not match expected IMRC positions during actuation, suggesting a mechanical or calibration issue.
Common Causes
30%
Carbon deposits restricting full runner travel on bank 2, causing range mismatch
25%
Worn or misadjusted IMRC position sensor on bank 2
20%
Mechanical play in the bank 2 runner linkage between actuator and sensor
15%
Intermittent connector issue at the bank 2 IMRC position sensor
10%
Partially failed IMRC actuator on bank 2 not achieving full stroke
Diagnostic Steps
1
Monitor the bank 2 IMRC position sensor PID and compare actual versus commanded position during scan tool bidirectional actuation.
2
Inspect bank 2 intake runner flaps for carbon buildup or physical obstruction preventing full range of motion.
3
Manually move the bank 2 runners through their full travel while watching the sensor PID for smooth, linear output.
4
Check the linkage between the bank 2 IMRC actuator and position sensor for wear, looseness, or misalignment.
5
Compare bank 2 sensor range with bank 1 to identify whether the sensor or the mechanism is at fault.

The most common cause of P2020 (Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance Bank 2) is: Carbon deposits restricting full runner travel on bank 2, causing range mismatch
Typical repair costs for P2020 range from $100 to $400, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Minimal safety risk. The engine may not fully optimize intake runner position on bank 2, causing slight power and efficiency reduction. Vehicle is safe to operate.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2020 to identify the root cause.
