What Does P2019 Mean?
DTC P2019 indicates a general circuit malfunction in the intake manifold runner position sensor or switch on bank 2. This is the bank 2 equivalent of P2014. The ECM has detected that the bank 2 IMRC position sensor signal is outside its normal operating range, erratic, or absent, preventing verification of bank 2 runner flap position.
Common Causes
35%
Faulty IMRC position sensor/switch on bank 2
25%
Damaged or corroded wiring to the bank 2 IMRC position sensor
20%
Poor connector contact at the bank 2 position sensor
12%
Missing or incorrect 5V reference voltage at the bank 2 sensor
8%
Mechanical failure in the IMRC linkage preventing sensor reading
Diagnostic Steps
1
Verify 5V reference voltage is present at the bank 2 IMRC position sensor connector.
2
Check the sensor ground (signal return) circuit for proper continuity to the ECM.
3
Monitor the bank 2 IMRC position sensor PID while manually operating the runner flaps; look for smooth, linear signal change.
4
Inspect the bank 2 sensor connector for bent pins, moisture, or contamination.
5
Compare bank 2 sensor readings with bank 1 under identical conditions to isolate the fault.

The most common cause of P2019 (Intake Manifold Runner Position Sensor/Switch Circuit Bank 2) is: Faulty IMRC position sensor/switch on bank 2
Typical repair costs for P2019 range from $80 to $350, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Low safety risk. Bank 2 IMRC position feedback is compromised but the engine continues to run. Slight reduction in performance optimization.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2019 to identify the root cause.
