P2019 OBD-II Trouble Code: Intake Manifold Runner Pos Sensor/Switch Circuit Bank 2

P2019 trouble code definition

P2019 is a general OBD2 diagnostic trouble code (DTC) that indicates a problem in with the intake manifold runner control circuit.

What the P2019 code means

The P2019 is set when the intake manifold runner position sensor bank 2 has malfunctioned. Intake manifold runners vary the amount of air going into the air intake and help increase low end torque. The intake manifold runner position sensor tells the ECU how far open or closed the intake runners are.

When the ECU detects a problem with the position sensor for bank 2 the P2019 code is set and a Check Engine Light will be seen on the dashboard. With the Check Engine Light a failsafe mode will be enabled by the ECU to protect the vehicle. This will remain in effect until the code is repaired or normal operation is detected.

What causes the P2019 code?

  • Intake manifold runner control solenoid failure
  • Binding of the intake manifold runner flaps
  • Leaking vacuum line
  • Open or short in the wiring harness
  • Loose, poor, or corroded electrical connection
  • Intake runner position sensor bank 2 that is faulty

What are the symptoms of the P2019 code?

  • Check Engine Light displayed on the dashboard
  • Engine may idle roughly
  • Lack of engine power

How does a mechanic diagnose the P2019 code?

Mechanics follow these simple steps when diagnosing the P2019 code:

  • Using a scan tool hooked into the DLC port, check for any codes and the freeze frame data for each stored in the ECU.

  • Note all of the data found

  • Clear all of the codes

  • Perform a road test of the vehicle to duplicate the symptoms.

  • A visual inspection will be performed looking for any obviously damaged or broken components.

  • The scan tool will be used to access the datastream and check the bank 2 intake manifold position readings to the bank 1 readings.

  • Test the intake manifold control solenoid

  • Lastly, if binding of the flaps is suspected, the intake manifold runners may need to be removed and checked for proper movement.

Common mistakes when diagnosing the P2019 code

  • Even the most experienced technicians can make mistakes if they do not complete all diagnostic steps or do them in the wrong order.

  • A common mistake is overlooking basic causes for the P2019 code such as a vacuum line that is leaking before looking at the more expensive and complex intake manifold runner control solenoid.

How serious is the P2019 code?

  • The P2019 code will not prevent the vehicle from being driven to a safe location once the malfunction occurs.

  • In most cases the driver may not even notice the symptoms other than the Check Engine Light. Any code should be repaired as soon as possible to get the vehicle back to normal operation.

What repairs can fix the P2019 code?

  • Intake manifold runner control solenoid replaced
  • Replacement of leaking vacuum lines
  • Wiring harness repaired or replaced
  • Poor electrical connection resolved
  • Unbinding the intake manifold control runner flaps
  • Intake runner position switch bank 2 replaced

Additional comments for consideration regarding the P2019 code

In cases where the intake manifold runner flaps are bound it is usually due to carbon deposits found within the intake. As the vehicle's mileage increases the carbon deposits can build up in various places, the intake runner flaps are one.

Special intake system cleaners can be used in some scenarios to remove the carbon buildup and restore proper operation without needing to replace any components.
