P2019
Intake Manifold Runner Position Sensor/Switch Circuit Bank 2
Fuel & air metering
Generic OBD-II
Low
What it means
P2019 means the PCM sees a circuit problem with the bank 2 intake manifold runner position sensor — the sensor that reports where the intake runner flaps actually are. It's typically a sensor, wiring, or connector fault, and it mainly affects low-speed performance and emissions rather than the engine's ability to start and run.
Low
Can I keep driving? Safe to drive; you may notice slightly reduced low-end response, but the engine runs normally otherwise.
Common symptoms
What you'll notice
- Check-engine light on
- Slightly reduced low-speed power
- Occasional hesitation
- Minor drop in fuel economy
Common causes
Most likely first
- Faulty intake manifold runner position sensor/switch on bank 2Likely
- Open or shorted wiring in the sensor circuitCommon
- Corroded or loose connector at the sensorCommon
- Sticking runner control linkage giving an implausible positionLess often
- Damaged powertrain control module (PCM)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data, then inspect the bank 2 runner position sensor wiring and connector for damage or corrosion.
- Compare the sensor's live reading to the commanded runner position for a plausibility mismatch.
- Check that the runner control moves freely and isn't stuck, which can skew the sensor reading.
- Replace the position sensor if it tests faulty; consider the PCM only after wiring and sensor check out.
FAQ
Quick answers
Is it safe to drive with P2019?+
Yes. This is a position-sensor circuit fault, not a running-gear failure, so the main effects are the warning light and slightly softer low-end response. Repair it to keep performance and emissions correct.
Can I just clear P2019?+
It will return until the sensor or wiring fault is repaired — clearing does not fix the circuit.
