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 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.
