P2023
Intake Manifold Runner Position Sensor/Switch Circuit Intermittent Bank 2
Fuel & air metering
Generic OBD-II
Low
What it means
P2023 means the PCM saw an intermittent or erratic signal from the intake manifold runner position sensor on bank 2, which reports where the intake runner flaps sit. Because the fault comes and goes, drivability is usually normal. It most often traces to a loose connector or chafed wiring rather than a failed sensor.

Can I keep driving? Fine to drive — this is an intermittent feedback-signal fault; drivability is usually normal aside from an occasional light.
Common symptoms
What you'll notice
- Check-engine light on (may come and go)
- Occasional brief hesitation or minor torque change
- Often no noticeable driving symptom at all
Common causes
Most likely first
- Loose, corroded, or intermittent connector at the runner position sensor on bank 2Likely
- Chafed or intermittently shorting wiring in the sensor circuitCommon
- Faulty intake manifold runner position sensor/switchCommon
- Sticking runner linkage giving erratic position feedbackLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and check for related runner codes (P2020–P2022).
- Wiggle-test the sensor connector and harness while watching the position signal for dropouts.
- Clean or reseat the connector; repair any chafed wiring found.
- If the signal stays erratic with good wiring, replace the position sensor. Clear and re-test.
FAQ
Quick answers
Is it safe to drive with P2023?+
Yes. It's an intermittent position-sensor signal, so drivability is usually normal. Have it looked at so it doesn't develop into a steady fault.
Can I just clear P2023?+
Being intermittent, it may stay away for a while but returns until the loose connection or sensor is fixed.
