P2023: Intake Manifold Runner Position Sensor / Switch Circuit Intermittent (Bank 2)

Quick answer: The PCM sees Bank 2 runner position feedback dropping out or changing unpredictably.

Drivers also search this fault as intake manifold runner position sensor intermittent bank 2, IMRC position sensor intermittent bank 2, bank 2 runner feedback intermittent.

Meaning

What P2023 usually means

P2023 is the intermittent Bank 2 runner feedback code. The signal is not staying clearly low or high; instead, it glitches enough that the PCM can no longer trust the Bank 2 position story. Common root causes include loose terminals, partly broken wires, heat-sensitive sensor behavior, or mechanical wear that makes the feedback jump during certain transitions. It is valuable because it completes the full Bank 2 feedback branch and creates stronger internal link symmetry with the existing Bank 1 IMRC pages.

Fast triage

Start here before chasing parts

  • Scan first: save freeze-frame and pending codes before clearing anything.
  • Confirm the complaint: compare the stored code with current drivability symptoms.
  • Use context: trims, live data, and related codes usually narrow the fault faster than guesswork.
  • Work simplest to hardest: leaks, connectors, maintenance items, and known patterns before expensive components.
Initial checks

What to check first

  • Use freeze-frame and mode history to see when the fault appears, because intermittent runner codes often need the right load or temperature to show themselves.
  • Wiggle-test the Bank 2 connector and nearby harness while monitoring live runner feedback if safe to do so.
  • Check whether P2021 or P2022 appears in history, because that often reveals how the signal is failing before it becomes intermittent.
Driving risk

Can you keep driving?

P2023 is usually still driveable, but intermittent runner feedback can make the engine feel inconsistent and can keep monitors from completing cleanly.

Moderate urgency: This code often allows short-term driving, but the right fix usually comes faster when you diagnose it early instead of waiting for more codes.
Symptoms

Common symptoms

Likely causes

Common causes behind this code

  • Loose Bank 2 sensor connector or weak terminal tension
  • Harness conductor partly broken inside the insulation
  • Heat-sensitive Bank 2 position sensor failure
  • Linkage wear that makes the feedback jump between positions
  • Intermittent reference or ground loss at the Bank 2 runner assembly

Cause phrases often tied to this code: intermittent runner feedback, loose connector, broken wire strands, sensor dropout, bank 2 linkage play.

Diagnostic order

Suggested workflow

  1. Capture freeze-frame and pending-code history before clearing the fault.
  2. Inspect Bank 2 connector fit, terminal tension, and harness routing.
  3. Monitor runner feedback while commanding movement and gently moving the harness.
  4. Verify reference voltage and ground stay stable during the wiggle test and heat cycle.
  5. After repair, repeat the original drive conditions and confirm the signal trace stays smooth.
Avoid guesswork

Common mistakes

  • Replacing the manifold because the signal is erratic without proving whether the fault is in the harness or connector.
  • Testing only in the bay when the glitch appears during real road-load transitions.
  • Ignoring historical high- or low-signal codes that would narrow the likely cause faster.
Repair path

Practical fix guidance

  • Repair connector tension, wiring integrity, or unstable reference and ground circuits before replacing major components.
  • If the signal still drops out with proven-good wiring, replace the Bank 2 sensor or integrated actuator assembly as testing supports.
  • Verify stable Bank 2 feedback over a full heat cycle and repeat road test.

FAQ

Quick questions about P2023

Is P2023 just the Bank 2 version of P2018?

Yes. The logic is the same, but diagnosis stays centered on the Bank 2 sensor, connector, harness, and linkage.

Can a loose connector cause P2023 by itself?

Absolutely. Weak terminal tension is one of the most common causes of intermittent runner-position faults.

Why should I avoid clearing P2023 too early?

Because freeze-frame and history data often tell you whether the intermittent signal was trending low, high, or simply dropping out.
