P2023 — Intake Manifold Runner Position Sensor/Switch Circuit Intermittent Bank 2

OBD2 code P2023 flags a problem with the sensor and actuator circuits (intake manifold runner position sensor/switch circuit intermittent bank 2). The car is usually drivable while you plan the repair. Common culprits: faulty sensor or actuator of the affected circuit, poor ground connection, blown fuse feeding the circuit.

powertrain (engine/transmission)

Is it safe to drive?

Short-term driving is OK In most cases the car remains drivable, possibly with reduced performance or a disabled auxiliary system. If symptoms include stalling, no-start or brake/steering warnings, treat it as urgent.

How to diagnose with an OBD scanner

  1. Read the code and freeze frame Connect an OBD2 scanner, confirm P2023 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
  2. Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
  3. Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the intake manifold runner position sensor/switch circuit intermittent bank 2 for damage, corrosion, chafing or poor contact.
  4. Subsystem check Measure reference voltage, ground and signal continuity at the component connector.
  5. Subsystem check Wiggle-test the harness while watching the signal in live data — dropouts reveal broken wires.
  6. Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2023 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P2023 (parts and labor, USD, independent shop rates): Replace the faulty sensor or actuator: $150–$500; Control module repair: $300–$1,000; Repair wiring or connectors: $80–$250. Overall, fixing P2023 usually costs between $80 and $1,000. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

Common questions

What are the symptoms of P2023?

Drivers most often notice: the affected system operates intermittently or not at all, Check Engine Light on, increased fuel consumption in some cases, possible limp mode depending on the affected component.

What is the most common cause of P2023?

The most common causes are: faulty sensor or actuator of the affected circuit, poor ground connection, blown fuse feeding the circuit.

What does OBD2 code P2023 mean?

In most cases the car remains drivable, possibly with reduced performance or a disabled auxiliary system. If symptoms include stalling, no-start or brake/steering warnings, treat it as urgent.

How much does it cost to fix P2023?

Replace the faulty sensor or actuator — $150–$500; Control module repair — $300–$1,000; Repair wiring or connectors — $80–$250. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

What does P2023 mean?

The engine control module sets P2023 when it detects a fault in the sensor and actuator circuits. In practical terms: intake manifold runner position sensor/switch circuit intermittent bank 2. The code belongs to the powertrain (engine/transmission) group of OBD2 codes.

“Bank 2” means the side of the engine opposite to cylinder 1. Verify which side that is on your specific engine before testing or replacing parts.

The module monitors this system continuously while driving. When readings fall outside the expected range for a defined number of drive cycles, it stores P2023 and switches on the warning light. Freeze frame data saved with the code shows the exact conditions — rpm, load, temperature, speed — at the moment the fault was detected, which is the best starting point for diagnosis.

Common symptoms of P2023

  • the affected system operates intermittently or not at all
  • Check Engine Light on
  • increased fuel consumption in some cases
  • possible limp mode depending on the affected component

What causes P2023?

  • blown fuse feeding the circuit
  • corroded, loose or damaged connector
  • control module driver fault
  • open or shorted wiring in the circuit
  • faulty sensor or actuator of the affected circuit
  • poor ground connection
