This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with a part of the engine that helps control air flow. It's like a door that opens and closes to let air in, and the computer is having trouble knowing if the door is in the right position.
The P2023 code is triggered when the Engine Control Module (ECM) detects an intermittent issue with the intake manifold runner position sensor or switch circuit on bank 2. This sensor helps manage the air entering the engine for optimal performance.
The intake manifold runner control system is responsible for optimizing the air intake into the engine's cylinders. Bank 2 refers to the side of the engine opposite to cylinder 1. The position sensor/switch monitors the position of the intake manifold runner flaps. An intermittent circuit issue suggests that the signal from the sensor is not consistent, which can affect engine performance.
• Check Engine Light is on
• Poor engine performance
• Reduced fuel efficiency
• Faulty intake manifold runner position sensor
• Wiring issues such as frayed wires or poor connections
• Malfunctioning intake manifold runner control valve
Intake Manifold: Part of the engine that distributes air to the cylinders.
Runner: A passage in the intake manifold that directs air flow.
Bank 2: The side of the engine opposite to cylinder 1.
• Scan the vehicle for codes and note any related codes.
• Inspect the wiring and connectors for damage or corrosion.
• Test the intake manifold runner position sensor for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the intake manifold runner position sensor if faulty.
• Replace the intake manifold runner control valve if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regular maintenance checks
• Ensure clean air filters
• Inspect wiring and connectors periodically
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if unsure.
• Regularly maintain the engine to prevent future issues.
Check with the vehicle manufacturer for specific warranty coverage on emissions-related components.
This code has been more common in vehicles with higher mileage and those that have not had regular maintenance.
Moderate – It's important to address this issue to maintain engine performance and efficiency.
Driving with this issue may not be illegal, but it can lead to poor performance and increased emissions.
• Engine at operating temperature
• Vehicle in a safe and stable condition
The intake manifold runner position sensor is typically located on the intake manifold, which is on the top of the engine.
Q: Can I drive with a P2023 code?
A: You can drive short distances, but it's best to fix the issue soon to avoid engine performance problems.
Q: What happens if I ignore this code?
A: Ignoring the code can lead to decreased engine performance and fuel efficiency, and may cause further damage over time.

Fitment Required · Vehicle-fitment part
Relevant for airflow, fuel-trim, and intake-metering faults after confirming the sensor is actually at fault.
Airflow and fuel-trim codes can involve the mass air flow sensor after proper diagnosis.
Verify the sensor design and fitment for your exact vehicle.
