The P2023 fault code refers to an issue with the Intake Manifold Runner Position Sensor/Switch Circuit for Bank 2. This code indicates that the sensor or its circuit is experiencing intermittent failures, which can affect engine performance and efficiency. The intake manifold runner control system adjusts the intake manifold runner length in order to improve engine efficiency across a range of speeds and loads.

What are the symptoms of the P2023 code?

• Check engine light illuminated
• Reduced engine performance or power
• Poor fuel economy
• Rough idling or stalling
• Difficulty in acceleration or throttle response

What causes the P2023 code?

• Faulty intake manifold runner position sensor
• Poor electrical connection or damaged wiring in the circuit
• Issues with the engine control module (ECM)
• Intake manifold leaks or blockage affecting sensor readings

How to fix P2023?

• Inspect and repair any damaged wiring or poor connections in the circuit
• Replace the faulty intake manifold runner position sensor
• Ensure there are no intake leaks or blockage affecting the sensor operation
• Clear the fault code and test drive the vehicle to ensure the issue is resolved
