Intake Manifold Runner Position Sensor Range/Performance Problem (Bank 1)

There's a sensor that tracks how much air is flowing through the intake manifold. If it's not reading the position correctly, the engine can struggle to breathe properly, affecting performance.

The engine control module (ECM) expects a voltage signal from the intake manifold runner position sensor that corresponds to the position of the runners. If this value is outside of the expected range (typically 0.5 to 4.5 volts), the code sets.

Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.

1. 1Check the wiring and connectors at the intake manifold runner position sensor for any damage or corrosion. Repair as needed.
2. 2Using a multimeter, test the voltage signal coming from the sensor with the engine running. Look for a reading between 0.5V and 4.5V.
3. 3If the voltage is out of range, replace the intake manifold runner position sensor and retest. If it’s within range, inspect the intake manifold for proper operation and look for any obstructions.

• Faulty intake manifold runner position sensor
• Wiring issues or poor connections
• Intake manifold issues such as carbon buildup
• Mechanical failure in the intake manifold assembly
