Intake Manifold Runner Position Sensor/Switch Range/Performance Problem
The intake manifold runner position sensor is reporting a position outside of the expected range.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The engine computer checks the position of the intake valves to adjust airflow; if it sees something it doesn't expect, it sets this code.
What the computer is actually seeing
The PCM expects a voltage signal from the intake manifold runner position sensor that corresponds to the physical position of the runner. If it receives a reading that is too high or too low (for example, below 0.1V or above 4.5V), it will trigger the code.
What a healthy reading looks like
Voltage signal should typically range from 0.5V to 4.5V depending on the position; 0.5V signifies closed, and 4.5V signifies fully open.
Guided diagnostic — the DiagCoach way
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.
- 1Inspect wiring and connectors for damage or corrosion. Repair as necessary. Decision Point: Are there any obvious wiring issues? If yes, fix and retest. If no, proceed to the next step.
- 2Check the voltage at the intake manifold runner position sensor connector with the engine running. You should see a voltage between 0.5V and 4.5V. Decision Point: Is the voltage within range? If yes, proceed to the next step. If no, replace the sensor and retest.
- 3With the engine running, manually actuate the intake manifold runner and observe the position sensor reading on a scan tool. It should smoothly transition between 0.5V and 4.5V. Decision Point: Does the sensor respond correctly? If yes, there may be an issue with the actuator or manifold itself, consider swapping or testing those. If no, replace the sensor and retest.
Common causes
- Faulty intake manifold runner position sensor
- Wiring issues or short circuits
- Faulty intake manifold runner actuator
- Vacuum leaks affecting manifold pressure

Frequently asked questions
Is it safe to drive with this code?
It's generally drivable but can impact performance and fuel economy, so address it soon.
Will this code come back if I clear it?
If the underlying issue isn't fixed, yes, it will likely return.
Why does this code pair with P2006?
P2006 relates to the same system but indicates a different range issue in the runner position; they often share symptoms.
