Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance Problem (Bank 1)
There's a problem with the intake manifold runner position sensor on bank 1.
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 intake manifold runner controls airflow into the engine; if it’s stuck or not reading correctly, the engine can lose power or efficiency.
What the computer is actually seeing
The engine control module (ECM) expects the intake manifold runner position to be within a certain range. It checks the position sensor reading against expected values to determine if it’s functioning properly.
What a healthy reading looks like
The intake manifold runner position should typically be between 0.5V to 4.5V depending on the engine speed and conditions.
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.
- 1Check for loose or damaged wiring and connectors at the intake manifold runner position sensor. Decision: Are connections secure and intact? (Yes: go to step 2, No: repair wiring/connectors and clear code.)
- 2Using a multimeter, check the voltage at the intake manifold runner position sensor connector. Expected voltage is 0.5V to 4.5V. Decision: Is the voltage within range? (Yes: go to step 3, No: replace the sensor.)
- 3Manually test the intake manifold runner operation by applying vacuum and observing movement. Decision: Does the runner move freely? (Yes: clear codes, monitor for reoccurrence, No: clean or replace the intake manifold runner assembly.)
Common causes
- Faulty intake manifold runner position sensor
- Wiring issues or connector corrosion
- Intake manifold runner stuck mechanically

Frequently asked questions
Is it safe to drive with this code?
It's drivable but can lead to decreased engine performance and fuel efficiency; fix soon.
Will this fault come back after clearing codes?
If the underlying issue isn't resolved, the code will likely return.
Why does this code sometimes pair with P2004?
Both codes relate to intake manifold runner issues, likely due to similar faults affecting the system.
