Intake Manifold Runner Position Sensor / Switch Circuit Range / Performance Problem (Bank 1)
This code indicates 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 how air enters the engine. If it's stuck or not working right, the engine can't get the air it needs, which affects performance and emissions.
What the computer is actually seeing
The engine control module (ECM) monitors the position of the intake manifold runner using a sensor. It expects to see a specific voltage change as the engine operates. If the sensor signal is outside the expected range, the code sets.
What a healthy reading looks like
Expect the intake manifold runner position sensor to show between 0.5V to 4.5V while in operation.
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.
- 11. Check the intake manifold runner position sensor connector and wiring for damage or loose connections. Repair as needed. Decision point: Are the connections good? Yes: Go to step 2. No: Fix wiring/connectors and retest.
Common causes
- Faulty intake manifold runner position sensor
- Wiring issues or damaged connectors
- Vacuum leak in the intake system
- Motor or actuator failure
- ECM software issue
