Intake Manifold Runner Position Sensor 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)
Your engine's computer is getting strange signals from the intake manifold runner position sensor, which controls airflow; it’s like the sensor is confused about where it should be.
What the computer is actually seeing
The engine control module (ECM) expects the intake manifold runner position sensor to report a specific voltage range (typically 0.5 to 4.5 volts) corresponding to the position of the intake runner. If it receives a voltage outside this range or inconsistent signals, it triggers the code P2013.
What a healthy reading looks like
The voltage from the intake manifold runner position sensor should be between 0.5V (fully closed) and 4.0V (fully open) with a linear increase as the runner moves. The position should match the angle of the throttle plate within 10% tolerance.
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 for any visible damage to the wiring harness and the connector of the intake manifold runner position sensor. Repair any damage found.
- 22. Using a multimeter, measure the voltage output of the intake manifold runner position sensor while the engine is running. Expect between 0.5V and 4.5V depending on the throttle position. Is the voltage within range?
- 33. If the voltage is outside the expected range, disconnect the sensor and measure the resistance across the sensor terminals. Is the resistance within specification?
- 44. Check the signal ground and reference voltage to the sensor. Is the ground solid and the reference voltage (typically 5V) present?
- 55. If all values check out, you may have a mechanical issue with the intake manifold runner itself, requiring further inspection.
Common causes
- Faulty intake manifold runner position sensor
- Electrical wiring issues (shorts, breaks, or corrosion)
- Faulty engine control module (ECM)
- Mechanical issues in the intake manifold mechanism
Typical repair cost
$$ - $$$ (Sensor: $100-$300; Labor: $100-$150)

Frequently asked questions
Is it safe to drive with this code?
Yes, but performance may be affected and it’s best to address it soon to avoid further issues.
Will this code come back?
If the underlying issue isn't fixed, yes, it will likely return after clearing.
Why does this code pair with P2012?
P2012 and P2013 both relate to the intake manifold runner position, indicating different aspects of performance issues.
