P2014 Code: Intake Manifold Runner Position Sensor (Bank 1)
The flaps might be moving, but the computer can't "see" them. Learn how to diagnose sensor circuit failures.
1. What Does P2014 Mean?
The code P2014 stands for "Intake Manifold Runner Position Sensor/Switch Circuit Bank 1."
To control airflow precisely, your car's computer (ECU) needs to know exactly where the intake flaps are at all times. It relies on a Position Sensor (usually a Potentiometer) to send back a voltage signal indicating the flap angle.
P2014 means the circuit for this sensor on Bank 1 has failed. The computer has lost its "vision"—it sends a command to move the flaps, but it gets no feedback confirming they actually moved.
👀 The Eye vs. The Muscle
It is easy to confuse P2014 with P2008. Here is the difference:
- P2008 (Actuator): The "Muscle" is dead. The motor cannot move the flaps. Read P2008 Guide.
- P2014 (Sensor): The "Eye" is blind. The motor might be working fine, but the sensor isn't reporting back.
However, if the sensor fails, the ECU will often disable the system to prevent damage, which can lead to mechanical codes like P2004 (Stuck Open).
3. Why Did the Sensor Circuit Fail?
On Volkswagen (TSI/FSI), Audi, and Mercedes engines, this is a frequent issue. The causes usually fall into three categories:
- Sensor Wear: The position sensor is a mechanical wiper sliding on a resistor track. Over 100,000 miles, the track wears out, creating "dead spots" where no signal is sent.
- Wiring Damage: The wires connecting the sensor to the ECU are thin. Vibration or heat can cause an "Open Circuit," cutting the signal.
- Connector Corrosion: Oil leaks or moisture can get into the sensor plug, causing resistance values to drift out of range.
4. How to Diagnose with Live Data
Since the problem is that the ECU "can't see," you need to use a scanner to act as the ECU's eyes. You need the iCarsoft CR Ultra P.
The "Sweep Test" Workflow:
- Setup: Connect the CR Ultra P and go to Live Data > Intake Manifold Runner Position Bank 1 (Look for Voltage or Percentage).
- Engine Off, Key On: The sensor should show a steady value (e.g., 0% or 0.5V).
-
Manual Move (if accessible): If you can reach the actuator arm, move it by hand.
- Good Sensor: The voltage on the scanner screen should change smoothly as you move the arm.
- Bad Sensor (P2014): The line on the screen stays flat or drops to 0 instantly.
- Rev Test: If you can't reach the arm, start the engine and snap the throttle. The position value should jump. If it stays flat, the sensor circuit is dead.
See What Your ECU Can't
Don't just replace parts. Use the iCarsoft CR Ultra P to graph the sensor voltage in real-time. If there's a glitch in the signal, you'll see it on the screen.

Q: Can I replace just the sensor?
A: It depends on your car. On many older Fords, yes. But on modern VW/Audi 2.0T engines, the sensor is often integrated into the intake manifold or the actuator motor, requiring you to replace the whole unit.
Q: Will P2014 affect my driving?
A: Yes. Without position feedback, the ECU will usually lock the flaps in a "safe" position (open), leading to loss of low-end torque and poor fuel economy.
Q: Where is Bank 1?
A: Bank 1 is the side of the engine with Cylinder #1. P2014 affects this side. If you have a V6/V8 and the problem is on the other side, you will get Code P2019 (Bank 2 Sensor).
