P2015Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance (Bank 1)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P2015 means the position feedback of the intake manifold runner or swirl flaps on bank 1 is electrically present but implausible. How it is judged depends on the design. Diesels with a smart swirl actuator send position as a pulse-width signal: GM's 2018 diesels fail a pulse period below 0 or above 64 ms in 52 of 62 samples (Type B), and on the Opel/GM 2.0 CDTi in the Saab 9-5 (2010) the ECM flags a wrong frequency from the actuator, with sub-codes for period and high and low time (Type A). Ford's petrol engines call it position sensor over travel. Audi and Volkswagen use it widely on 2.0 TFSI: a corroded flap valve N316, a flap that separated inside the manifold, and on the 4.2 FSI a deformed seal behind the flap potentiometer that made the linkage stick. After a manifold or valve replacement the flap adaptation has to be run, or the code returns.
- What you may notice
- Malfunction indicator lamp on
- Rough idle or weaker low-speed torque
- Likely causes
- LikelyFlap linkage sticking or flap separated inside the manifold
- PossibleCorroded or faulty flap control valve
- PossibleActuator electronics or position sensor faulty
- RareFlap adaptation not performed after repair
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
