P2017Intake Manifold Runner Position Sensor/Switch Circuit High (Bank 1)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P2017 is the mirror case of P2016: the bank 1 flap feedback is stuck near the supply rail. With a pulled-up input that happens when the signal or sensor ground opens, or when the signal wire touches a voltage source. Ford's limit is 4.7 V for 5 s, Volkswagen uses 4.85 V on the 3.0 TDI and 4.88 V on the 3.0 TSI hybrid of the 2014 Touareg. On GM's 2018 diesel swirl actuator the period is again pinned at 30 ms but the duty cycle reads 100 %, counted in 50 of 62 samples; the 2025 SENT version flags a raw value over 99 % in 480 of 600, both Type B with MIL after two trips. Chrysler's short runner valve bulletins cover P2017 together with P2016, which points to shared supply or connector faults rather than two failed parts.
