P2589Turbocharger Boost Control Position Sensor B Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2589 means the signal that position sensor B returns for the second boost actuator sits above its plausible maximum, typically from an open signal or ground wire, a short to the reference or battery voltage, or a sensor with a defective output. No manufacturer documents P2589 publicly. For sensor A, GM's 2018 diesel engine table triggers P2565 at an analog value above 95 % in 200 of 250 samples, Type A with the lamp on the first trip, and Kia's service action SA149 for the 2011-2012 Sportage 2.0 T-GDI pairs P2565 with a software update and an adjustment of the wastegate rod until the position voltage reads about 3.8 to 4.1 V. P2588 is the low-side fault, P2565 the same fault on sensor A. Boost is usually reduced.
- What you may notice
- Malfunction indicator lamp on, often on the first trip
- Reduced power with boost capped
- Position of actuator B stuck near the maximum in live data
- Likely causes
- LikelyOpen signal or ground wire of position sensor B
- PossibleSignal wire shorted to reference or battery voltage
- PossibleFailed position sensor B
- RareWastegate rod set so the sensor reads at its upper end
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
