What P2589 means
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.
P2589 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2589
- 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
Common causes of P2589
- Most likelyOpen signal or ground wire of position sensor B
- PossibleSignal wire shorted to reference or battery voltage
- PossibleFailed position sensor B
- Less likelyWastegate rod set so the sensor reads at its upper end
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note P2589 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2589
What does P2589 mean?
P2589 means "Turbocharger Boost Control Position Sensor B Circuit High". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P2589?
Drive gently and only to a workshop. With P2589 the car can go into limp mode (reduced power) to protect itself.
Will P2589 fail an emissions test?
Yes, it can. P2589 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2589 to fix?
Difficulty: hard. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P2589 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
