P2562
Turbocharger Boost Control Position Sensor Circuit
Severity
medium
Worth booking. It costs fuel, emissions or comfort until it is fixed.
Can you drive it
Only if running normally
A short trip to a shop may be reasonable if the light is steady and the car runs normally. Stop safely for a flashing light, severe shaking, overheating, loss of power, or another urgent warning. The code alone cannot confirm safety.

Wastegate or variable-vane position sensor circuit fault.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then work the likely-causes list in the order shown.
That order is what a shop checks first for this code — wiring and connections before the component they run to, because a connector costs nothing to inspect and is a common answer.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

P2562 means the ECM/PCM is reading the turbocharger boost-control position-feedback sensor on actuator A (typically the VGT vane-position sensor on diesel applications or the wastegate-position sensor on modern gasoline turbo applications) at a voltage below the lower limit — usually below about 0.5V on a sensor with a normal 0.5-4.5V scaled output range. The sensor reports the physical position of the variable-geometry vanes or wastegate flap back to the ECM as a closed-loop feedback signal so the ECM can verify that the commanded position is actually being achieved; a low signal means either the sensor itself has failed shorted-to-ground, the signal wire is shorted to ground in the harness, the 5V VREF feeding the sensor has dropped or opened, or the actuator is physically stuck at the low-position mechanical stop.
Cheapest-first ladder
- scan live data with the engine warm at idle, the actuator position PID should report something in the 0-30% (or 0.5-1.5V) range at idle and climb toward 50-100% (3.0-4.5V) under boost-building command; back-probe the 5V VREF at the sensor connector (must read 4.9-5.1V key-on); back-probe the signal wire at the same connector (should sweep 0.5V through 4.5V as the actuator is commanded — bi-directional scan-tool actuation makes this a 5-minute test); verify the sensor ground is below 0.1V drop to battery negative; physically inspect the actuator linkage for binding, soot/coke buildup, or a snapped unison ring on a VGT — diesel VGTs cake up with soot every 80,000-120,000 miles and the vanes stick in the low-restriction position, throwing P2562 because the sensor correctly reports the stuck position.
- Before condemning the actuator or sensor, ALWAYS verify the 5V VREF and ground at the connector — a shared-VREF fault that also drops the MAP or pedal-position sensor reading makes the cheap fix a harness repair, not a $800-$2,500 turbo actuator.

- 2003-2007Ford 6.0L Powerstroke is the king of P2562 — the VGT vanes coke up from EGR soot and the unison ring binds, requiring a turbo-out clean or full VGT replacement; the position sensor itself is rarely the failed part, the mechanical bind is.
- 2008-2010Ford 6.4L Powerstroke (twin-sequential turbos) throws P2562 on the high-pressure (VGT) stage from the same soot-induced binding pattern.
- 2011-2019Ford 6.7L Powerstroke (Scorpion) throws P2562 from a redesigned VGT that fails electronically (the actuator is a smart actuator with an internal motor and position sensor as a single replaceable assembly).
- 2007-2010GM Duramax LMM 6.6L throws P2562 from VGT vane soot-binding on the same pattern as the 6.0 PSD.
- 2011-2016GM Duramax LML 6.6L throws P2562 from the same VGT carbon-binding plus actuator-internal position-sensor failure on high-mileage trucks.
- 2007-2018Cummins 6.7L (Ram 2500/3500) throws P2562 from VGT actuator-internal failure — the Holset HE351VE actuator is the replaceable assembly.
- 2011-2016BMW N20 2.0T and N55 3.0T turbo gasoline applications throw P2562 from wastegate-position sensor failure inside the electric wastegate actuator.

What does a P2562 code mean?
Wastegate or variable-vane position sensor circuit fault.
What causes a P2562 code?
Common causes: Failed position sensor; Stuck actuator; Wiring.
What are the symptoms of a P2562 code?
Typical symptoms: Check engine light; Reduced boost; Loss of power.
Is it safe to drive with a P2562 code?
Only if running normally. A short trip to a shop may be reasonable if the light is steady and the car runs normally. Stop safely for a flashing light, severe shaking, overheating, loss of power, or another urgent warning. The code alone cannot confirm safety. Estimated repair: $200-$1,800.
How do I diagnose a P2562 code?
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed. 1. Note every code that is set, not just this one. 2. Read the freeze frame — the conditions the fault was recorded under. 3. Confirm the fault is current rather than history. 4. Then work the likely-causes list in the order shown.
