P2564Turbocharger Boost Control Position Sensor A Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2564 is stored when the voltage from the boost actuator position sensor stays below the lowest value a working sensor can deliver, which usually points to a short to ground or a lost reference supply. GM's 2009 Duramax table uses 0.277 V (5.5 %, vanes fully open) held for 1 s once the engine has run 3 s, Type B. Ford's 2023 diesel OBD summary checks the signal continuously against 0.15 V over 2 s, and VW's 2014 Passat book applies the same 0.15 V limit on the 2.0 L TDI and calls it a short to ground. FCA bulletin 09-003-16 for the 2015-2016 Jeep Renegade 1.6 L sold in EMEA lists P2564 with P2565 and replaces the turbocharger. P2565 is the high-side counterpart, P2563 a position error with a usable signal. Expect reduced power.
- What you may notice
- Noticeable loss of power or limp mode
- Check engine light on
- Other sensors on the same 5 V supply may report faults too
- Likely causes
- LikelySignal wire chafed through and touching ground near the turbocharger
- Possible5 V reference supply to the sensor missing or shorted
- PossibleFailed position sensor or vane actuator
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
