P2B60Engine Coolant Flow Control Valve Position Sensor Circuit Range/Performance

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
  • Needs a drive cycle to confirm a fix
How the car detects it
P2B60 checks whether the valve actually goes where it is told. On GM's 3.0 L Duramax the code sets when the gap between desired and measured position exceeds 12 % in 160 of 200 samples, only with a steady command, closed-loop control active and no coolant or outside temperature sensor fault (Type B). For LM2 trucks and SUVs GM issued 20-NA-039 and 22-NA-082 (ECM software), PIP5764 (corroded terminals at the centre actuator connector) and PIP5791, which has the valve swept from 25 to 95 % with GDS2 and then relearned. Hyundai and Kia link P2B60 to the cleaning routine of the ITM module on 1.6 T-GDI engines (23-EE-002H, 24-FL-003H, Kia ELE 285) and fix it with software.
What you may notice
  • MIL on after two drives
  • Engine temperature fluctuates or warms up slowly
  • Often no driveability complaint beyond the warning lamp
Likely causes
  • LikelyEngine control software (GM 20-NA-039 / 22-NA-082, Hyundai/Kia ITM logic)
  • PossibleCorroded terminals at the valve actuator connector (GM PIP5764)
  • PossibleValve sluggish or not learned, needs a relearn after test
  • RareValve does not follow commands although wiring is fine
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
