P2C35Crankcase Pressure Sensor B Circuit High

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
How the car detects it
P2C35 is set when the signal of crankcase pressure sensor B sits above the highest voltage the sensor can legitimately produce. That usually means an interrupted signal wire pulled up inside the module, a broken sensor ground, or a short from the signal to the 5 V supply or to battery voltage. Maserati names P2C35 in bulletin MAS002969/A, on the MY21 blow-by sensor of the F160 six and F154 eight-cylinder engines, together with P2C33/P2C34 and the A-sensor codes; besides wiring and pins it lists a faulty sensor, outdated or corrupted ECM software. Ford's analogue sensor A uses P051D above 4.56 V for 5 s as its counterpart. Because the ventilation monitor depends on this signal, the MIL lights even though the engine runs normally.
What you may notice
  • MIL on
  • Crankcase ventilation monitor not completed
  • Usually no driveability change
Likely causes
  • LikelyOpen signal wire or unplugged connector
  • PossibleMissing sensor ground (low reference)
  • PossibleSignal shorted to 5 V reference or battery voltage
  • RareFaulty sensor or outdated engine control software
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.

Medium · Often possible to do yourself.Typical cost: €50 – €400
