P2C32Crankcase Pressure Sensor B Circuit

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
How the car detects it
A crankcase pressure sensor tells the engine module how the pressure in the crankcase ventilation compares with ambient, mainly so it can detect a disconnected or leaking breather line. P2C32 is the general circuit fault of sensor B: its signal is missing or cannot be decoded at all, without saying high or low. No manufacturer documents this exact code publicly. Ford shows the pattern for sensor A: on digital SENT sensors, invalid frames or signal patterns set P051A within 5 s, while analogue sensors report the range, low and high codes. Maserati lists the B codes P2C33–P2C35 for the blow-by sensor of its 2021 V6 and V8, but not P2C32. CARB requires the ventilation system to be monitored; with the sensor down that check cannot run, so the MIL is to be expected.
What you may notice
  • MIL on
  • Crankcase ventilation leak check not available
  • Usually no change in driveability
Likely causes
  • LikelyUnplugged, loose or corroded sensor connector
  • PossibleOpen or chafed wire between sensor and engine module
  • PossibleSensor electronics failed
  • RareEngine module input or software fault
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
