What P2C35 means
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engines, together with P2C33/P2C34 and the A-sensor codes; besides wiring and pins it lists a faulty sensor, outdated or corrupted ECM software.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.
P2C35 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2C35
- MIL on
- Crankcase ventilation monitor not completed
- Usually no driveability change
Common causes of P2C35
- Most likelyOpen signal wire or unplugged connector
- PossibleMissing sensor ground (low reference)
- PossibleSignal shorted to 5 V reference or battery voltage
- Less likelyFaulty sensor or outdated engine control software
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2C35 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| C | Area: hybrid propulsion. |
| 35 | The exact fault in that area. |
What to do next
- Note P2C35 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2C35
What does P2C35 mean?
P2C35 means "Crankcase Pressure Sensor B Circuit High". P2C35 is set when the signal of crankcase pressure sensor B sits above the highest voltage the sensor can legitimately produce. It is a generic code, so it means the same on every make.
Is it safe to drive with P2C35?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P2C35 fail an emissions test?
Yes, it can. P2C35 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2C35 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2C35 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
