What does the crankcase ventilation sensor detect?
The PCM needs accurate pressure sensor values to prevent seals and gaskets from getting damaged due to excessive pressure. The sensor also monitors pressure while unburnt fumes go back into the engine via the positive crankcase ventilation (PCV) system.
How does Volvo PCV work?
In naturally aspirated engines, the PCV valve connects the crankcase to the intake manifold. This connection creates a slight vacuum in the crankcase that draws gasses in a direction from the breather into the intake manifold and through the PCV valve, where they are re-burned with a fresh charge of air.
How does a crankcase pressure sensor work?
The Crank Case Pressure Sensor is used to monitor the pressure of the engine oil in the Crankcase, a nd signal a warning if there are any large fluctuations, or if the pressure falls below the minimum or above the maximum indicated pressure.
How do you control crankcase pressure?
Crankcase pressure can be prevented by protecting the piston rings. With a cold start, no oil film is yet present on the moving parts. The chance of metal-to-metal contact increases, so that the piston rings wear faster. This can be prevented with the Lindemann Engine Performance Treatment.
What does a Volvo oil trap do?
A PCV breather system, or oil trap, is designed to reduce the volume of hazardous fumes from a vehicle. As the engine runs, combustion gases escape from the combustion chamber, finding their way into the crankcase. This unused combustion gas, also referred to as blow-by, can be a huge cause of smog.
Where is the crankcase vent valve located?
The PCV valve is often, but not always, placed at the valve cover; it may be located anywhere between the crankcase air outlet and the intake manifold.
How much does it cost to replace crankcase pressure sensor?
The Ford Crankcase Pressure Sensor can run anywhere from around $41 on sale up to around $90 for a new part.
