The oil pressure switch and sensor indicates if the oil pump and lubrication system are working properly, detects if the pump or relief valves are stuck open, senses if there is insufficient oil, and provides inputs that determine the useful life of the oil.
OE capacitance designs fail when the connection between internal plates and films fracture.
OE sensors can create electrical noise or be susceptible to other engine noise, causing inaccurate readings.
Failure Modes
Oil Leaks
Erratic gauge operation
Total electronic failure with the gauge reading zero or very high
Solution:
ISUMO piezo-style designs produce no extraneous noise and are less susceptible to electrical noise in the engine compartment.
ISUMO units feature multiple glued seals, oil-resistant o-ring gaskets, and thread sealant is applied to match OE.
Dual sealed to prevent leaks
Low susceptibility to RFI
Extended life

ATTENTION
Variable valve timing components work best and most efficiently when the engine oil
is clean and clear of debris. Please ensure that you are using the correct oil viscosity
and perform the required oil change when replacing VVT components.
