Good To Know

Q: How do I test an oil pressure switch? A: Use a multimeter to check continuity when pressure is applied; the switch should close or open at the specified PSI according to your engine's specs.

Q: What happens if an oil pressure switch fails? A: It may cause a false low-pressure warning or fail to alert during actual low oil pressure, potentially leading to engine damage if left unchecked.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
