In this video, I show you the exact location of the Engine Oil Pressure Switch (also referred to as the oil pressure sending unit or sensor) on a 2014-2020 Chevrolet Impala 3.6L. Pinpointing exactly where this switch is located on the engine block is a critical first step for a smooth DIY vehicle repair, saving you time and helping you navigate the tight spaces near the oil filter housing.
Common symptoms of a faulty Engine Oil Pressure Switch include:
- The oil pressure gauge or driver information center on your dashboard displays wildly erratic, fluctuating, or zero-pressure readings.
- A persistent “Low Oil Pressure” warning message or a Check Engine Light (CEL) illuminating on your dash, even though your engine oil level is completely full.
- Engine oil visibly seeping or leaking through the switch’s electrical connector or mounting threads.
Safety First: Working near the oil filter assembly and lower engine block means dealing with tight spaces and potentially hot engine oil. Always protect your hands and eyes by wearing durable gloves and safety glasses, ensure the vehicle is safely supported on jack stands if accessing from underneath, and stay completely focused and attentive throughout the entire job.
