In this video, I show you the exact location of the Cylinder Head Oil Pressure Sensor (often associated with the variable valve lift or VVT system) on a 2012-2016 Chevrolet Malibu 2.5L. Pinpointing exactly where this sensor is threaded into the cylinder head is an essential first step for a smooth DIY vehicle repair, saving you time and helping you navigate the components on the side of the engine.
Common symptoms of a faulty Cylinder Head Oil Pressure Sensor include:
- An active Check Engine Light (CEL) or a “Low Oil Pressure” warning message on your dashboard, often triggering specific codes like P5068 or P0520.
- The engine dropping into a “limp mode” or experiencing reduced engine power, preventing the variable valve lift system from engaging properly.
- Erratic engine performance, hesitation during acceleration, or visible engine oil leaking into the sensor’s electrical connector.
Safety First: Working around the cylinder head and hot oil passages requires standard automotive precautions. Always ensure the engine is completely off and cool, protect your hands and eyes by wearing durable gloves and safety glasses, and stay fully focused and attentive throughout the entire job.
