I have a 2008 Chevrolet Trailblazer LTZ 5.3L V8 140,000 km. Two days ago when I started the car and began driving, I noticed the “Check Gauges” light had come on and the oil pressure gauge needle was exactly at 0. I immediately stopped my car and shut down the engine to check the oil level which was absolutely fine. I wasn’t sure what to do, so I carefully drove to my destination without any problem. There was no engine power issue or any other noise. There was no engine oil warning light or any message like “oil pressure low” on the driver information center. Everything seems to be fine except the “check gauges” light and the oil pressure gauge reading. I have driven more than 300 km since then. What should I do?:x

The oil pressure gauge s fake, meaning it only shows what is programmed inti the bcm. It is not accurate by any means. More than likely, you need to replace the oil pressure sender. FWIW, my tb idles at 7psi by the mechanical giage I installed while the dash gauge shows 40 psi.

The OP has a V8 and has a real oil pressure sensor that measures actual pressure.

Agree, sensor should be changed.
