Question about 2002 Chevrolet Trailblazer Ext
When I'm driving, and I turn to right the oil pressure gauge goes below to 0 suddenly and then returns to its normal position. I suppose this is a wiring trouble, but I need to know where is located the oil pressure sensor to solve it.
I have this same problem with my 2002 trailblazer; however, I goofed up and had a mechanic look at it, since I was perplexed as to what was going on with it. He told me the oil pump needed replacing and it ended up costing me around a $950. Needless to say, it still happens. A grand down the drain - it wasn't the oil pump. The oil level is always good. This generally occurs when I've run the vehicle for a while and then come to a stop. It occurs quite often during the spring/summer and doesn't happen all that much during colder months.

Usually when oil pressure drops on turns or braking, you need to check the oil level and add oil. It is unwise to permit the level to become that low as each time you turn, the oil in the pan is sloshing away from the pump pickup and starving the system for oil. If level is not low, check that wire for sensor is not chafing against anything and shorting (though generally if that happens, the gauge would read high not low)
