I have a 2005 Envoy Denali I gradually lose oil pressure

Customer Question

I have a 2005 Envoy Denali I gradually lose oil pressure according to the gauge on a dash goes 40 and slowly drop almost 0 as I go it picks up and if I come to a standstill it drops down almost to zero where the check engine light come on. Took it to Autozone the code said it was the oil pressure sensor I replace the sensor and it did the same thing again don't know what the problem is. Vehicle seems to be running fine its not knocking im just too scared to drive with the pressure low. what else should I check?
JA: Thanks. Can you give me any more details about your issue?
Customer: The vehicle drives good I replace the oil pressure sensors 2 different times the gauge still fluctuate sometimes now and then drop down to almost zero when i come to a stop when i speed up it'll pick up more pressure .
