Oil pressure

Asked by Dec 28, 2018 at 12:44 PM about the 2005 Chevrolet Tahoe

Question type: Maintenance & Repair

Yesterday oil pressure went to 80. My husband changed the oil now pressure
is at zero. Could this be the sending unit?

1 Answer


Yes, if the sensor is close to oil filter and he replaced the filter, he may have bumped the electrical connector on that sensor. I have had it happen to me, in the past, on a different vehicle. I just unplugged the sensor and plugged it back in, oil pressure reading was restored. Might be other issues, but that sensor was my first thought.
