Default 2017 Chevy Silverado O2 Codes
I have a 2017 Chevy Silverado with 53,000 miles. I have a 5.3L engine. I had codes P0138 & P0158 pop up today for the O2 sensors. One is bank 1 sensor 2, and the other is bank 2 sensor 2. I find it weird for two sensor to fail at once. Anyone ever see this or have any other insight before replacing both sensors?
