1999 chevy blazer ,4.3, 4x4 / code po135
hi guys ! I have a 1999 Chevy blazer, 4x4, 4.3 and it's throwing a po135 code, which is a oxygen sensor ! it reads 02 sensor, bank 1, sensor 1, upstream, before the cat ! I checked auto zone and Denso sensor says no heated and Bosch says heated ! I like to know which one to buy, a heated one or non heated ? I looked at the picture and it shows 4 openings on the plug-in so I assume it has 4 wires ! so the upstream, bank 1, sensor 1 is heated or not ? thanks guys !
