95 blazer downstream 02 sensor help!
I need help! So my 95 blazer its ls 4x4 and vin w. I can fully use an obd scanner with live data even tho its they're claimed to be obd1.5 or hybrid...has a p0141 code sensor In bank 2 is malfunctioning(heater). I read many people having this trouble and here am I! Can't find anything but upstream was thinking about searching for 96 and up to find it. Please guys can someone help me figure where and how to get it? Thanks

Your 1995 is in fact OBD1.5 and the downstream oxygen sensor is between the converter and the muffler. DTC's never tell you to replace a part, they tell you what circuit needs to be diagnosed. P0141 is indicating a problem with the heater circuit. With a cold engine, ignition in the run position, engine off, sensor disconnected: Test at the vehicle harness connector: the feed wire must show battery voltage, and the ground wire must indicate less than 5 ohms resistance to ground.
