Incorrect length for 05 Pontiac Vibe
I was able to install this replacement O2 sensor, and it functions as it should. The installation was mostly free of problems, as the threads and plastic plug fit well. Unfortunately, the rubber plug/seal isnt located in the correct spot on the wires, and its permanently affixed. Its about 1.5 inches too close to the square plug, leaving the wires too short inside the car, and a bit too long under the car. I was able to make it work by disconnecting the square plug base from under the dash, but now that kind of flops around up there. The loop under the car is also a bit longer than needed, increasing the likelihood of catching on grass, sticks, debris, etc. Overall the product functions, its just a little annoying when there are only a couple things to get right on a piece like this... or get wrong. I suppose Id buy the part again seeing as its less than half the cost of a factory replacement, but I advise buyers to manage their expectations prior to purchasing.
