So i came home this weekend and i was talking to a buddy of mine that has a 2001 impreza rs. I told him how my uego sensor had failed and he told me that, apparently, the stock o2 sensor on his gen RS is actually the the same wideband that the AEM UEGO kit has you use. I told him about how AEM always says their sensor has the special resistor calibrated for the uego, and he told me that BOSCH made one sensor with that calibrated resistor and it happens to come stock in his impreza rs. I was wondering if anyone else heard of this because i never came across this info before

 

anyone?

 

you should have alok to his sensor and watch the refernce carrefully and then post them here to see if compatible

 

who cares the replacement sensor is 65bucks. the suby sensor is gona be like 500 bucks.

 

no they're roughly the same price, if anything the uego sensor would be more expensive because ppl would assume that sensor is "specially" made, whereas the impreza o2 is a regular maintenance part. but enough of my views of marketing lol. well my friend has a spare and i wanted to see if anyone had come by this info before cuz i want to try his sensor for my uego since mine is fried.

 

I would not just assume that the O2 sensors are identical, especially when tuning. Bosch makes some widebands for VW (probably your cheapest bet) and other makes. The Bosch wideband sensors I have used are linear, so their outputs should read the same at 0-5V.

If the UEGO says it has some special wideband resistor callibration, it may not use a linear output.

 

The only difference is the design of the element's casing/sheild, the connector - and the price. Some elements are more exposed, some aren't. The pricing depends on the design - the more exposed (ever-so slightly faster-reading) cost far more. Connector depends on the OEM.

As for the resistor, all the Bosch O2's have a laser-cut resistor thing that's only used to tell the controller when a different sensor is used. They basicly make all sensors with the same resistor 'plaque', only they choose a random spot to cut it, thus creating a random resistance value.
