Like the silvertop ppl dont use o2 sensors awa...lol
i saw some youtube videos and read online alot of ppl using zirconia sensors on their silvertop.
i installed a Denso 234-4072 Oxygen Sensor (zirconia) over the weekend, had to widen the flange holes a bit to get it to fit, and wired it up. no exhaust leaks, no cel codes and by using a multimeter am seeing the the voltage swing. car feels a bit better, have not tried it out on the road yet to see if fuel economy has improved. ill report back when i do but am wondering though, how do you really know when the ecu is actually using the sensor signal to trim fuel? the voltage swing i saw is coming from the sensor, how do i know the ecu is accepting the signal from the sensor?
any thoughts on this?
