Are the TT and N/A oxy sensors the same?

 

Also is there any option of aftermarket o2 sensors? Ive heard some banter about wide band sensors but no idea what they are / how they would fit in to a zed

Well Courtesy list them as different mate with the N/A being dearer.

Wideband sensors are used when tuning cars and generally you won't find them as a stock item on a car, I beleive if in constant use they can burn out more quickly. You would normally drill another plug hole for a wideband sensor, fit the sensor and use it for tuning and then remove and fit a blank plug when not in use, so erm in short, stick with stock :D

Cheers mate, ive got a lazy left hand o2 sensor, but are these worth swapping in pairs?

Well certainly if 1 has gone down or playing up, unless the previous owner changed just 1, I would swap em both.

Yer looking at an average of 15 years of use for these and not a great cost to replace either, an average 120 quid a pair for peace of mind based on their role :)

Wideband sensors are no use in place of a narrowband sensor. The output voltages are different and the ecu has to be able to read and use the wideband info.

I had one as a stand alone item, showing a/f ratios on a gauge when I mapped my ecu.

Then later on I reprogrammed the ecu so the wideband sensor controlled the mixture also.

There are a few cars using them as standard now and pretty soon most new cars will have them. That's why the price has plummeted over the last few years.

As a stand alone extra, with the gauge, they are a brilliant tuning tool. Dead accurate and instant readout with no delay.
