After the issues with trying to remove my sensors that are dead.

Two options i need a bit of tech help with.

What causes them to die, have i have cleaned the connectors but still nothing?

After chatting to Bee Gee Vinz, he had his relocated, im thinking of putting them further down the pipes, to make more accessible from under the zed. if doing this, what size nut do i need to weld onto the pipes aqnd where is best to situate them.

Anyone else done this.

Firstly what causes them to die is simple, age! They are not designed to last for ever and i would expect somewhere in the service schedule they should be replaced, i know other cars do. That's why it's becoming more common on here to see peeps having issues with their 02 sensors, our cars are now 20 years old at worst. I would suggest anyone who has an engine removal for what ever reason, replaces them whilst it's really easy to do, knackered or not.

As for moving them, well yes you could, but bare in mind they are placed where they are meant to be to make them most effective, close to the turbo.

The sensors are constantly sending signals to the ECU, that signal is effected if you remove them, disconnect them or move them. Whilst they work for the emissions and cat convertors at the same time. The primary role is tell the ECU what air/fuel mixture to run. The mixture is extremely rapid in it's changes and these changes are based on what the 02 sensor is telling it.

For the odd few who have them disconnected and say, "well mines okay" how do they know? unless you are running something like a conzult as you drive and know what it should actually read, you won't know!

Though it does cause running rich and poor fuel economy.

Phew :) hope that helps, lol

Had mine installed high up the aftermarket down pipes by JP Exhausts in Macclesfield who originally built my exhaust.Never had a problem,but as I have a Techtom I can check on their functioning correctly.Been installed a few years now and are dead easy to change from underneath the car.
