Hey fellas. Had my car up on the hoist the other day and did my Engine, Gearbox and DIFF oils. Were all black and put good fresh stuff in em.

However while the car was up on the hoist i noticed a sensor coming out of the cat. Which had tape over it.

I believe this sensor is the EGT (exhaust gas temperature sensor). The tape was around the 2 coils of wires in it and i think its rooted..

The car is running heaps rich so i thought i should give replacing this sensor and the O2 sensor at the same time.

Where abouts would i get an EGT sensor from. The O2 isnt a problem.

Could this be the reason. Cos its faulty... and its dumping more fuel in to cool the exhaust down???

Cheers Blokes.

egt isn't a problem unless the cat convertor light is on the dash.. does your cat convertor have a bung to mount it to? as alot of cats fitted for compliance don't thats why u'll find alot not hooked up. as for running rich stick a multimeter on your o2 sensor signal wire and check the voltage at idle when warm. it should fluctuate between 0 and 1v. if it is stuck on around 0.5v it is stuffed and this is why ur car is running rich..

Umm the car has a nismo dump, and down pipe.. but from cat back its all pretty much stock standard.. I think the EGT sensor is effffed. As the 2 wires that it has were taped together and yeah.. just looks rooted if u know what i mean,

And as for the O2 Sensor. Which wires am i putting the multimeter as is has 3.

I shall check for this problem.

Would the coolant temp sensor have anything to do with this?

Cheers.

teh egt doesn't effect the tunning of your car

it just lights up to tell you your cat is still really hot (been doing some 'fun' driving) and not to park on anything flammable

o2 sensor on the other hand will effect economy, just grab one from this sponsor:

      New fix for low tyre pressure from bmw

      Yep, pretty much what you said is a good summary. The aftermarket thing just attached to the rim, then has two lines out to valve stems, one to inner wheel, one to outer wheel. Some of the systems even start to air up as you head towards highway speed. IE, you're in the logging tracks, then as speeds increase it knows you're on tarmac and airs up so the driver doesn't even have to remember. I bet the ones that need driver intervention to air up end up seeing a lot more tyre wear from "forest pressures" in use on the highway!

      Anyone know this frontpipe?

      Yes, but you need to do these type certifications for tuning parts. That is the absurd part here. Meaning tuning parts are very costly (generally speaking) as well as the technical test documentation for say a turbo swap with more power. It just makes modifying everything crazy expensive and complicated. That bracket has been lost in translation many years ago I assume, it was not there.

      Hahaha, yeah.... not what you'd call a tamper-proof design.... but yes, with the truck setup, the lines are always connected, but typically they sit just inside the plane of the rear metal mudguards, so if you clear the guards you clear the lines as well. Not rogue 4WD tracks with tree branches and bushes everywhere, ready to hook-up an air hose. You can do it externally like a mod, but dedicated setups air-pressurize the undriven hubs, and on driven axles you can do the same thing, or pressurize the axles (lots of designs out there for this idea)... https://www.trtaustralia.com.au/traction-air-cti-system/  for example.... ..the trouble I've got here... wrt the bimmer ad... is the last bit...they don't want to show it spinning, do they.... give all the illusion that things are moving...but no...and what the hell tyre profile is that?...25??? ...far kernel, rims would be dead inside 10klms on most roads around here.... 馃槂

      You're just describing how type certification works. Personally I would be shocked to discover that catalytic converter is not in the stock mounting position. Is there a bracket on the transfer case holding the catalytic converter and front pipe together? If so, it should be in stock position.

      You talking about the ones in the photo above? I guess that could make sense. Fixed (but flexible) line from the point up above down to the hubcap thingo, with a rotating air seal thingo. Then fixed (but also still likely flexible) line from the "other side" of the transfer in the hub cap thingo up to the valve stem on the rim. A horrible cludge, but something that could be done. I'd bet on the Unimog version being fed through from the back, as part of the axle assembly, without the need for the vulnerable lines out to the sides. It's amazing what you can do when you have an idea that is not quite impossible. Nearly impossible, but not quite.
