Exhaust thingy

[1993 NJ LWB]

So after a weekend of 4wding I found this wire hanging down under the paj. Turns out I snapped the sensor off the exhaust(its a lil bit in front of the cat converter). Im guessing its a O2 sensor or some crap. Anyway car seems to be running the same and no engine check light. Do I need to get this fixed or can I leave it or what.

The ECU requires this sensor to adjust the air/fuel ratio. Without it it "should" show a check engine light. As it hasn't I'd say it has reverted back to it's factory defaults. You'll probably notice loss in power and increased fuel consumption, not to mention increased gas emissions
I'd replace it first chance I got

You can usually find replacements on ebay. I bought one from enginesensorsystems for our NM. You need to replace it.

Well funy thing is it broke off wile I was 4wding 300kms from home. Seemed just as powerful and fuel efficient on the way home. But here comes the funny thing the paj used to blow smoke but not since this sensor came off.

Which probably means it was actually faulty before the wires came off.

The O2 Sensor does not come up on the Check Engine dash it only records it in the log.

You might not notice a power difference, but you will notice your fuel consumption abit more and a sulphur smell from the exhaust. A O2 sensor lasts about 100 000Kms, Just like a spark plug, this aswell needs replacing at a certain time. You should replace this as soon as you can. They normally go for about $90 for a Bosh one at auto spare parts shops.

how many O2 sensors on the NM?

One, down underneath after the two engine pipes join. Fairly easy to get at and replace.
