anyone... the car is on jack stands 1 and i am looking to get it down

[boozy]

i thinks that it is the exhaust temp sensor, but do i neet it or can i leave it unmountet and just plug a bolt in the hole?

[Shusaka]

that, sir, seems to be an O2 sensor wire, thats not supposed to be in two peices and you will need a whole new sensor

[boozy]

hehe i now i need a new one, but can i drive without it?!? an what do that **** cost im tripping to drive with the new exhaust... wroooom

[Shusaka]

yeah youll throw a check engine light with that OBDII haha 95>96 i love my OBDI zenki, and you also may notice ****tay fuel economy, or really rich fuel, long story short, if you can deal with the check engine light and a real pisssed off EPA, then yes drive your heart out

[boozy]

i also have a zenki, but with kouki front conversion, but when i searched for new o2 sensor the sensors seems bigger that that one what was in...

[boozy]

sure about that it is a o2 sensor:

is that sensor not right behind the turbo?!?

btw i have a light in the speedo that shows a engine where it stand check on, how do i find out what i could be that lightings the that signal?

Man he just told you its the o2 sensor, he even drew you a circle around it. AND he also told you that it throws a code, read man!! There are two o2 sensors, one in the exaust downpipe, and one after the cat.

[boozy]

its hard when someone on a other forum told me that it is a exhaust temp sensor, and for me its not looking like a o2 sensor... hmm

I dunno guys, but that doesn't seem to be an OEM CAT or sensor.... when did nissan use a braided cover over the oxygen sensor wire?

the shiny straight test pipe that's polished to a high gloss gives it away; maybe it is an exhaust temp sensor <shrugs> cause I also don't see the hex points to put a socket/wrench to turn it out

to the OP, do you have an OBD II port? plug a scanner in there and let us know what the code is already

[boozy]

HA you see ont an o2 sensor, how should a solid metal heap messure lamda numbers? its have no holes in it, but anyways there was no cable in it, just that metal think that should be slipped over the think again, just saw it as i took the sensor out...

i have nothing at all to find out what the lamps is saying, but should i go for the guide to find out the code with led?!?

since you are in europe i would assume that is a factory sr20 silvia.Idk restrictions on emissions in europe, but that may not have an obd2 setup?Get on some of your european forums and research there.

the car is importet from Japan

Its an aftermarket temp sensor, see how the wire runs thru the floor instead of towards the lower transmission harness.

i have driven the car today and there the light is not lighting, but should the engine check lamp not go out befor crancking the starter? shoulded on my civic

pull the grommet off and take a look at the wire color

is it a blue yellow wire? if so, its a exhaust temp sensor.

the o2 sensor is right behind the turbo.
