my check engine light came on so i checked the code. the code came out to be 41. i have this paper that said code 41 is the
preliminary heated o2 sensor or something like that. where is this located, is it the one thats on the headers or what?

don't i knwo you? switch trannys yet? haha. go to:
http://tech.hybridgarage.com/tech/index.html
there you will see everycode for your car.
and the O2 heating wire is jsut in the O2 sensor. which is right in the exhaust mani. this stupid thing with wires going into. caution, may be hot if car was running. haha

41 :
Primary Oxygen Sensor - Heater
circuit malfunction
go buy a new O2 sensor dude. cheap as hell.

i haven't put the new tranny in yet. is this sensor the one that goes into the headers? i thought $70 was expensive for this sensor, or am i looking at the wrong one?

it might be disconnected by accident.
go under and check.

well, it depends. if you find a used O2 on here, it will be cheap. but yeah, new O2 are expensive. but used O2 work the same.

well, here's whats going to happen. i'm going to try and find a used o2 sensor, if i don't find one, i'm just going to buy a new one. we are just going to install the tranny ourselves sunday morning, we need to learn how anyway for when ever
we need a new clutch. i'm just going to use the money for the tranny install to buy the sensor. i may head out to a junk yard sat to look for some stock mirrors, should i try to get a sensor from them?

find a car with the sensor, then go in there late some night and get it!
what O2 sensor do you need? I might have 1 laying around here somewhere.

B_1_8_hatch

its the primary one so i'm thinking its the one that goes right into the headers.
let me know if you have one.

you have a primary and secondary O2, right? or not. let me know. and what year is your ls? I have a gsr O2 here. becasue my 99 gsr has a primary and secondary O2, but I only used 1. (no cat) and theres only 1 plug for both O2's so I just wired the 1 O2 up. maybe you can see if you can bypass the primary and hook those wires up to the secondary. do you understand what I mean?

i have a 93 hatch dx. i'm not sure if i have one or two o2 sensors. i will look tonight when i get home. the code is 41 - primary oxygen sensor heater.

thats teh same code I had in mine. switched O2 sensors, and it was perfect.

B_1_8_hatch

is that the one that right on the headers?

I think so. i dunno. it looked like a spark plug with wires coming out of it. takes a 7/8 wrench to take it off. my O2 sensors were after the exhaust manifold. on the cat. jsut take a look. its the only thing in the exhasut with wires coiming out of. can't miss it.
