this is like the 2nd thread i made but i need some help guys. i installed my wideband last week and it seems to not be working right. i got the 10A fuse for power, ground is good, o2 sensor is in the DP replacing the stock one. but its wierd the LED sweep doesnt sweep at all and all i get is wierd numbers like 55.5 6.66 11.1 just back and fourth.


please help!!!

 

aftermarket DP? is that why you replaced the sensor? youre supposed to keep the stock sensor and add the AEM...

 

side not what fogs are those?

 

Where is you 02 sensor located in reference to the cat and horizontal offset?

 

Where is the o2 sensor from......was it your stock one or was it the on AEM supplied?

 

its the aem o2 sensor. i took out the stock o2 sensor from the stock DP and put in the aem supplied one.

 

If it's after the cat, you will get false readings. It has to be before the cat, at least 18" from the head, and 10* above horizontal for it to work right.

 

i should also mention that when i took out the stock o2 sensor my pcm through a CEL "o2 sensor low voltage".

 

That CEL will also mess up your tune and cause the car to dump fuel. You need someone with HPTuners to turn off all the items that'll trigger that CEL for the car to run right.

 

the aem o2 sensor is on my downpipe replacing the stock one o2 sensor. the stock o2 sensor is after the cat too.

 

you should have 2 o2 sensors in your exhaust. You need to remove your downpipe and weld the bung that came with your gauge in the downpipe (for bung location see above posts).

Then when you re-install your downpipe make sure both stock o2 sensor are back where they belong, and the wideband o2 sensor goes into the bung welded into your downpipe. the other side of the sensor goes into your gauge.

 

This thread will come in handy with some pics. I too will be installing the AEM gauge soon. Thanks for the info guys. Need pics!!! Please with a cherry on top...

 

there is AWESOME instructions with the gauge, you dont even need to look at this site, everything is in the booklet.

 

i really do think there is just something wrong with my gauge. i followed the instructions all the way except for the o2 sensor bung weld in. i put the aem o2 sensor in the stock o2 bung on my downpipe just until i could afford a weld or new DP. but even if using the stock o2 sensor position is inaccurate i should atleast get somewhat of a reading but im not. not even a LED sweep. and i know some kids did the same as a inexpensive alternative, whos gauge works 100% regardless wether the reading is accurate or not.

 

The O2 definately needs to go BEFORE the cat. But you're right, regardless of whether you have it in the exhaust port or the muffler, you should never see a reading of 55.5 or 6.66. The guage doesn't even read that far in either direction. Either the guage is messed up or your wiring is off.

 

exactly my point!

 

Ok you need to have a O2 bung welded in after the sensor in the manifold. If you were to just remove O2 Sensor 1 and just plug in your WEGO O2 your car cannot read the A\F ratio and make adjustments.

 

in the manifold?


im guessing everyone with the UEGO here has a welded in bung?

 

I ran mine in the second 02 sensor spot for atleast 3 months and never had false readings. I also had a cat. After the couple months I had it welded in before the cat and the reading didnt change. I think you just got a shitty 02 sensor.

 

What's you're guage flash at startup? Funy no one asked this it has to be set to p00 to function properly with gasoline....

ill post pics today of my 02 sensor location, i had the weld blow out on me last night and ruined my o2 sensor so i have to get a new one, yah it sucks, i used a shitty welder last time and i guess the weld wasnt strong enough, it ran fine for like 2 months though and then pow it just blew, i thought i blew a gasket but i looked under the car and there was my wideband o2 sensor all nice and shinny from dragging on the ground, i was like son of a b***h lol.

also yah my gauge goes, 1.11, 2.22, 3.33 etc etc when you turn the key in the on position and at start up, i think its suppose to do that.

 

p00 is the default setup

thats what i planned on doing. a lot of people have said the same thing 'that it really doesnt make a substantial difference. this ******* sucks

 

whered you buy it from?

 

ng motorsports? i think thats what its called
