What's Up With My Wideband?

[95TalonOwner]

Well I haven't been around here in a while, usually hang around the local WI dsm forum but I figured I'd see what you guys think.

I think my wideband sensor took a crap but I'm just double checking with you guys. Took this video a while back before winter (car is away for the winter getting a 2.2 stroker right now). Car ran fine when wideband was doing this.

honestly it looks like there is a loose wire because it keeps reading the same afr but its almost flickering. if all of the wires are hooked up good, then id have to say the gauge is on its way out.

 

[Rob10_99]

Is that really flickering or is that the refresh rate on your camera or something?

 

[95TalonOwner]

The wideband is really doing what you see in the video.

I'd check for a loose wire or bad connection as said

Wait, let me rephrase. The flickering is just the refresh rate. Watch the actual number, it jumps around and is not stable. It will be at like 12.9 to 13 and jump all the way lean and go right back.

 

[livedsm4g63]

12.9 to 13 i wouldnt consider a jump. but i know when my car decides to not like me and idle surge, my wide band leans out like your explaining. I cant tell if yours is or is not.

oh. and is it reading like 12.9-13.0 but the color is racing around, back and forth?

It's jumping from 12.9/13 to all the way lean. It's just the gauge jumping. The car idles fine. No idle surge for my 420a.

Hmm, well if all of the wires are connected and they are not loose i would have to say it is either the gauge or the sensor. how long have you had it? and just to be certain, you don't have any huge exhaust leaks right?

 

[95TalonOwner]

No exhaust leaks. Gauge was new about 10-15000 miles ago.

 

[Sp1kE]

No signal makes the gauge read 14.7

 

[livedsm4g63]

im going to say the gauge is at fault.
