Hey!

I have a friend who has the same wideband as me (also drives a evo) and his wideband has stopped working and im not sure what the problem is.

Issue:
It doesnt read properly, it just stays at 15.0-15.3 AFR. It bounces around here and there but WOT, it stays at 15 and trust me, car is running properly. Im sure someone would know right away if it wasnt...BOOOOOOOOOM!

At first we thought it was the gauge then we swapped it out with my buddies EVO X gauge...no dice. Then i was certain it was the sensor. He bought a new sensor last night, installed it...still same problem. I think now it maybe the wiring but im not sure where.

Wondering if anyone has had this issue and maybe point us in the right direction.

Thanks!

 

Were do you have the sensor mounted?

 

downpipe, its been fine from 2007 until like 2 days ago.

 

check over ALL the wiring. maybe it chafed on something.

 

check to see if it is grounded properly if the harness pins are connected clean and properly

 

bad sensor. How old is the wideband? To your comment though, if you were running that lean the car would bog bad.
