P0134 O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 1)

 

i'd say try replacing it...

 

yako don't tell me you bought a caravan to replace the neon

 

ha no its my girlfriends mom van so replacing it ???what will happen if they just ignore it??

 

possibly run rich or lean. and MPG could go down the tube. just go to a junkyard and find a replacement one. i got mine free from a local Pick n Pull yard.

 

so off topic, have you found a replacement yet? At least its newer than my backup, a 95 caravan

 

the PCM might go into limp mode which will make it run like crap and get horrrrrrible gas milage :-\

 

still waiting for the insurance money, when i do i'll def. get another neon but mtx this time any year 00-05 and if i get an atx it'll have to be 03+ and have a sunroof, cant afford an srt at the momment plus i just wanna get out of debt and move somewhere else

 

alright that is cool, just tell the insurance company hurry up
