So here is the story. . .2 weeks ago my Wideband sensor wen't bad and was stuck on a 14.8 rating. So I go on and order a new sensor, have it shipped and put it in. Well it was working perfect for about a week and now for some reason it is broke again. It calibrates and stops on - - - on the lean side (like it is supposed to) then I turn the car on and nothing. . .It just sits there on - - - and gives me no AFR reading. I called AEM and they told me to take the sensor out of the bung, turn the key on to accessory and let it sit for about a minute to let it warm up. Then spray brake cleaner on a rag and cover the top of the sensor. If it goes rich then I have other issues but if it stay where it is then it is a bad sensor. Still using 93 at the pump so I don't know.

Any other ideas fellas?

 

how is it mounted, it should be to close to the turbo and it should be at an angle like 10 degrees or the 11-1 oclock position so fluid dont ruin it.

 

Mine is back past my downpipe mounted at a 4 oclock position. . .But my other sensor worked for 1 1/2 years. This one every now and again will look like it is trying to or going to give me a reading but then goes right back to - - -. Grrrrr.

 

i went to ems & mine is mounted in the factory 02 sensor location no problems yet !!!!

 

Mounting the O2 that low made condensation ruin the sensor. Plug that bung and get a new one installed in between 10-1 o'clock.

 

You think it made it go bad that quickly? Even the other sensor lasted a while.

 

Yeah So yesterday i'm at work and had to take a short drive and guess what...My wideband decides to start working. The AFR's were off a little bit but after working for a while they seem to be right on. Guess i'll give it a week or so before I buy a new one. This seems to be an electrical problem so maybe it worked itself out.

 

You run the AEM, right? Make sure the clip that goes on the outside of the connector hasn't come off. That connector comes apart very easily if the clip falls off.

 

Thanks for the tip. I'll check it out.
