anytime the sensor is not sending a reading to the gauge it stays at 14.7-14.8.....

there is no error thing that pops up or anything

 

I have the same problem...however a week or two ago...it was stuck on the (---) lean. Now it stays on 14.8 and sometimes goes to 15 but it always come back to 14.8 ans stays stuck there.

I ordered a new sensor cuz I thought the sensor was the problem when I first saw the (---) (the car was running perfectly and is still running perfectly, no stalling or any other sign of problem)

I guess I'll go check if water in the plug is my problem too.

 

I was having the exact same problem for 5 months last week my gauge decided it wanted to work right again for a few days and now its back at 14.8 so I know its not my sensor. Im prob just going to give in and buy a new one.

 

check to make sure the sensor is actually clipped in. i ordered a new sensor because i thought mine died, and when i got under the car the plastic clip was loose, i plugged it back in and it started working again... idk how it got loose over time but its always a possibility

 

I started my car yesterday and noticed my gauge is also stuck at 14.8. The sensor is pretty new and never had any problems like this before. Wtf

 

My gauge is still reading 14.8. Should I replace it????

 

I have a problem with my AEM UEGO too. It does not match the AFR reading that the wideband at the dyno was giving. The one at the dyno is a steady good number. When I go WOT, my UEGO goes to 10.8 or flat to 10.0. The gauge is sharing ground and power wires with the clock and all the other gauges I have. Should it have a seperate power feed to reduce any possibility of noise affecting the reading? Is the sensor bad? It is only a couple months old.

 

Undo the harness and clean the connectors....both halves and plug her back in.

 

I would examine how the dyno's wideband first. 1.) where is it located in the exhaust? Is it in a bung or a sniffer on the muffler? 2.) Dyno widebands generally see alot of race fuel which contain lead, shortening the sensors lifespan. I would generally not trust the in house wideband and rely on your own which sounds like is more sensative.

 

To all with the 14.8 reading check the two harnesses that plug into the gauge itslef. My problem turned out to be the orange wire had pulled free from the plastic clip from vvibrations over time I guess and was not getting good contact. Hope this helps some of u check all the wiring that goes into the white plastic clip and make sure the pins are in there securely

 

Man, I have to say, I've never heard of so many wideband problems until more and more people started using AEM's...... certainly makes me curious.

Normally when 02 sensors fail they read lean, that has been my experience...

 

Innovative and never look back. Went threw 2 aem's before getting one

 

More and more people are using "--thanol" and lead fuels and those will shorten the life span of the sensor. IIRC, every company uses the same sensor, a Bosch.

 

lol

 

What do you mean by "Innovative"? So some ideas here are very innovative ?
