Air/fuel gauge stuck?

[st1989]

hi guys,

 

so im narrowing out a few minor issues with the car, split pipes, old intercooler etc and came across a non functional gauge.

ive got an AEM air/fuel gauge fitted to the car, and well, its stuck sitting at 14.8?

the gauge used to vary,

 

it never changes, maybe 14.7 for a min or two then back to 14.8 no matter wether im idling or driving. i did read this could be down to a faulty sensor,

 

if so could this be affecting the car in any other way (boost levels/performance/ or damage?)

 

if anyone could point me in the right direction it would be much appreciated

 

also if anyone knows where i can get a new sensor from? or is it just a case of phoning toyota parts?

 

thanks,

it wont affect anything els , it just reads your mix that is rgulated by your ecu.

 

try thr brake cleaner sensor test.

remove the sensor froim the d/p turn on the ignition to accsesory and the sensor should heat up (dont touch it)

soak a rag in brake cleaner and put it over the sensor a\nd ot should go wayy rich . if it dose great.

if it dosent go verry rich or does for a secont then goes lean , your sensor is goosed

Does it self test alright? Check the plugs on the back of the gauge, if theres no input into the gauge it will stay at stoich (14.7)
