My AEM wideband was working fine before my recent engine tear down. I did not touch any of the wiring to my ECU or any wiring that has to do with the gauge for that matter.

The only things I did regarding the sensor was unplug it from the connector at my downpipe and remove the sensor from the downpipe as well.

Reinstalled sensor and connector after the motor was dropped back in and now it stays at 14.7 at all times.

thoughts?

I suppose it should also be noted that I uploaded a stock p28 to my s300 and didn't touch anything in the tune beside which MAP sensor I have. Do I have to change anything in hondata?

 

Does the actual aem uego gauge say 14.7?
If so, make sure the sensor is properly plugged into the harness & the harness if plugged into the back of the gauge.
If that is not the issue try another sensor.

 

yea the gauge only displays 14.7 and thanx, will do.

 

^^exactly what a Tech at AEM would say!

 

Exactly what they would say because that is most likely the problem. If the sensor was bad it would at least be doing something. When the sensor is unplugged however the gauge will read 14.7 Meaning only two things the sensor is not plugged in properly or the wiring from the back of the gauge has come loose.

 

all the wiring is good, now what??

The sensor probably went bad.
