whats up...i hooked my air/fuel gauge up in my crx today...it turns on but dosen't read???just sits in rich...i have it hooked to the only wire on my o2....i searched but i couldn't fine anything on a crx...

thanks

 

you could try the wire right on the ECU it is pin #16 on the "C" plug it is yellow if I remember right

Is this at idle when you start it? Run the car until it warms up and you will see it change. At cold start it always reads rich because of open loop mode or is it closed loop mode (always get them mixed up).

 

Have fun watching the light show. Get a wideband if you want an accurate air/fuel reading that can actually help you.

 

its ok i took it around the block and its fine...thanks for the help

 

what ecu, if you have a narrowband ecu and o2 sensor a air/fuel gauge will not read accurate at all

??? Narrowband ecu?? You mean if you have a narrowband o2 sensor and you hook your pretty little light display(air/fuel gauge) to it.. Yes, it will show narrowband signal which is useless for pretty much everything except telling the ecu where righer than stoic., leaner than stoic., and stoic. are.. Thats about it..

Like Mr_CRX said, its a pretty light show..

 

Check to make sure ur O2 sensor is working properly. Same thing happened to me.
