Hey,

I just installed my Autometer Nexus Wideband and spoke with a tech at autometer to use the same O2 sensor on the driver side exhaust manifold so I crimped them as autometer stated to save a little work as far as installing the bosch sensor.

Everything seems to work other than my service engine soon light came up after install and my reading stays at 14.5. Is the reading suppose to change during acceleration or anything or is the reading suppose to be constant meaning the car is receiving 14.5 air/ fuel mixture during all rpm?

 

Something is wrong there. No car has a constant 14.5 AFR.

I'm guessing their instructions told you to use the stock sensor and just tap wires to it?

I'd personally only use a new sensor and not tap into the sensor the engine is using. The idea of having the gauge over just having the stock ECU verify things, is so that you can actually verify it. If you're using the stock sensor and it's bad for some reason there is no way to verify it without that additional sensor.

Also never crimp. Crimp is for temporary connections and shady install shops. Solder and heat shrink all wires.

What it sounds like though is that you tapped into the narrowband sensor, or the wrong wires on the wideband sensor.

 

Thanks for the reply.

Well yeah, I ccan say I craped it myself. Ran one wire incorrectly.

Thanks though.
