Ok, while installing the a Mopar SRT-4 A/F ratio gauge, Mopar oil pressure gauge and Mopar BOV (blue plate) conversion I got a check engine light. The car started throwing codes. It turns out that I needed a new O2 sensor. Does this sound right??? Which upgrade would have caused the O2 sensor to go bad or appear not functional?

 

none of those would do anything to the o2 sensor. why do you think you need a new o2 sensor? what code was thrown? what other mods are on the car?

 

Doesn't make much sense to me.....

 

Stage 1 with a CAI. Those are the only mods and everything was fine until the installation of the parts named.

 

what are the codes

 

P0133 & PO131

 

Just found out.....it is the A/F gauge and evidently it cannot be set up with the stock O2 sensor. You have to get an aftermarket O2 sensor. Doesn't make much sense but oh well. There is another 140 bucks down the drain. Oh yeah, it is reading rich.

 

i've never heard that one before...it's the mopar a/f guage so why wouldn't it be able to use the stock o2 sensor? that's weird....

 

if ur o2 sensors throw the check engine light it will run rich... because it wont know where lean or rich is... so its safier to run rich than lean.....

 

According to Modern Performance; The Mopar A/F gauge is wideband so you need a wideband O2 sensor.
