Yesterday I logged all day and kept getting .0xxxxx voltage. Today I unplugged it and replugged it back in. This is what it’s doing now. Normal?

 

Can anyone confirm that this is “normal” front o2 behavior?rear o2 column on the right of it and seems to not be moving but I’m unsure if that’s normal either.

 

The front o2 seems to be functional.
The rear o2 looks like it might be disabled in your tune and feeding a set value into the ECU.

 

it’s a oem rom. Only immobilizer disabled and verified. Cat monitor does set normally. My main issue I’m trying to fix is the P0300 and making sure my “lazy” front O2 sensor is fluctuating correctly.

 

Denso 234-4741 is OEM swap far as I can figure out, it's 85$ in Canada so what, like 6 bux for you guys? Seems like a cheap choice if your sensor been in there for any amount of time?

 

Lolol the conversion rate isn’t that great. But yea I’ve never changed it and the car has 113k on it. I’ve owned it since 95k.

 

Now I'm itching to know how cheap it is!?!
Blah blah mileage, fresh sensor and all that jazz.

 

local auto parts store for front o2 sensor from denso is $83 +tax or so USD.

 

Looks like its about $50-60 on amazon and rockauto

 

I ordered from amazon the other day, returning it. Box was mangled up, and it didn’t include the anti seize. From researching on other forums, all authentic sensors are supposed to come in plastic bag and include anti seize which to me makes me think it may be a fake.
