Does anyone know any o2 sensor (backs) that will keep me from paying the exorbitant AM parts desk price ? I have found fronts but not backs, any help would be most helpful to many of us.

2007 v8v manual

 

What model and year? Direct compatibility will likely be found in Volvo sensors, but if you're real savvy in the mechanical department you can just use universal sensors. AM uses a 4 wire heated sensor just like most manufacturers, just make sure you marry the correct wires from the harness to the new sensor. Usually universal sensors come with a wiring diagram to fit different applications but since it's for AM I'd call the O2 sensor manufacturer and make sure you've got the right hook up order.

 

I had bad luck splicing supposedly compatible generic O2 sensors in for the back sensors on my 2007 V8V. Kept throwing catalyst efficiency codes. Replaced them with the pricey AM parts and no trouble since.

 

i recently went through this

my pre-cat o2 sensor was going - so i decided to research this and change them all out

here is what i found:

am oem part: 6g339g444aa = ntk oza488-am1 (rear sensor)
am oem part: 6g339f472aa = ntk oza381-am1 (front sensor)

i have a 2010 amv8 roadster - the above sensors worked and i was able to pass ca smog

pm me for tips on where to buy and how to clear obd II monitors

The 4.3L cars have the O2 sensors in different locations than the 4.7L cars. I couldn't find any aftermarket sensor (including those from NTK) that had long enough leads to reach the back sensor location without splicing. And the splicing caused problems.

 

Actually the 4.3L and 4.7L(until 2010) have them in the same place..its the 2011 onwards that have them in a different place

 

Thanks for the correction!

 

Irish,

Are the 4.3L and 4.7L (until 2010) use the same o2 sensor?? I need to replace my upstream, thanks.

 

Same thing.. If it's because of a lazy sensor, good insurance is to also replace the PCV to avoid sucking in any excessive oil that will coat the sensor over time

 

oil catch can helps with that

 

Hehe..I'm trying to up sell for you without advertising ;-)

 

I am getting these every since I started to put 91 Shell

P0133
O2 Circuit Slow Response (Bank 1, Sensor 1)

P0153
O2 Circuit Slow Response (Bank 2, Sensor 1)

Never at the same time, I get one, reset it and about 2 weeks later I get the other... so far I reset them about twice each

 

You guys are great, that is one sure thing... I will get an oil catch can and other stuff but just got the car and trying to sort a few thing out first

 

Bumping this because I'm dealing with the same issue. Did the oil catch can sort it out?

 

o2 sensors fix the issues, I send you a PM
