oxygen sensor help needed,

[madbrian]

i have checked my front o2 sensors and have discovered they are both NTK however they have different numbers embossed on them.
from memory when they were bought the plugs are both correct however 1 of them had a large 3" grommet on the wiring obviously from a different model car.

will this cause the car to miss, buck etc under 3,000 miles?

 

[madbrian]

any one know?

 

[Madduc]

I'd call Tator and get the correct ones for you car.

 

[99 R/T 10]

Agreed, Call Chuck at 914-763-3136

 

[bluesrt]

if they are not oem parts(mopar) and not correct for that year,anything is possible,get that corrected first before you even try to start monkeying with anything else! period! end of discussion! get to getting!

What year car is it?92-95 uses a 56028301. 96-98 uses a 56041212. 99-02 uses a 56041212AE.All of these are upstream sensors.

 

[madbrian]

it is a 99 gts.

the number on one of them is 56041212

there are no letters after it, do you know if the letters make a difference ?

 

[Tom Sessions]

The 56041212 does not change to the 56041212AE in the Chrysler parts book, I would put the sensor in your car.Not sure what the difference is.
