I have a 95 F150 with a 351 eng. I can only find 1 0xygen sensor
which is located on pass side where drivers side exhaust meets pass side. I was told there are 2 O2 sensors but can only find one. Does anyone know if there is another sensor or if this truck only has one.

 

I have a 92 with a 351 and I was also told that there were 2 sensors. Bought 2 used 1. I searched everywhere and there is only one on mine too.

 

Thanks for your reply. I did some searching since my original posting and found out that the MA and CA models arer required to have 2 sensors and the rest of us only have one.

 

Rodger,

I suspect that the trucks with two sensors are the '96s, as this was when OBDII came into the picture.

I have a '95 302 that is mass air and it only has a single sensor as well.


Looks like there are several of us pre-97 owners in Va Beach and the surrounding area now.

 

Your '95 has the single O2 up by the Precat just like my '88...that's it!

My '01 Z71 has 4!
