Primary and secondary 02 pin confirmation
So i have swapped out my cat a million times. This is the first time getting a slow response code for primary sensor when stock.
I figured I had finally killed on O2 sensor.( at 34k?) Ordered a new primary sensor from fcp. It does not fit the primary sensor connector but the secondary. So, me thinks I might have swapped sensors somewhere in this last revision. ( 1.5 hour revert back to stock) I even have my label 1 and 2, but they are not in the right spot, but its been so long cant recall if that was position on body or respective O2 location. Can someone confirm the number of pins on the primary and the number of pins on the secondary O2. Primary 4 or 5 pins? Secondary 4 or 5 pins? Right now I have a 4 pin in the primary and a 5 pin in the secondary. I know stupid me, but want to confirm before I un button everything. Hopefully that is the fix and I can return the sensor. Thanks in advance. |

I'd go by the part number on the sensor - 11787596908 is the upstream sensor, 11787645875 is the downstream sensor. Normal convention would dictate a 4-wire sensor is a narrow-band one and 5-wire sensor is a wide-band one. The upstream sensor should be a wide-band one, if they are both not narrow-band sensors.
