P0141 1996 Ranger 2.3L Automatic
Hi everyone,
I need your help once again for upcoming vehicle inspection. My 1996 Ranger runs ok but my check engine has come on. Using a scanner tool , indicates my cat monitor wont go to ready state and my error code is P0141. According to my research it indicates one of my 02 sensors. Does anyone know how to determine if its the one before or after the cat converter? About 6 months ago I had an exhaust leak repaired around my converter so I know I cant return it under warranty . If its the rear sensor , It looks fairly easy to replace but the front sensor looks a bit cramped. Any help would be greatly appreciated ! And thanks for reading.

DTC P0141 = HO2S HTR-12
That code implicates the O2 sensor downstream (after) the cat.
If there are two cats, then it would be the passenger side downstream 02 sensor.
Be sure to check the wiring and connection while you are under there. And check any related fuses.

I have a 98 f250 with P0141 code. I believe its the one downstream but how do I know if its the drivers side or passenger side? The reader didn't specify. It just says Sensor Heater Circuit.

The code indicates either '1' or '2', with the former being on the right side bank looking from the flywheel forward. Number 2 would be the left bank. The second digit says up stream or down stream sensor. 11 would be right/passenger upstream. 21 would be drivers/left upstream.
