1991 ford thunderbird

The O2 sensor is in front of the catalytic converter in the exhaust pipe.
You should be able to use a wrench to loosen the sensor and remove it.

Will not accelerate past 25 mph

If O2 sensor the car will jump while accelerating. Could be that it is the catalytic convertor. Could be an issue with fuel filter, though unlikely. If its jumpy at 20-25 then I would agree with you.

My problem with FixYa is the idiotic returns on search. For insance, My search is 1997 Ford Thunderbird engine code 141. Fixya returns a reply with a ton of non-related, non-authorative replies. How...

DTC P0141 - O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)
This code means that the heated circuit in the oxygen sensor on bank 1 decreases time needed to enter closed loop. As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it. The ECM tracks how long it takes for the oxygen sensor to begin switching. It the ECM determines (based on coolant temp) that too much time elapsed before the oxygen sensor began operating properly, it will set P0141. See also: P0135 (Bank 1, Sensor 1).

You will likely notice poor fuel economy the illumination of the Check Engine Light.

Causes: A code P0141 may mean that one or more of the following has happened:
open or short to ground in the wiring harness
O2 heater circuit wiring high resistance
O2 heater element resistance is high
Internal short or open in the heater element

Note: Typically a failed catalytic converter does not cause this code. You're more likely to see a P0420 code for a failed converter.

Possible Solutions:
Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)
Repair short or open or high resistance in wiring harness or harness connectors

Here is the daignostic procedure for troubleshooting DTC P0141 (click over each image for zoom)...


Hope this helps to solve it.

Need to replace o2 sensors on a 1997 thunderbird

you will need to crawl under the car and look at the mufflers where they come out of the motor and behind the catalytic converter. you will probably have one before and after the catalytic converter on both pipes. You will have to count the wires once you find them. They will be screwed directly into the exhaust pipe.

I have a 1997 thunderbird lx limited exdition with the 4.6 liter. A code for catyletic converter popped up. There is no egg smell. could this be bad o2 sensor or something else? This car has 173,000 miles...

If you have never replaced your oxygen sensors then that is probably the cause, you can usually expect 50-100K miles out of an O2 sensor. If you have the money replace all of your O2 sensors at the same time, it should also help with your mileage and performance a little.
