SOURCE: how do you change sensors 02 and where are they

jack up the front of the car both sides using jack stands to support vehicle on frame rails. then locate sensors usually either on the exhaust manifolds or just below on the pipe coming out of the engine exhaust manifold, unplug wire from sensor and use the appropriate size box end wrench to remove sensor occasionally a map gas propane torch must be used to heat the old sensor up for 3-5 minute before it can be removed, if the plug is to big to fit through the box end side of wrench cut the wires to slide wrench over sensor

SOURCE: Can I get a copy of the procedure to change the 02

You don't need a copy of anything

All O2 Sensors are in both ends of the
exhaust converters on lincolns

All you need is a 22mm or 7/8" wrench

You will be changing only the front (2) sensors,
the ones closest to the engine at 100,000 miles
or when they fail

Ideally the check light or wrench etc & codes
don't always mean to change something

Assuming you won't know or have what is necessary
to test them, just change the front 2

Get the OEM NGK or Bosch at NAPA
Once you pull the sensor ,you will see the brand on it
The new wires may be 5" longer,just coil & wire tie

I used an old scan tool with a scope on mine, as a VOM
Meter didn't give you switching time & the scope really
was a nice test. You will notice an instant pedal response
with new sensors,I did with the Lincoln LS

Check that the rear monitor O2 sensors are tight
They loosen from the heat or were never tight from
the assy line

What would make a 96 Toyota camery cut off when its driven a while


O2 won't stop the car, only make it run rich. Likely a bad ground on the module or a bad connection on a plug. Many modules ground between the case and a metal mount. Otherwise buy some electronics cleaner for the terminals. Could the the mod, but normally they are reliable.

Code p0161 p0141 change the 02 sensor but still th light comes on.


Not likely both sensors fail same time look for a fuse or relay that has failed!

Reset codes and see if error returns if so and fuse is good check relay circuit.

Hope this helps?

My 2003 Lincoln Aviator emissions light is on and I failed inspection because of it. How can I pass inspection and fix this emissions problem? The inspection code given to me was PO420???


po420 is catalyst system efficiency below threshold. meaning is--- could be down stream 02 sensors or a bad convertor. try buy replacing down stream sensors, hopefully this may help. ( down stream 02 sensors are between convertor and tailpipe). have a good day !!

Where is the oxygen sensor located on a lincoln town car 96


My 96 has 4 cat converters, 2 (upstream and down stream) on each side. There are 2 oxygen sensors on each side, before upstream converter and after upstream converter. But make sure they are bad before you replace them (4 of them will cost you about $200), and my 1996 with 175K has 3 original still running. Other sensors (air flow, coolant temp) might be the problem as well.

I have a 1998 ford windstar and i need upstream & downstream 02 sensor but i dont know if i need 1 or 2 upstream sensors.


assueming it has the v-6 in it look at the exhaust pipe comming off the side of the engine there will be two up stream 02 sensors which are heated and one downstream past catalitic conveter. If may have the second style with the Y cross over with 1 upstream before the cat and one after. The difference between the 0-2 sensors is the upstrean are heated so it goes into closed loop faster. I find that on most of these the up stream 02 sensor heaters have failed. You can go to a Autozone and they can pull the codes for you and tell you which side it is that needs to be replaced. However 02 sensors get old after time and they start shifting slowly, if it shifts slowly then it's called a lazy 02 sensor. And will send a code to the computer, if you get the trouble code of the 02 sensor heater is bad you will have to change it, I recommend Replacing both. The reason is if one is going bad the other will soon follow. You can buy a socket wrench For the 02 sensors for 12 dollars makes it real easy to replace the 02 sensors when they are COLD. Hope this helps and thanks for using fix-ya.

The 2 02 sensors up stream went out so i changed them, car starts up fine then dies do i need to change the 2 down stream sensors two.


This may be another problem, a bad O2 sensors wouldn't normally cause you car to cut off. Don't guess with this vehicle have it put on a computer, I would recommend an Auto Zone store they will check for free. I would be more than glad to help you out when you get it check first to find code.Good luck and thanks for using FIX YA
