I took my Town&Country in to a local shop to have them scan the codes as my engine light is always on. I received 2 codes: P0140 1/2 O2 SENSOR and P0141 1/2 O2 SENSOR. Would the 2 O2 SENSORs be caused by the actual oxygen sensors ? or would the caddy itself needed to be replaced ? Thanks.

Sensor is behind engine and between engine and firewall, the spring on electrical cable should identify it. One recommend you go to you tube for removal and installation.

O2 sensor, sensor 2 bank 1.

Have you had the vehicle scanned for codes?

Once you have the codes, you can look them up on the web. Just do a search ' 94 Lincoln town car code.....' Just plug in the code(s) number.

Code 135 is for a problem with the heater circuit in the O2 sensor for bank one sensor one. That is the sensor for bank one in front of the catalytic converter.
The sensor would need to be tested to see if the sensor has failed or if the problem is in the wiring.

Have Autozone do a free scan for your codes. Their scanner can also reset your light. FREE

The check engine light.

This light will illuminate to warn you that there is a problem with a computer controlled device, a sensor that feeds data to the computer, or a fault in a system. The vehicle may act and drive normally. Some common causes for this are EGR valves, loose gas caps, and EVAP leaks.

To find out why the light is one you will need to have the computer scanned for codes with a scan tool. Your local parts store may be able to do this for you or for a diagnostic fee have a shop diagnose the problem. Once the problem is repaired the codes can be cleared and the light will turn off.

Go to your local auto parts dealer. Most of them will read your codes and give you the meaning of them. Auto Zone is one that always provides this service for free and lots of others do too.

there are no codes that say replace O2 sensors,or remove converter,Thats just somebody's guessing,When it says O2 sensor that tells the mechanic to look for trouble in that area,wiring or faulty readings,And there are four O2 sensors.

more electronics means more suceptible problems if this is a safety or emission prolem find the computer codes it will tell you the problem,the check engine light will flash a series of codes if it is a problem geting it to pass this will help if it is not a problem dont worry yourself let the light come on some cars allways have this problem if the car runs well take out the bulb if the light bothers you i suspect a dirty oxygen sensor malfunction

Dont be worried at all. The battery temp sensor isnt very important, most cars dont even have them. The only thing is you will have that light on. Good luck!!
