Look if the engine is doing what you say then it is overheating and there is no problem with the sensor, remember the sensor only tells what is going on, it does not cause anything like overheating. Have you bled the system of air, there is a factory procedure to do this.

The map sensor shouldn't cost more than 50 bucks or so. It is very easy to change, and can be done w/ simple tools. It mounts to the intake manifold. There is a wire connector that plugs into it. Just remove the two mounting bolts, and the connector, and it will pop right off. This is not a tough repair, so it can be done in about 10 minutes at most. This should save a trip to the repair shop!

Hello mrsalbert, my name is JShreader. Thank you for choosing fixya.com

Depending on which oxygen sensor you are looking for...there are several of them throughout the Exhaust System. I will start out by giving you a brief description of what and oxygen sensor is, and they're general purpose.

DESCRIPTION
Four Heated Oxygen Sensors (HO2S) are mounted in the exhaust system where they monitor the oxygen content in the exhaust stream. There is an oxygen sensor mounted in each exhaust manifold and one on each end of the catalytic converter. the oxygen sensor located in the front exhaust manifold is the Bank 2 Sensor 1 (Front) sensor. The oxygen sensor located in the rear exhaust manifold is the Bank 1 Sensor 1 (Rear) sensor. The oxygen sensor located in the Y-pipe ahead of the catalytic converter is the Bank 1 Sensor 2 (Pre-converter) sensor. The oxygen sensor located in the catalytic converter outlet is the Bank 1 Sensor 3 (Post-converter) sensor.

OPERATION
An oxygen sensor acts like a battery because it creates its own signal voltage once it reaches operating temperature. This voltage is produced when the oxygen content in the exhaust stream is different than the oxygen content in the atmosphere. A lean condition (high oxygen content in exhaust) will produce a low voltage (near 0 volts) and a rich condition (low oxygen content in exhaust) will produce a high voltage (near one volt). The PCM provides a reference signal voltage (0.45 volt) and a ground to the sensor. The PCM reference voltage is necessary because the oxygen sensors do not provide their own voltage until they reach operating temperature.

HEATING ELEMENT
the oxygen sensors also incorporate a heating element inside of the sensor housing. This heating element is energized with the ignition On and allows the sensors to reach operating temperatures quickly. The PCM can then use oxygen sensor information sooner after engine start-up.

PCM INPUTS
The PCM uses oxygen sensor information during Closed Loop operation to constantly adjust fuel control to reduce exhaust emissions. Because the oxygen sensors provide information sooner after engine start-up, exhaust emissions are reduced. Faulty oxygen sensors will cause various driveability conditions and will set a DTC.

That being said...I uploaded a .pdf for you of pictures showing the locations of ALL the oxygen Sensors on your Vehicle. You can download it by clicking HERE.

I hope this helps you. If you have any more questions or need any more diagrams, please don't hesitate to ask...Thanks again, JShreader!

Have a 1988 Cadillac DeVille 4.5L TBI. It's stalling and hesitating when put in gear. Changed plugs,cap,rotor, and wires. still has an issue. service light comes on and goes off and comes on again....


Changing the fuel filter isn't a bad idea prior to getting into the O2 sensor. You may want to consider replacing the TPS (throttle position sensor). Do an on board diagnostic test to identify the areas of concern. Most likely you'll get error codes for both the MAF sensor and the TPS.

How do you change the o2 sensor on a 1994 cadillac sedan deville?


U must get under the car, the sensors (2 of them) are in the exhaust pipes, it takes a special 7/8" O2 socket to remove it or if u can get it in there an open end 7/8" wrench will work. Remember sensors should always be replaced in pairs.
