SOURCE: O2 Sensor on a 1996 Cadillac Eldorado

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!

SOURCE: Overheating

Many items need assessment. First what is THE COOLANT LEVEL enine running from cold start. IF LOW . Is there a coolant leak and where ? Lets say all of the previous check OK. ARE THE COOLING FANS OPERATING ? . They are , GREAT. Is it possible the cooling system ( i.e. radiator ) is clogged internally, or blocked exterior cooling fins of the radiator restricting cooling air. Hope this helps.

SOURCE: camshaft position sensor

The camshaft position sensor is on the rear cylinder head on the left end (the serpentine belt end of the engine - passenger side). It is a son-of-a gun to get at. When it is bad or the connector is intermittant or bad, the symptom will be irregular idle from 500 to 750 RPM or so.

Turn Signal/ High Beam Lights/ Driver Window/ Horn suddenly not working! Help!


These are just ideas, but In my simple attempt....start with checking, or have someone check every fuse in the fuse box. Another thought is that the turn signal indicator arm that controls blinkers, high beams has finally gave out. And when it did, it might have shorted out the horn. Being a 1993, it has probably seen some usage. Does the cigarette lighter work?? Also check the fuse in the fuse box that controls the horn, because in some of my experiences, the cigarette lighter and the horn are sometimes on the same fuse.

1976 eldorado horn does not work


Probably your horn cam in column, this can be checked and diagnoist easily, I believe it is a dark green wire that comes down the steering col. wire harness. If you grd. this wire horn should blow, how it works is when you push on the horn pad it grounds the circuit to relay and relay switches and puts power to horn to blow.Also make sure your steering column is grounded, which is usually through the rag joint to steering shaft

I am trying to fix the horn on my 95 Eldorado but none of the fuses are labeled as the horn so I don't even know where to start. Can anyone point me in the right direction?


I suggest check the LH Maxi Fuses (Seats/Horn), also can find it in your 1995 Cadillac Eldorado - Owners Manual (page 325).

The fuse block is located in the glove box behind an access panel on Eldorado and Seville. There are 2 fuse blocks on 1992-98 Eldorado and Seville, one located in the left-hand side of the engine compartment, on the wheelwell and the other is located on the side of the trunk. To determine if a fuse is blown, remove it from the fuse block and examine the fuse element for a break. If the element is broken, replace the fuse with one of equal current rating.

You will need to test for power on 2 terminals, ground when the horn pad is pushed and if you jumper power to the horn wire the horn should play. What doesn't work will determine what needs to be fixed. There are bulletins that deal with the air bag in the steering wheel as being a problem so if you don't get a ground when the horn pad is pushed then I would suggest taking it to the shop and have someone repair that part of it because serious injury can result if propper steps aren't taken to disable the SIR system before disassembly. Also some special tools might be needed depending upon how deep into the column you need to go.

Horn not work on subaru forester


Their is no connection between your antilock brake system [abs] and your horn. Most of the time when the abs light goes on the problem is in the sensor and not the abs. Regarding the horn, I would check the fuse that controls the horn. look in your owner manual for the fuse diagram and replace that fuse with a new one the same amperage.
