1992 Cadillac Sedan Deville Oxygen Sensors

Showing 8 out of 8 Posts
Question From kmfmgk on 1992 Cadillac Sedan Deville Oxygen Sensors

The check engine light comes on and car runs rough as if on 6 or 7 cylinders. I had the plugs replaced. They were original plugs with 154,000 miles on them. It ran pretty good for about a week, good gas mileage and then it did it again. I check the fault codes and have E-13 and E-44 which means oxygen sensors. Where will these be located on my vehicle and are they hard for a novice to replace. Any and all advice will be appreciated.

Response From Discretesignals Top Rated Answer

E-13 basically means the O2 sensor isn't active. Could be from a wiring issue, the sensor has oil leaking all over it, the sensor got contaminated by something, or the sensor has failed.

Your Caddy only has one O2 sensor. It should be located in the exhaust manifold near the engine firewall. You might need a special O2 sensor socket to get it out if you can't get a 7/8 inch wrench on it.

If the O2 sensor is contaminated because the engine is burning oil or coolant or it is being leaked all over, you'll wreck the new sensor if you don't correct those issues.

E-44 is o2 lean. Could be either because the engine is actually leaned out, you got a misfire going on, you have an exhaust leak before or around the sensor, the sensor is stuck lean internally, the crkt is shorted to ground, or misfiring cylinders.

Being the age of the vehicle, if the sensor is original and is not contaminated by something, it probably wouldn't hurt to replace the sensor and check its voltage output. You can do that with a volt meter back probing the O2 sensor connector. It should fluctate between 0 and 1 volt DC. Your sensor does not have a heater, so you will need to heat up the sensor by raising the engine rpm or driving the vehicle at cruising speeds.

I recommend NTK, Denso, or a Delco sensors. Don't install a Bosch or universal one.

Response From kmfmgk

Thanks, Discretesignals. A lot of good info. I will follow up on it. Jim

Response From kmfmgk

I want to thank both Hammer Time and Discretesignals for all their help and advice on the oxygen sensor problem. I have located it and it is completely dry and does not appear to be contaminated in anyway. I am currently looking for a vacuum leak. I have no leaks anywhere that I can find. One of you mentioned burning oil or coolant. I can smell coolant after I drive the car for a short time, but it goes away quickly. Does this give you any idea of what to look for if it is a coolant problem that is affecting the oxygen sensor?

Response From Hammer Time

You can't see contamination in an 0/2 sensor. The sensor is internal.

Response From Tom Greenleaf

Quote now important noted ">> I can smell coolant after I drive the car for a short time, but it goes away quickly."
Are you losing coolant? Not from the recovery bottle I mean any air at the radiator? If that's really burning coolant that's first thing to chase down IMO or what's the point in continually trashing sensors?
Pressure checks, look for one or more spark plugs even now newer that are different up to a compression check and of course anything visual seen,

Response From Hammer Time

First understand one thing. There is NO code that means any component is bad. The component referred to in a code is not necessarily the cause of the code, especially when you are talking about 0/2 sensors.

The E-13 is 0/2 not ready and the E-44 is a lean code. Something as simple as a vacuum leak can do that.


Code E44 will set when:

  1. There is an oxygen sensor circuit fault giving a false lean indication. OR
  2. When the air fuel ratio is actually lean due to a vacuum leak or fuel control system fault.



Possible causes of code E13 are:
  1. An open in CKT 412 or 413.
  2. A short to voltage on CKT 412 or 413.
  3. An oxygen sensor that cannot respond.

2005 Grand Am missing and gas hog issues

Question From Trvsh5 on 2005 Grand Am missing and gas hog issues

We have tried changing the plugs, wires, oxygen sensor, and fuel fliter. Also cleaned the mass airflow sensor. Over the last year it keeps getting worse, the only code it throws is the oxygen sensor even after we changed it. When starting to take off and going under 40mph is runs real rough like misfires. Also when sitting idle for awhile like to warm up, sometimes when I get in the car it smells like gas. The fuel millage has went from 320 to 240 in the last year. I have been told it could be the fuel regulator or the cadillac converter but most mechanics say there is nothing wrong with it...boy are they wrong. It runs so rough its scares me to drive it. Please help before it nickles and dimes me to death playing the guessing game.

Response From Hammer Time

What are the exact code numbers being set?
What engine does it have?

Response From Trvsh5

Im sorry I dont remember the code I can tell you tomorrow after we read it again bc the light came back on tonight. It has the V6 Engine, Im reading online now and it says maybe the timing is off, would that make it eat gas too?

Response From Hammer Time

I need the code numbers

Response From Trvsh5

Ok I know it was the front oxygen sensor but I dont know if it says anything else. I will get the exact code tomorrow morning when I get to work.
Thank you for your help

Response From Hammer Time

There are no less that 20 different codes related to oxygen sensors and they all mean something different.

Response From Trvsh5 Top Rated Answer

Ok it was not the oxygen sensor code this time it was a random misfire code P300. Now were really lost :(

Response From bambam70

does that have the quad 4 engine in it ? either way 4 or six, have you done a power balance on it ? using a test light grounded push it into the wire plugs where they go on the coilpack. make sure all cylinders are firing. sounds like your misfire may be an ignition prob. if you ground one of them and it does not react, thats your prob, that will also make it run rich, causing the o2 sensor to set codes. may not be your wires, may be a prob with your coil paks.

Response From Sidom

You don't want to probe the boot like that with a test light. It puts a hole in the insulate boot and will let the wire arch. Basically it ruins the wires, we're talking high voltage here and don't want any type of leak in the insulated boots or wires.

That's an old school test that actually works pretty good. If you want to do it without ruining the wire, get some 2" sections of vacuum line, super glue a spark plug tip into one end for the wire so the wire will snap on to it and put it in line between the wire & coil pack and then fire up the engine. Now you just need to touch the piece of vacuum line with the test light & it will ground the cyl without ruining the wire........

Response From Trvsh5

We have not done that yet, they have tested the wires and plugs but not to the coil. It does have the V6 engine. I think you might me right bc it has issues starting at times it just did it again tonight where it didnt want to start then i tried again and it started and shut off then on the third try after it started i hit the gas to keep it running, after that it ran fine on the way home. I think im going to try some GM fuel injection cleaner and have the coils tested. Thanks for all your help

Response From Hammer Time

How old are the plugs and wires?
I suspect it will set the O/2 codes again eventually and that will help identify the problem.

Response From Trvsh5

The wires are less than a year old and the plugs are 3 days old. I got good plugs and wires not the cheap ones. Ya im thinking the same thing, just hoping its not the timing chain and it leaves me standed one day lol
