Question about Cadillac STS

ABS and Traction lights are on, Service Sytstem stability on dash displays

These lights were never on until I had a shop replace my o2 sensors. He asked if I had air ride and to turn it off but there is no off switch. He did the work, my engine light is off. I left happy until I noticed these yellow ABS and Traction control lights were on. I've had all four brakes done last month and new rear shocks put in same time. I called the shop who did the o2 sensores , he says my computer is old. Or may need a sensor over the phone and to disconnect my battery then reconnect it. If it didn't go away he said he'd look at it. I did what he said but instead of saying bring it in, he told me the computer is either tired or I need a sensor or two replaced.. Is this a coincidence?? or does he know he did something and doesn't want to have to pay for it??Anyway can any one help me with this I usually do my own work but I had him do the work because the O2 sensor's needed re threading on the pipe. Any input is appreciated.. I'm sick of my dash board telling me to do.. lol.. in short he fixed one problem and introduced more!! why are my lights on?? I

I don't know how he fixed damaged O2 Threads in exhaust pipe

He must be a magician

I would just go back to doing your own work or try another shop

I never knew computers grow old,my dog grows old,not electronics
for the most part

No professional worth anything, would want you to clear all data,
as they would clear data that was needed to possibly resolve things
& you don't as a shop owner discuss things over the phone as the
customer gets confused

I would say you have a new problem with possibly a bad wheel speed sensors

The computer is tired or you need a sensor or two are not acceptable answers. Its possible he damaged something by lifting the car.
I would take it somewhere that can scan the computer for trouble codes and see what has failed. The computer stores codes when the warning lights are on. Once you know what the codes are you can figure out if it is something he may have done.

SOURCE: how do i replace a left front speed sensor on olds

Have you worked on your own vehicles,? The speed sensor is a 1 bolt 10 min job. The real question is that the problem? Who told you ,a professional who actually tested it. Why not have them finish the task and replace it

SOURCE: traction control indicator on, check engine light

u don't need an obd tool for a caddy. you can read/clear it yourself using the dash controls. the traction control light probably won't clear until you fix the problem. usually it's a wheel sensor which involves changing the wheel hub. not a big job. you need to find out which one is bad and the 'puter should tell you that. here is a website i found that will tell you how to read/clear the codes as well as what those codes mean. this should be helpful.

get a new mechanic, need to check for vac. leaks, poss needs tune up. alot O2 codes i have gotten have been created by vacuum leak or warn out plugs, rarely have i had to replace a O2 sensor.

SOURCE: I have an /05 Highlander.

The VSC has nothing to do with the O2 Sensor,TPS Sensor or EGR Valve.

I will not express what I'am thinking,but in reality,NO Diagnostic work was done
on your vehicle.

My advice,and I don't know why the pros aren't all over me yet,is never go to a dealer.
You and thousands of others on this site alone,are perfect examples of why you
go down the street, to a local repair shop that cares.
I bet if you checked your in & out milage, that they are the same. Never road
tested,nothing,just threw parts at it at your expense.
There are good techs at dealers,but no service Mgrs that care,it is all about
taking your money and selling services you don't need. On the 5th visit they will
make the drivability repair you went there for.

Common sense: asumming they pulled codes
you never have multiple sensor failures all at one time.

SOURCE: I have my check engine

bank 2 is the bank that doesn`t have cylinder #1 in it.sensor 2 is the sensor after the catalytic or at the rear of the catalytic converter.with mazda use a good quality sensor(preferedly factory) as if its poor quality sensor it will set a code and cause also usually have to cut and splice the wires to the original plug to use them.try buying one from a parts store that you don`t have to cut and splice that way it theres a problem with the sensor you can get it replaced easier.

Holden epica electronic stability program light appears on dash were a re the sensors and likely problems that would cause the dash light error code to comeon please

Traction control is with the wheel sensors. A bad sensor, bad bearing, or bad wiring. ABS is also controlled by these. Code readers don't read ABS and Traction control. Get the vehicle on a scanner....

Service stability system, abs light, traction control light

Since both of these systems rely on the wheel speed sensors, this is probably what needs to be replaced. If you don't have your own scanner or can't find a part store that can give you ABS codes, it would be worth it to pay a shop to give you the code so you can replace the correct sensor instead of guessing.

There's a little light that says "low trac" that goes on when i turn on my 1998 chevy cavalier.... what does it mean??

means the traction control module is bad. That light is suppose to come on when you lose traction to let you know the traction control is kicking in.

What does the low traffic light mean in a 1998 chevy cavalier?

If your ABS light is on as well, have a shop scan it (it requires a special scanner). If it's just your Trac light without ABS, it is most likely a sensor under the hood at fault. If you are getting a check engine light as well, get the codes read!
This happened to me without an ABS light and it was the upstream O2 sensor. The reason it throws the Trac light is because if any components that the traction control uses (ignition, fuel) are affected by a bad sensor, the PCM shuts down traction.
In fact, when I replaced the O2 sensor, a handful of other little issues resolved as well.
If you do have an ABS light on, it could very well be a wheel speed sensor.
