Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hello,I will be glad to try and assist you with this,Welcome to Just Answer.
This ounds like you have a wheel sped sensor failing,sending the wrong signal to the abs computer,this will turn on these lamps and activate the traction control,what needs to be done from here is to observe each wheel speed sensor data with a scan tool to determine which one is at fault,this can be done by any shop.
It does sound like you have a tire pressure sensor at fault since the pressure is o.k.
A new one will have to be installed and has to be done by a tire shop as it is located inside the tire.
There isnt a way to deactivate the tire pressure system on this vehicle as it is considered a safety feature.
I dont have an exact part number for this sensor as ir depends on the Mhz signal but the labor charge to install this is .8 of an hour.
From Auto Zone the sensor part number is XXXXX sensors houlodnt be to expensive I would say around $30 each and possibly less in some parts stores,you can buy them from a dealer/tire shop/or almost any parts stores.
I hope this helped,Thanks Pete!
The part number is XXXXX the tire pressure sensor,this is an autozone part number but if you go to a parts store they should be able to cross this number in most cases.
Your vehicle has four sensors,one on each wheel hub assembly,in the rear this sensor can be replaced without having to replace the hub but it does require a special tool to install the new sensor,this is a GM service tool that Cadillac dealers will have.
For the front you would have to replace the entire wheel hub assembly to get a new sensor,I dont have the costs on these but rear sensors can cost around $30 to $75 each as the hubs can run $150 to $300 each depending on where they are purchased and whether they are factory or after market.
You will need a scan tool to watch each speed sensors signal while coming to a stop or driving to find the one that is reading incorrectly compared to the rest.
