Traction light is on with abs-loss of power - 1997 Pontiac Bonneville

The code P1934 indacates a problem with the VSS input. it does not match OSS signal (out put speed sensor) trans.

What it looks like: The traction control warning light typically takes the form of the acronym "TC." Sometimes this light is a small illuminated picture of a car losing control What it looks like: The traction control warning light typically takes the form of the acronym "TC." Sometimes this light is a small illuminated picture of a car losing control. How this system works: Traction control uses wheel speed sensors to detect when one or more of the car's wheels lose grip and traction. When the system registers a loss of traction in one or more of the wheels, a computer will limit power to the wheels that are still in solid contact with the road to prevent a skid. Common reasons for this to happen:

• ABS is malfunctioning: Traction control and ABS (anti-lock braking system) often share the same control module and internal self-diagnostics system. As a result, sometimes an issue in the ABS can trigger the traction control light. If this is the case, then both the ABS and Traction Control lights will be on.
• Broken wheel speed sensors: Wheel speed sensors are usually in the wheel bearing assembly, and determine the rate at which each wheel is moving. The sensors relay that information to the traction control module, which determines whether or not power needs to be shifted. Wheel speed sensors can get dirty or damaged and stop working, which prohibits the traction control module from knowing when to enable the system.Traction control module is faulty: The traction control module - which, again, is often shared with the ABS - can malfunction and break altogether, causing the system to stop working. What to expect: A top-rated mobile mechanic will come to your home or office to determine the source and cause of the traction control issue, and will then provide a detailed inspection report that includes the scope and cost of the necessary repairs. How important is this service? It's important to have the traction control issue investigated as soon as possible, as adverse driving conditions can arise at any time. While your car is unlikely to incur further damage from a faulty traction control system, it won't be safe to drive in rain, snow, sleet, or other inclement weather, or even possibly through pools of water on the road. Furthermore, the issue that is causing the traction control light to illuminate could also be impacting the ABS.

With some makes and models this is normal. The PCM will reduce engine power when the traction control senses wheel slip as a safety precaution until traction is restored

Traction control helps by controlling the engine power to the drive wheels to prevent wheel spin. When traction control is OFF then you can apply all power to the drive wheels and it could cause loss of control and or wheel spin.

You will need scanned the ABS Module to know exacvtly what fault code is stored there; with this copde number we could send you othyer details to solve it. Generally is the Speed Wheel sensor go to bad or loss connections.

Keep in touch.

If the the abs module fails you still have breaks BUT if you need to apply the breaks to the floor the abs will not work which could allow you to go into a slide because of loss of traction. the abs system pumps the breaks to prevent your tires from locking up

Had the same problem with my 2002 Lincoln LS, it was a bad wheel speed sensor. The right front wheel bearing had some play in it, so I had the hub assembly replaced. The hub assembly comes with a new wheel speed sensor attached. After I replaced the hub assmbly with sensor, the ABS and Traction Control lights went off. No problem since!

ABS stands for anti lock brake system.
TCS stands for traction control system.

I recommend having your abs system diagnosed for faulty sensors, control module, etc. With the abs light on the traction control system is designed to disable because it utilizes the abs system to automatically help control your vehicle in loss of traction situations.

traction control has nothing to do with the egr valve.

likely you have a bad wheel speed sensor somewhere.

Have the ABS scanned with a scan tool at your dealer
perhaps.

Hope this helps.

Hi when the ABS and TRACTION light come on there is a FAULT CODE STORED in the EBCM
I need the code before I can help you
