2005 Ford Focus - Traction light stays and car beings to hesitate
Recently my traction light has came on, and stayed on. It wasn't because of slippery surfaces, maybe just rain. Before the light comes on the rpms begin to bounce up and down, from 1500-2000 back down to 1000. It feels like the vehicle isn't getting fuel. Then the traction light will appear and the car begins to run alot better, but from time to time, the rpms will dip. It has happened to me three times in the past month, but it goes away after I shut the car off, and it happens again in a week. I`ve notice that it happens when the car is wet. I was washed my vehicle, and it happened asoon as I drove out of the carwash, and tonight, during a rain storm. Can anybody give me an answer? could it be a wheel sensor?

If someone didn't turn Traction Control off by means of a button, it is telling you Traction Control is OFF or malfunctioning. Instrument panels lights are supposed to illuminate as a lamp test for a couple of seconds each time you start the engine. If the Traction Control is not operational you should have it checked by a dealer, they are familiar with your car and have likely seen this before. Traction Control is an important safety feature that needs to work properly to help you avoid loss of control while driving in slippery road conditions.
Reduced power is a problem with electronic throttle contol . drive by wire . Do you know what this is ? Taking the vehicle an having it hooked up to diagnostic tool an checking for DTC'S - diagnostic trouble codes is always a first step when trying to find the root cause of any trouble light ! And not auto zone , pep boys , or advance auto parts . Thier diagnostic tool will not check codes in all system control modules .
1. to let you know that your Traction and Stability Control System is active. This means that your tires are slipping or your car is leaning and the ststem is actively taking corrective action. This should only cause the light to come on for a few seconds at a time.
2. To let you know that the Traction and Stability Control System is disabled. It may be because the button has been pushed to turn it off or it may be due to a malfunction in the system. Thjis will cause the light to come on and stay on. If it is staying on and it is not because you have turned it off, then the system will have to be diagnosed to find out what the malfunction is that has caused it.
i have had this problem since about 6 months after i bought my 2001 impala. the problem is in the hubs. the wireing that runs throw them rubs together and eventually shorts the traction and abs. easy solution to fix it though. get into the hubs and wrap the wires. otherwise take the car in and explain the problem to them and exactly what you need done. 9-10 times they won't fix the problem unless you tell them what you want done. it is really simple and going to the dealer should only cost you about 100 to fix.
Risk for slippery conditions If the warning light comes on and stays on, this indicates that traction with the road surface is reduced. Drive with caution.
If this light flashes, it indicates that the DSTC system is working to restore traction to one or more of the wheels.
Reduced Stability Control If the green indicator light in the DSTC button goes out, DSTC has reduced effect because the system had been switched off with the button in the center console. The text DSTC SPIN CONTROL OFF will be displayed in the text window.
The traction control system is controlled through the Anti-lock brake system. The way it works is if one of your wheels starts spinning the ABS applys the brake to that wheel to transfer power to the oppsite wheel that is getting traction. If your ABS is bad then your Traction control won't work. To check it I would find a parking lot on a wet day. In an open space mash in the gas. if you hear the ABS system kick in and you don't squall the tires then your good. My guess is you won't. What I would be worried about is will my ABS work. When checking the traction control is a good time to check the ABS. Acclerate to around 15 mph, then mash the brake as your live depended on it. If you hear a motor run and feel a vibration or grind in the brake peddal, then it works.
Cheapest option would be to have the fault code read by a dealer or specialist. Its likely to be a wheel speed sensor but its finding which one that's the problem. You could disconnect each one and take an ohms reading across the connections. They should all be the same or there abouts. Change the one thats not. If your lucky the light may extinguish. If not the fault will need to be cleared using diagnostic equipment.
