07 pontiac g5, what does service traction, traction off. This light comes on. Car then dont want to idle, transmission shifts hard and jerks into gear. What does tht mean?


This is all electronically controlled by the PCM - engine computer an EBCM - electronic brake control module . An this will affect the transmission as well because everything is all hooked together electronically .
Engine Traction System Indicator
TRAC OFF
The instrument panel cluster (IPC) illuminates the TRAC OFF indicator when the electronic brake control module (EBCM) inhibits the Engine Traction System due to a malfunction in the Engine Traction System. The IPC receives a GMLAN message from the EBCM requesting illumination.
Your best bet is take it to a ASE certified repair shop or a GM dealer , Chevy , Buick , Cadillac . seeing how Pontiac isn't any more .

Lexus x470 the vac trac light is on


Do you maen your "VSC" and "TRAC" lights are illuminated while driving your car? If so, what this means is that your onboard computer ststem has detected a malfunction in your Engine Control, and/or your Transmission Control, and/or your Brake Control systems. You must use the proper diagnostic equipment and procedures to access your onboard computer network to determine the nature of the malfunction, and diagnose and repair accordingly.

I have a 02 Cavalier that when your driving the Trac off light comes on when the light is on it runs rough and shifts hard but if i put it in park turn it off and restart it it's fine


There is a malfunction in you antilock brake/traction control system. When the TRAC light is on, the computer is trying to tell you either 1. That the traction control is active and is controlling your brakes, engine and transmission to stop a wheel skid, or 2. There is is a malfunction in your traction control system.

In the first case above, the TRAC light will only be on for a few seconds until the conditions causing your wheels to slip no longer exist. If the light is staying on even though there is no way your wheels are slipping or skidding, then this is a malfunction. You must scan both your Powertrain Control Module (PCM) and your Antilock Brake System (ABS) module to properly diagnose a problem with this system.

VSC TRAC AND TRAC OFF LIGHT AND CHECK ENGINE LIGHT ON ALL CAME TOGETHER


Very common problem. There is a problem with your traction control system. The most likely cause would be a malfunctioning vehicle speed sensor or a wheel speed sensor. You will have to scan your computer control systems to find out exactly what is causing it. There will be fault codes stored in the engine control module (ECM).

The ABS lite, No Trac Lite and Service engine lite keep coming on


When the Service engine soon, ABS and TRAC lights are turned on at the same time the computer control units for the engine and the ABS/TRAC systems has sensed a fault in the electronic controls of the engine and/or the emission system and the ABS and Traction Control system (part of the ABS system). When this happens you will seldom feel the car engine run any different or the car drive any different. There are about 200 possible faults that turn the Check Engine light on, the fault in your car is likely a part called the VSS sensor to know for sure what the problem is you must have the system tested; Kragen and Autozone parts stores do this testing for free

My trac light is on, on the dash board. Where is the wheel sensor located ?


Your vehicle is equipped with 4 of them. They are located at each of the 4 wheels. There are other reasons that the Traction Control light can come on...wheel speeds sensors are not the only reason, athough they are the most common. The traction control system works with the engine/powertrain control system and with the antilock brake system. A bad wheel speed sensor will usually also turn on the Antilock Brake (ABS) light. If the Check Engine light is also on, you could have an engine control problem causing the Trac light to come on.
.
If the Trac light is on by itself, you may just have the traction control turned off. The Trac Off switch is located on the steering column.

If none of the above solves your problem, then you will have to scan your computer system to find out why the light is on. ( i.e. failed wheel speed sensor...but which one?)

On my Toyota Sienna 2008, my check engine light, Trac Off and VSC lights are one. Why? How do I fix it?


On most Toyota's that are equipped with Cruise Control (Vehicle Speed Control or "VSC") and with Traction Control System (TCS or "Trac") all of these lights will come on at the same time if the Engine Control Module (ECM) determines that there is a fault in the engine management system that 1. Prevents the engine from being properly controlled. 2. Prevents the VSC from being properly controlled 3. Prevents the TCS from being properly controlled 4. Any combination of items 1,2, and 3.
Most of the time it is caused by a single fault in the engine management system. Fault codes are codes that are output by the ECM to let a diagnostician know which of the many systems, that are monitored by the ECM, is malfunctioning. To find out what the actual cause is, you must scan the ECM for fault codes then use this information to begin diagnosis of the system that the fault codes point to.

What would be the cause for the VSC, TRAC OFF, and CHECK ENGINE light to all be on at the same time why the car was just worked on?


there are dozens of reasons for this to happen, but when these lights are on it is alerting u to the fact that a malfunction has occured in the electronics of one or more of these systems,(ABS/Trac Control, ck engine) have the electronic control system scanned for trouble codes to determine the casue of these fault lights, Autozone and Kragen do this for free in most states..
