Hello Jeremy.
When your traction light comes on it is indicating wheel spin on acceleration. To prevent wheel spin an onboard computer reduces engine power to limit the wheel spin. Some, if not most, cars equipped with this feature will also apply the brakes if wheel spin continues after reducing engine power.
Hope this answers your question.
Thank you for using Fixya!

What does "Reduced Power, Traction Fault" mean?


GM's power strategy will reduce power if it doesn't see proper charging. It does this to conserve battery power by shutting off non-essential electrical accessories. It can also mean that the traction control system is reducing engine power to avoid a skid. The traction control system gets input data from the wheel speed sensors to figure out if you're entering a skid or the wheels are locking up. One way to get you out of the skid is to reduce engine power or pump your ABS brakes. In your case you should get the trouble codes read. An ABS or traction code code could be a C, U or B code which can't be seen by a cheap scan tool or the tools they use at auto parts stores. GM had major problems with the ABS wheel speed sensors built into the wheel bearing hubs in these vehicles. The fix involved replacing the hub. So get the codes read by a pro scanner to find out which wheel sensor is setting the code. Then do the fix. Also, the P0128 is usually caused by a bad thermostat. Fix that first, because if the engine doesn't get up to operating temperature, the computer can limit some features.

My 2002 Volkswagen jetta lights on for traction control and ERP light. Car has no power.


Hi there?
The traction system is linked to the engine managment, if there a fault in the traction system it can reduce the engine power output. You need to scan the traction control system to see what fault code comes up.

ASR - Acceleration Skid Control system.
When ASR warning light blinking the system is activated itself for car acceleration skid control.


For today's typical high-torque engines, traction control (ASR) can increase both comfort and safety, particularly when driving on slippery roads or surfaces offering differing levels of grip. Traction control permits smooth starting and acceleration through the full speed range without wheel-spin or fishtailing.

ASR only operates in conjunction with the electronic accelerator (E-gas) and uses components of the anti-lock braking system (ABS). If one wheel suddenly begins to rotate faster than the others (slip), ASR intervenes in the engine management system and reduces power until the wheel stops spinning.
The ASR system represents a further contribution to active safety as it maintains vehicle traction and directional stability throughout the acceleration phase at any speed. In addition, it reduces tyre wear. Activation of the ASR system is indicated by a flashing indicator lamp in the instrument cluster.

The ESP system means the Electronic Stability Program. If the ESP lights on the dashboard permanently the ESP system is faulty. You must access the ESP Electronic Control Unit (ECU) memory for pull out all DTC (Diagnostic Trouble Codes), using diagnostic equipment connected to the data link connector of the car. Then you will be full informed about bad pieces (e.g.: front right wheel abs sensor interrupted, ...). After bad pieces replacement you will be able to erase all faults memored by ESP ECU, in other words reset the ESP system and turn off the warning lamp on dashboard.

My tahoe has the traction off light what doe that mean?


It means the traction control system has been disabled. It can be done manually by pressing the switch on the dash or by an onboard computer (meaning there is a problem). If you can't press the button to get the light off, then get it scanned. Traction control system works with the anti-lock braking system and the engine to help the driver control the vehicle in the event it should be slipping or skidding. It will activate the anti-lock brakes, help reduce steering pressure to better steer and can sometimes cut out engine cylinders to reduce the power going to the wheels to better control in the skid.

ETS LIGHT CAME ON AND CHECK ENGINE LIGHT 1997 chevy cavalier 2.4


ETS is Enhanced Traction System is used to stop wheel slip thru reducing engine output. And if the light is on it doesn't mean you will spend x amount of dollars to fix it! It just means that ETS has been disabled because you have a engine problem and the computer cannot reduce power to the wheels because the engine might stall so the computer disables the system! Now some cars come with a switch by the shifter that turns on and off the system because if you get stuck in the snow traction control will keep you from getting stuck

Want to know what a light means,and can i fix it myself


pg26b.jpg pg26c.jpg 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.
