What causes traction control and ABS light to come on?
The ABS and Traction Control lights come on whenever the vehicle’s computer or PCM detects a malfunction, a faulty wheel sensor, or other mechanical failures. These warning lights do not imply anything severe by themselves but may point to a graver problem when paired with the main brake light going off.
What does it mean when your car says service variable effort steering?
Variable-assist, variable-rate or variable-effort power steering is used on a growing number of vehicles. Variable-rate steering, by comparison, applies more assist at low speed when it is needed most and reduces assist at higher speeds when it is needed least. …
What does it mean when the traction light comes on?
The traction-control light is usually a sign that your vehicle is working properly by maintaining traction on a slippery road, but it can also mean that your car has some damaged sensors or wires.
How do I know if I have variable assist power steering?
There should be a Service Parts Identification label. Check the label for the code NV7. If it’s there, then your car has variable power steering.
What does a power steering solenoid do?
In each power steering system type, the pump delivers fluid to the control valve. The valve pin attached to the orifice valve extends into the solenoid coil, and the magnetic field generated by the solenoid coil will pull the pin into the coil. This pulling action regulates the flow through the valve.
How do I clear my traction control light?
If the traction control light comes on while you’re driving, but no other warning lights are illuminated, don’t panic. Find a safe place to pull over, turn off your vehicle, and then restart it. If a fluke in the TCS system triggered the warning light, it should turn stay off when you restart the engine.
What happens when speed sensor goes bad?
One of the most common signs of a bad speed sensor is abnormal automatic transmission operation. If the VSS is faulty, the transmission may exhibit symptoms such as delayed shifts, hard shifts, and limited gear operation.
What will a bad wheel speed sensor cause?
loss of stability and traction control: if it detects a bad wheel speed sensor, the abs computer will usually disable the stability and traction control systems, as well. on some vehicles, a bad wheel speed sensor may affect other functions as well, such as hill-start assist and roll stability.
