Warning Lights coming on

[Ryan Decker]

Not sure what may be causing it but it seems to be intermittent which suggests a connection issue somewhere in one of the lines. I bought electronics cleaner and plan on going through all the wires with it but wanted to get a suggestion on what may be causing all the lights to come on every now and then (not frequent).

1. ABS light
2. Service 4WD
3. Traction Control light

Not to mention i have had a Tire pressure warning light go on and off while im driving since i bought it. Tire pressure is fine as well as the tire. I did a scan with an advanced Snap-on scanner and it all points to the front left wheel speed sensor or other. Any suggestions on what to test out before i start replacing things?

The sensor could be bad, or the tone ring inside the assembly is really really dirty.

After testing it out with a scanner - seems to be the rear left wheel speed sensor. Replacing it now, thanks.
