I hate wheel speed sensors

[CBPO]

So a couple months back I had a wheel speed sensor go after I played in the snow.

$250.00 bucks or so - and it was replaced and everything was just fine.


Today, I went to grab lunch for the Trading Post - and as I pulled back into the driveway - all those darn lights came back on again! (ABS, Traction, Brake).


Is there a mileage mark where these things just give up living?

I'm at 82,000 now.

The pisser is the freakin' thing doesn't tell you which one goes - so you need to have it scanned.

Why couldn't they just keep them simple!?

Update - so the lights went out - but now I'm seeing some speedometer failure - it will ping from 40-45, or drop to 20mph at times when going 40+.

Anyone else ever have these issues?

Electical gremlins can be a b!tch.

I'd have to trace the signals and look for a common component. Its hard for me to believe one wheel sensor could cause your issues...

I thought the speedo operated off the transfer case speed? But that definitely sounds like more than a wheel sensor.

You could have loose wire behind the dash too. Find an electrical specialist.
