I replaced my upper and lower ball joints today at work, when I took off to head home my ABS, VSA, and Engine light came on. I had to take the ABS sensior out of the knuckle to change the ball joints. I'm guessing i must have got the sensor real dirty or somehting. I really dont see what could be messed up. I dropped the car off to have it aligned, maybe they can tell me something in the morning. Any info on what it could be?

 

the speed sensors have a tendancy to get corrosion inside in the wire and fail
or it wasnt put back in correctly

They are often damaged during brake jobs when the caliper gets set in the wrong place
and ooops!
About 50 bucks IIRC- many post on the subject -search

 

i drove the car about a mile or so after i fixed the ball joints then got gas. the lights actually came on after i left the gas station. would all the lights come on the dash if i hadn't tighten the gas cap all the way?

 

depending on your year- a check engine light or gas cap loose light should appear

Take it back to whoever did the ball joints-oh that was you-well complain to yourself and take it apart- find the broken part- replace

 

haha, i know. this shit always happens when i do the work myself. but there really is no other way to learn. i did have my head mechanic help me though.
