how to get traction control light to go out on 07 quest?

Like Jeff said, it is common for those to go bad on these model vans, when replacing it you either have to remove the sensor (which like to become frozen in their holes by rust) or be VERY careful removing and installing the hub and the hub can only go in one way, if you do it wrong it WILL break the wheel speed sensor I've seen it happen to alot of people. I used to work at a Nissan dealer as well. until you get the pieces of old broken sensor out by removing the hub again and replace the wheel speed sensor with a new one the ABS/VSC lights will stay on.

Did you buy a cheap aftermarket hub from an aftermarket parts store like AutoZone????

well most likely you have ABS or VDC on your vehicle and they sold you the wrong hub asm or you left the sensor unpluged or its damaged and you did not notice. take to a Nissan dealer or an actual repair shop and have it fixed correctly.

part# for hub is 40202-ZM70A retail is $179.15,

Part# for left front ABS sensor is 47911-ZM00A retail is $162.68

like my great grand pappy always said "you get what you pay for!" so when you go cheap trying to fix something problems can arise. Go factory OEM and your Quest will thank you.

good luck

Try disconnecting the neg. battery terminal for a few minuets.
