hey guys, how does the rear speed sensors look like, i got code 24 and the cost to repair from isuzu is 1300 and each sensor is almost 400 bucks, do any of u guys have any clue what they look like and if its possible to clean and if they are broken where can i buy them for cheaper, like is there other GM product to sub it rather then go through the isuzu parts. and if possible how may i fix it my self and if u guys can send me a pic or something of what it may look like? thank you guys.
