my car is a 96' impreza L 2.2 and i went to smog my car yesterday however i didnt pass because of my vehicle speed sensor. ( my speed stays at 0.) would it be best to buy a cleaner to see if thatll do the trick or not? previous owner said he had the problem before and he just cleaned it and lubed it. it was fine after that. but sense the car hasnt been driven much, it "seized up" and it just needs a cleaning again. i was recommended to use brake cleaner/sensor cleaner. anyone with further advice? and any DIY on how to remove for cleaning? thanks!
