Purchased a set of wheels for a 2008 HHR. The sensors that came with the car are on a set of snow rims. I purchased a set of sensors from a junk yard to put in the new rims. The tire store guy says the sensors go with the car, so I'd have to take it to the dealership to have them match the frequencys of the different sensors to the system to get the dash light off. I'm NOT refering to the process to tell the system the orientation of the wheels on the car.
Here's the deal. Sometimes the system doesn't see any tire pressure from any wheel. Other times it see's anywhere from 1 to all four wheels. The dash light goes out when it's reading all four. Anyone know why it's doing that? Is there anyway I can tell the system that it's found the sensors when it's working so it will keep working? Almost seems like the system is hunting for them and randomly finds them. I really don't know anything about it though. The only info I've been able to find is about retraining the origninal sensors, not what to do when you replace them.
