so the ground wire on my chip broke and the truck went into limp mode. i was about 7 miles away from my house and truck barely would climb a hill. anyways i got home fixed the wire hooked up to my code reader and i got a low boost sensor i tryed to clear it and it wont let me. where and what does this sensor do. i also had an injection pump code that i cleared because i didnt want to see it.

 

If you fixed the problem then give it a few days. The OBDII system will clear itself of codes which are no longer a problem after so many key and drive cycles. Dont bother trying to start and shut down over and over in the driveway either because that wont work. I'm not exactly sure how it works but the truck has to be driven to be considered a cycle.

 

ok thank you for the imfo
