Hello, I have a 2009 Camelot with a Cummins ISL 425. My low coolant on the display and Check Engine Light is on but, overflow tank is showing at the full max level with engine hot or cold. I'm on the road in AZ currently and looking to see if I can bypass this to get back home and troubleshoot / repair? The sensor is a three wire! Because the check engine light is on the engine has derated to 70%. That extra 30% would be nice on pulling these grades here. Any thoughts? Ideas would be appreciated.
Thanks,
Rick
