Did the scan , code P0118 = eng coolant sensor was the fix, new sensor in place , drove her 50 miles at a slow pace and fast pace , code gone, she runs fine, radiator fans hits at temperature with no more engine hesitation. There are other codes , P0480 and P0481 both are related radiator fan functions , P0704 related to clutch mal function , P0803 up shift malfunction . The radiator fans are operated by an external autol relay and a manual switch for A/C operation. the tranny and clutch are fine , I ASK, DO I NEED TO BE CONCERN WITH THESE 4 CODES and can they be erased, I want the red CEL off
