My 94 dodge ram 1500, 5.2L, runs okay but began using lot of fuel. Had trouble codes 37, 32, and 51. Cleaned throttle body and checked for vaccum leaks or bad hoses. Code 32 gone away. Cleared code 51 which according to Haynes manual is not supposed to make the check engine light come on. Their is no code 37 in the Haynes manual for a gasoline engine on the 94 Ram. Their is for diesel engine. What is it, where is it at and how do I correct the problem. 51 I know is the O2 sensor. Truck runs great, shifts fine , but is still using more fuel than normal. Been reading about code 37 and transmissions, don't think my problem is there. Any help ?

Question type: Maintenance & Repair

Cannot get the Code 37 to clear, can disconnect the battery and the code 51 clears, The
code 32 has not come back but 51 comes back. 37 does not go away. Engine light will
not come on after starting until the truck warms up , usually about a 5 to 7 mile drive.

Found bad coolant hose and water pump, changed oxygen sensor (only has one, upstream). All codes clear , except code 37. Transmission is going into overdrive. Check engine light not coming on but code 37 is still in system. Not going to worry about it. Truck has 211,763 miles. Going to drive it. Thanks for the help ??
