Newbie Code 37 question
I get two error codes on my 1988 Y-code 5.2L Ram W100. A code 15 "No speed/distance sensor signal" and a code 37 "part throttle lock/unlock solenoid driver circuit (87-89)". I found the speed/distance sensor but I have no idea where to look for the lock/unlock solenoid driver. My Haynes manual is no help. Any thoughts?
Also, could either of these codes be the cause of my truck nearly stalling at stop lights when warm?
