Question about Vehicle Parts & Accessories
I replaced my coolant temperature sensor and now my truck has a high Idol! Please help!
You could reset the computer, but then it has to go through a drive cycle to adjust all the settings. It should idle high when first started and drop down after 5-10 seconds or so. The computer will adjust it after a few trips, but should be fine.

Code 37 (Part Throttle Unlock (PTU) solenoid circuit is open or shorted)
This is detected when the ECU doesn't sense near 0vdc or 12vdc at the relay when the solenoid is turned on or off. When code 37 is thrown the power limited light will not be lit and the system will not enter limp mode. With manual ****** it can throw this code for no apparent reason.
Possible Reasons for Fault Code 37
Check the wiring and connections from the logic module to the solenoid. Clean and re-grease the connectors with Dielectric Grease.
The solenoid is located in the right, front fender next to one to three other solenoids.If I remember right it is nothing more than a simple plunger activated by an electromagnet type device. It redirects air from one port through another or to another port. I don't know about finding a new one if you need it but they are built well and you could find one at pull a apart. You can also spray carb/throttle body cleaner through it and clear any clogs that might be in it.
