CAN U TELL ME WHAT THESE SENSORS DO

[ltg]

I have my truck dismantled and i can now see some things i have not seen before. Can anyone tell me what these are and what they do? thanks

That is the over temp switch found in the drivers side head front. It closes and grounds out the dash gauge when the coolant temp reaches 242 degrees. Also known as the "check engine lite"... You really never wnat to see this lite on. Take the wire off the switch and ground it and watch the dash gauge peg over past the "L" in NORMAL.... It will do this when the coolant is hot or cold grounding the wire...

#1 is i have NO IDEA i have always wondered what it is.

#2 is the temp sensor for the cold advance/high idle.

#3 is the rpm sensor. makes the tach on the dash work.

#4 is the temp gauge sending unit.

#5 is the temp light sending unit.

I can't make out what #1 is, but #2 is the cold start temp switch. When the engine is cold, this switch connects these two wires and it send power to the cold start wire on the injection pump, and also sends power to the fast idle solenoid.

yeah no. 1 looked like it was all black and when i wiped it real clean it became transparent on the front end being able to see a little circuit board or something in there.
