Lecture outline that covered this topic was based on a handout and the following note in my lecture:
A good temperature vs. voltage chart displaying the difference between the
two voltage curves inside the computer (the dual level temp sensor).
17. Tech A and tech B are monitoring voltage on the coolant sensor of a SMEC equipped Chrysler. They have checked the voltage cold (60 deg. F) and have found it to be at 3.00volts. After leaving the vehicle running for a while and grabbing a cup of coffee, they return and recheck the engine temperature with a heat gun and find it at 160 deg (F)
To their amazement, they find the voltage on the coolant sensor now reads 3.2 volts.
Tech A says the coolant sensor must be faulty. Tech B says the computer must be bad.
