What happens to the MAP sensor on a GMC Envoy?
If the MAP sensor on your 4.2L Chevrolet TrailBlazer or GMC Envoy is defective, you’ll see that the MAP sensor signal will not decrease as you apply vacuum to it. To be a bit more specific, the MAP sensor voltage signal will stay stuck in one value no matter how much vacuum you apply to it.
What does the Check Engine light on a MAP sensor mean?
Sometimes, a malfunction in the MAP sensor or its circuit will trigger the check engine light (CEL). Scanning the computer, you may find a P010X series of codes stored in memory. Here is a brief description of these codes: P0105: MAP sensor circuit malfunction.
Why is my MAP sensor not working on my car?
Some cars can display these codes without a code reader by following certain steps, but this will only give a numeric code that must be looked up. However, sometimes an engine code will incorrectly indicate a faulty MAP sensor. This is commonly caused by a leak in a vacuum hose or port attached to the intake manifold.

Where is the coolant below temperature sensor GMC Envoy 4.2L?
GMC envoy 4.2L can you tell me where is can find coolant below temperature sensor. There is no such sensor. I am guessing that you have a check engine light with code P0128- coolant temp below thermostat regulating temperature. This code is cause by either low coolant level, or more likely- a bad thermostat. Where is the throttle body?
