Want this question answered?
behind the engine
depending on what engine you have, 4.3 v-6 or 305 v-8 or if your lucky the 350......chevy never ran a crank sensor on an engine that old. If it wont start, check spark, if you have spark, check fuel.
I have the check engine light on and the code is for map sensor on my 1999 1500 Chevy suburban
Check the lower rear end of the engine
check power to fans,if power check fan sensor!!
NO!!!
could be the oxygen sensor. that's what it was on mine.
Oxygen sensor stuck lean.
check for engine codes- it could be that there is a bad o2 sensor or something.
The check engine light is triggered by the Engine Control Module (ECM). The ECM receives information from many sensors and determines when to illuminate the check engine light.
If a knock sensor was bad, the check engine light would be illuminated and the code(s) set would indicate so.
The check engine light would come on.
