How do you reset check engine light for the 2009 Chevy trail blazer?
Check the owner's manual.
A bad engine temp sensor can do that.
Assuming that it has a 4.3L engine, it would be the distributor.
Check for vacuum leaks.
The crankshaft sensor on a 1999 Chevy Blazer is located on the bottom of the engine, near the oil filter. It connects to the vehicle's computer and constantly updates it on the crankshaft's position.
where the map sensor on 98 blazer?
The 1993 Chevy S 10 Blazer 4.3 liter engine temperature sensor can be grounded to the engine block. You can use the temperature sensor retaining bolts to ground the temperature sensor.
The temp sensor for the ECM (engine control module) is next to the thermostat housing.
Check for codes in OBD. I have seen a bad engine coolant sensor do that.
YES, It sure can if that is the problem. FIRST you need to have the engine scanned with a OBDII engine scanner to see what CODES the computer has stored.
