The crankshaft sensor should be located on the GM V6 engine right behind the bottom
pulley at the bottom. There was a service bulletin for check engine lights on my S-10 about a
clearance problem with the sensor. Check it to make sure the end hasn't got
a hole worn in it. Hope this helps.

I have a 2003 GMC Envoy and the check engine light comes on peridically. Auto Zone checked it and Code 0128 was the alleged issue. However, where is the sensor? No one seems to know the location of the...


This code relates to low coolant temperature not the 02 sensors. You should change your thermostat, it's stuck open and is not allowing the engine to properly heat up.

By the way, there are 2 92 sensors on Envoys and Trailblazers. One of them upstream is in the engine compartment right off the exhaust manifold, easy to replace. The other one downstream is next to the transmission drain plug in the exhaust pipe.

Check engine light on - 2003 gmc envoy XL


That code represents a lower than expected reading for temperature (coolant). First thing to do is check your coolant level, as if it is low, then the sensor can not read correctly. Second, you may have a thermostat that is stuck open, allowing the coolant to cool off too much. The sensor should be mounted on top of the engine, near the thermostat housing.
