The sensor for the gauge is at the passenger side in top of the exhaust manifold.
A single green wire goes there.
Take off the wire and connect it to ground (ign. on). The gauge must move to max temp.
If it does the sensor is bad.
If not it could be the gauge, the wire or a bad ground somewhere by the cluster...
