Step 13 - Inspect Engine Coolant Temperature Receiver Gauge Resistance

WARNING: This page is about a different car, the 2002 Toyota Tundra. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Connect the test leads so that the current from the ohmmeter can flow in order specified, see Fig 2 . This circuit includes the diode.

Measure the resistance between terminals.
