Calibration Resistor / Connector: Testing and Inspection

Reference Resistor:

1. Visually inspect the reference resistor for proper installation and physical damage.
2. With the ignition (OFF) unplug the reference resistor and check for proper resistance as indicated.

Resistance should be approx. 750 ohms.

3. If the resistance value is correct reinstall the reference resistor. If the resistance value is incorrect replace the reference resistor.
