Component Resistance

WARNING: This page is about a different car, the 2002 GMC Cab & Chassis Sierra and 2002 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

Connect DVOM between specified terminals at component or at transmission in-line 20-way connector to transmission. Measure individual component resistance at specified temperature. See Figure . See COMPONENT RESISTANCE SPECIFICATIONS table. If resistance is not as specified, replace appropriate component. See Figure .

⁽¹⁾	Resistance is measured between specified terminals at component or at transmission 20-way in-line connector. See Figure .

⁽²⁾	Resistance is measured at 68°F (20°C).

⁽³⁾	Resistance is measured at 212°F (100°C).

⁽⁴⁾	Greater than 250 k/ohms.

⁽⁵⁾	Resistance is measured at speed sensor.

⁽⁶⁾	Resistance is measured at 77°F (25°C).

⁽⁷⁾	Resistance is measured at 302°F (150°C).

⁽⁸⁾	Greater than 10 megohms.

⁽⁹⁾	The resistance of this device is necessarily temperature dependent, and will therefore vary far more than any other device. See Fig 1 .
