Sensor Resistance

WARNING: This page is about a different car, the 2002 Cadillac Eldorado. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: For correct circuit identification and connector terminal locations, see CONNECTOR IDENTIFICATION  and/or WIRING DIAGRAMS  .

Disconnect appropriate sensor. Measure resistance across sensor terminal. If resistance is not as specified, replace appropriate sensor.
