Height Sensor Test
WARNING: This page is about a different car, the 1996 Oldsmobile LSS, 1996 Oldsmobile Eighty-Eight, and 1996 Buick LeSabre. However, it is still accessible from the selected car via links, so may be relevant.
- Turn ignition off. Disconnect height sensor connector. Turn ignition switch to RUN position. Measure voltage between specified terminals of height sensor connector. See HEIGHT SENSOR VOLTAGE TEST
table.
- If battery voltage is not present, take action specified in table. If battery voltage is present at all wires, check for poor connection at height sensor connector. If connection is okay, reconnect height sensor connector. Turn ignition switch off, then to RUN position. Wait 35-45 seconds. If compressor does not run, replace height sensor.
- If compressor runs, raise and support vehicle. Ensure rear wheels are supported as close as possible to trim height specification. See REAR RIDING HEIGHT
under ADJUSTMENTS. Disconnect link from height sensor metal arm. Move height sensor arm assembly upward.
- Allow 17-27 seconds for delay. If compressor does not run, replace height sensor. If compressor runs, but struts do not inflate, perform procedures in COMPRESSOR OPERATION TEST
under COMPONENT TESTING and SYSTEM LEAK TEST
under SYSTEM TESTING.
- If compressor runs and struts inflate, slowly move height sensor arm assembly downward until compressor stops. If compressor does not stop, replace height sensor. If compressor stops, continue to move height sensor arm assembly downward.
- Allow 17-27 seconds for delay. If struts do not deflate and vehicle does not lower, replace height sensor. If struts deflate and vehicle lowers, perform HEIGHT SENSOR
adjustment under ADJUSTMENTS.
