Chassis Acceleration Sensor - Spectra
NOTE:
Only component testing procedure is covered. For Chassis Acceleration (CA) sensor system and circuit testing procedure, see appropriate SELF-DIAGNOSTICS article.
CA sensor is located in right side of engine compartment, behind strut tower. Turn ignition on. Backprobe and measure voltage between CA sensor 3-pin harness connector terminal No. 3 (Red/Black wire) and ground. See Fig 1. Check for voltage spike (less than one volt) while tapping CA sensor bracket. If no voltage spike is observed, replace sensor. For CA sensor removal and installation, see CHASSIS ACCELERATION SENSOR under ENGINE SENSORS & SWITCHES in REMOVAL & INSTALLATION article.
