Measure resistance of sensor across terminals with unit disconnected from circuit. Sensors which do not fall within 5 percent of specification must be replaced. If sensor is within specification, check continuity of wiring to sensor. If continuity is good, control panel is defective. Note: Letters in Ambient Sensor Graph refer to vehicle series.
