Sensor Housing
1. Inspect the housing for cracks, physical damage, or deformation. 2. Clean and remove any dirt or debris around the housing to ensure accurate temperature readings. 3. If the housing is damaged, replace the entire sensor to prevent water intrusion or further contamination.
Sensing Element
1. Measure resistance values to confirm the sensor is accurately reading temperature. 2. Check for corrosion or discoloration that may affect its ability to register proper readings. 3. Replace the element if readings are off-specification or if any physical damage is present.
Wiring Harness and Connector
1. Visually inspect the harness for frayed or damaged wires. 2. Use electrical contact cleaner to remove corrosion or debris from the connector pins. 3. Repair or replace the harness if any wires are broken, or if pins are loose or bent.
Mounting Bracket
1. Verify that the bracket is firmly holding the sensor in the correct position for accurate ambient readings. 2. Tighten or replace any loose or missing fasteners to ensure proper sensor alignment. 3. If the bracket is bent or rusted, install a new bracket to maintain correct sensor operation.
What is an Ambient Temperature Sensor (Switch) and what does it do

No content available for this section.
Sensing Element
Common signs of failure include inaccurate temperature readings or no temperature display at all. Physical damage or corrosion on the sensor tip can also indicate the need for repair.
Housing and Mount
Look for cracks or loose fittings that can expose the sensor to moisture or dirt. Such damage may lead to erratic readings and signals that the sensor needs replacement.
Electrical Connector
A loose or deteriorated connector may cause intermittent or lost signals. Any signs of burn marks or corrosion on the connector pins suggest it should be cleaned or replaced.
Wiring Harness
Signs of a damaged harness include worn insulation, fraying wires, or poor signal transmission. A faulty harness can cause temperature reading errors or complete sensor failure.
