How to Identify Sun Load Sensor Failure Symptoms: A Guide for Business Owners

The most common symptom of a sun load sensor failure is changes in transmission shift points and/or illuminated check engine lights.

Sun Load Sensor Failure Symptoms

Sun load sensor failure symptoms are generally characterized by high temperatures, decreased engine performance, and vehicle misfiring. Malfunctioning sun load sensors can also cause gear shifts to become rough or delayed, resulting in increased fuel consumption. Additionally, your check engine light may illuminate due to failed load sensors. To ensure proper operation of your vehicle and avoid potential damage to other components, it is best to recognize the signs of a failing sun load sensor early and replace it as soon as possible.

Common Symptoms of Sun Load Sensor Failure

Sun load sensors are components located on the alternator which monitor the amount of current generated by the vehicle. When this current is not generated in a timely manner, it can lead to problems with the vehicle’s electrical system. Common symptoms of sun load sensor failure include warning lights and codes, sensor resistance checks, and instrument cluster warning indications.

Signs of Sun Load Sensor Damaged Wiring or Connectors

When there is a fault in the wiring or connectors associated with the sun load sensor, it can result in an inaccurate reading from the component. To diagnose these issues, a visual inspection and inspection with a voltmeter should be done to identify any signs of damage. Additionally, a resistance test with an ohmmeter should be conducted to check for any open or short circuits that may be present in the wiring.

Instrument Cluster Warning Indications of Sun Load Sensor Problems

One of the most common signs that there is an issue with a sun load sensor is when the check engine light illuminates during acceleration or braking. Additionally, warning messages may appear on either an instrument panel display screen or gauge cluster when there is an issue with this component.

Alternator Warning Signs Caused by Faulty Sun Load Sensor

When there is a fault present in the sun load sensor, it can cause issues with the alternator’s voltage output when key on engine off (KOEO). This means that even when the engine isn’t running, there will still be low voltage readings from this component. Additionally, erratic electrical system readings may occur due to faulty sun load sensors.

Lighting System Malfunction Signs Caused by Defective Sun Load Sensor

When there is an issue with a sun load sensor, it can cause flickering headlights during acceleration or braking. Additionally, if either high beams or low beams cannot be operated when switching from one to another, then it could indicate that there is a problem present in this component.

Starting Issues Related To Burned Out Sun Load Sensor

When the sun load sensor is burned out, it can cause starting issues with the vehicle. Difficulty turning the ignition key to start the engine is one of the most common symptoms of a damaged sun load sensor. This issue can be intermittent, and may not always be consistent when trying to start up the car. In some cases, the engine will be difficult to start even when the key is in the right position.

Another issue that can arise from a burned out sun load sensor is abnormal shifting between different gears while driving. Unnecessary shifting into neutral or a different gear while riding at a constant speed can occur as well. This symptom could potentially be dangerous and should be addressed immediately if it occurs.

Vehicle Heating Up Problems Resulting From Broken Sun Load Sensor

A broken sun load sensor can also lead to vehicle heating up problems. Commonly, engine overheating will only occur while driving at slow speeds or in stop-start traffic conditions. Additionally, coolant temperature may rise quickly when accelerating after coming to a complete stop. This issue should be taken seriously and fixed as soon as possible as it could potentially damage other components of your vehicle.

Other Abnormal Driving Conditions Associated With Faulty Sun Load Sensor

Rough idling while stopped at red lights in gear position is another symptom of a faulty sun load sensor. Other miscellaneous driving conditions such as not processing inputs well may also occur, and should be taken seriously if they do arise.

All of these symptoms are signs that your vehicles sun load sensor has failed and needs to be replaced immediately for safety reasons and optimal operation of your car.

A sun load sensor failure can cause a variety of problems in the vehicle, from decreased fuel economy to increased emissions. It can also cause a decrease in performance and an increase in fuel consumption. The most common symptom of a sun load sensor failure is a check engine light illuminated on the dashboard. Other symptoms include rough idle, stalling, and lack of power. If any of these symptoms are present, it is important to have the system inspected and repaired by a qualified technician as soon as possible to prevent further damage.
