A/C Evaporator Temperature Sensor Circuit Low Input

What This Means

The A/C evaporator temperature sensor voltage is below minimum threshold. This sensor prevents the evaporator from freezing by monitoring its temperature.

Common Symptoms

• A/C ices up
• Inconsistent cooling
• No A/C operation
• Check engine light on

Common Causes

• Faulty evaporator temp sensor
• Wiring issue
• Connector corrosion
• Frozen evaporator
• PCM circuit failure
