P2E80A/C Compressor Control Module Internal Temperature Sensor B Circuit Intermittent/Erratic

P2E80 indicates that the air conditioning (A/C) compressor control module has detected an intermittent or erratic signal from its internal temperature sensor B circuit. The module monitors this sensor to protect the compressor from overheating, and when the signal jumps or drops out, it sets this code and may disable the A/C clutch to prevent damage.
