P2E7F: A/C Compressor Control Module Internal Temperature Sensor B Circuit Low
Standardized SAE J2012 code · P2Exx codes
What does P2E7F mean?
The ECM detects a circuit low fault on the a/c compressor control module internal temperature sensor b circuit. Reading cannot be used reliably for control.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Common causes
- High Signal wire shorted to ground
- Medium Internal sensor short
- Low Connector pins corroded - high contact resistance
Likelihood is a general estimate across vehicles; your make and model may differ.
