P2E7D: A/C Compressor Control Module Internal Temperature Sensor B Range/Performance
Standardized SAE J2012 code · P2Exx codes
What does P2E7D mean?
The ECM detects a range/performance fault on the a/c compressor control module internal temperature sensor b. 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 Sensor characteristic drifted
- Medium Sensor mounting displaced
- Low Sensor element aged beyond calibration window
