CodeInformation
MeaningP0C72: Hybrid Battery Temperature Sensor ‘E’/’F’ Correlation
Is it serious?Yes, incorrect temperature readings can lead to improper hybrid battery cooling or heating, affecting performance and battery life.
Possible causes– Mismatch between sensor readings
– Faulty temperature sensors
– Wiring or circuit issues
How to diagnose?– Check the correlation between sensors ‘E’ and ‘F’
– Test both sensors
– Inspect wiring and connections

P0C72 Meaning

The P0C72: Hybrid Battery Temperature Sensor ‘E’/’F’ Correlation code indicates that the readings from temperature sensors ‘E’ and ‘F’ are not aligned or consistent. This can lead to improper temperature regulation of the hybrid battery, potentially causing overheating or undercooling, which can affect the battery’s performance and longevity.
