DTC P0C39-00: Capacitor Temperature Sensor System: Notes

DTC P0C39:00 Capacitor (i-ELOOP) temperature sensor system: function/circuit malfunction
DETECTION CONDITION 
  • Any one of the following conditions is met:
    • A condition in which the capacitor (i-ELOOP) temperature sensor voltage is less than 0.05 V (less than -50 °C {-58°F})  continues for 1 s  .
    • A condition in which the capacitor (i-ELOOP) temperature sensor voltage is 4.95 V or more (90 °C {194°F} or more)  continues for 1 s  .
FAIL-SAFE FUNCTION 
  • Not applicable
POSSIBLE CAUSE 
  • Capacitor (i-ELOOP) connector or terminals malfunction
  • DC-DC converter (i-ELOOP) connector or terminals malfunction
  • Short to ground in wiring harness between capacitor (i-ELOOP) terminal 1A and DC-DC converter (i-ELOOP) terminal 1E
  • Short to power supply in wiring harness between capacitor (i-ELOOP) terminal 1A and DC-DC converter (i-ELOOP) terminal 1E
  • Capacitor (i-ELOOP) temperature sensor signal circuit and ground circuit are shorted to each other
  • Open circuit in wiring harness between the following terminals:
    • Capacitor (i-ELOOP) terminal 1A-DC-DC converter (i-ELOOP) terminal 1E
    • Capacitor (i-ELOOP) terminal 1B-DC-DC converter (i-ELOOP) terminal 1D
  • Capacitor (i-ELOOP) temperature sensor malfunction
  • DC-DC converter (i-ELOOP) malfunction
