WARNING: This page is about a different car, the 2017 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.
DETECTION CONDITION & POSSIBLE CAUSE
| 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.
