P0E58DC/DC Converter Temperature Sensor C Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0E58 stands for a general circuit fault of the third temperature sensor in a DC/DC converter, after sensors A (P0C38 ff.) and B (P0C3D ff.). Which part of the converter sensor C watches is up to the maker. At Ford it is the inductor of the variable voltage converter, the boost stage of its full hybrids, but Ford uses only the plausibility code P0E59 for it. No manufacturer documents P0E58 publicly. The code is meant for a fault the controller can detect without being able to classify it as too low, too high or implausible, for example an unstable reference or supply. CARB requires circuit monitoring of hybrid input components. Without this reading the controller protects the converter by limiting its power, which can cut electric assist.
- What you may notice
- Hybrid system warning
- Reduced electric assist or power
- Likely causes
- PossibleSensor connection or wiring damaged or corroded
- PossibleTemperature sensor in the converter defective
- RareSensor reference or evaluation circuit in the converter faulty
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
