P0AF2: Drive Motor Inverter Temperature Sensor B Circuit
What to do
As P0AED — wiring first, the sensor is inverter-internal.
What this code means
The second inverter temperature sensor has failed its circuit checks — a second thermometer on a different section of the power stage, because six switches do not heat evenly and the hottest one sets the limit. Everything at P0AED applies; the letter says which section.
Likely causes
Start here
- Open circuit in sensor wiring · moderate
- Corroded or loose connector · easy

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
