DTC P0AF3-676: Sensor of Rear Motor Inverter Temperature; DTC P0AF6-675: Drive Motor Inverter Temperature Sensor "B" Circuit Intermittent / Erratic [11/2016 - ]: Description
WARNING: This page is about a different car, the 2019 Toyota Highlander, 2018 Toyota Highlander, and 2017 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.
The MG ECU, which is built into the inverter with converter assembly, detects the temperature of the rear motor inverter using the temperature sensor built into the rear motor inverter. If necessary, the MG ECU will limit inverter output to help prevent the rear motor inverter from overheating. The hybrid vehicle control ECU assembly also detects malfunctions in the sensor based on the temperature sensor values. The inverter with converter assembly detects malfunctions in the rear motor inverter temperature sensor and its wiring.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Warning Indicate |
|---|---|---|---|---|---|
| P0AF3-676 | Sensor of Rear Motor Inverter Temperature | Rear motor inverter temperature calculated by the hybrid vehicle control ECU assembly is different from the actual temperature for 10 seconds or more, and the rear motor inverter temperature is excessively high. (1 trip detection logic) |
|
Comes on | Master Warning Light: Comes on |
| P0AF6-675 | Drive Motor Inverter Temperature Sensor "B" Circuit Intermittent / Erratic | Sudden change in rear motor inverter temperature sensor output or hunting: Rear motor inverter temperature is high and either of the following conditions is met:
(1 trip detection logic) |
|
Comes on | Master Warning Light: Comes on |
HINT:
*: If only DTC P0AF6-675 is output, a temperature sensor malfunction is more likely to be the cause than a sudden change in actual temperature.
