P0AEE on Toyota
Drive Motor Inverter Temperature Sensor "A" Circuit Range/Performance
P0AEE on Toyota vehicles indicates drive motor inverter temperature sensor "a" circuit range/performance. Au7o has documented this code across 1 Toyota model — most commonly on Highlander. Drive motor inverter temperature sensor 'A' signal is implausible or out of expected range relative to conditions.
Common Causes of P0AEE
- •Drifting/aging sensor
- •High-resistance connection
- •Wiring fault
- •Control module fault
P0AEE on Toyota by Model
Toyota Highlander(1 issue)
- Hybrid Inverter Intelligent Power Module (IPM) Transistor Solder Failure — Hybrid System Shutdown/Stall (Recall 13V396000)2006-2010
On the first- and second-generation Highlander Hybrid (2GR-FXE / 3MZ-FE hybrid), the Intelligent Power Module inside the hybrid inverter assembly carries control-board transistors whose operating temperature can exceed what the solder beneath them tolerates. The solder degrades, the transistor is heat-damaged, and the hybrid system throws multiple warning lamps. In most cases the vehicle drops into fail-safe/limp-home mode with sharply reduced power; in worse cases the power-supply-circuit fuse blows and the entire hybrid system shuts down while driving, stalling the vehicle. This is distinct from the inverter coolant pump failure and from HV traction-battery degradation — here it is the power electronics themselves, not the cooling loop or the pack. Toyota first recalled 2006-2007 cars (11V342000) and then broadened it to all 2006-2010 Highlander Hybrids built Feb 2005 through Jul 2010 under 13V396000 / Toyota campaign D0M.
