Description
The Toyota Prius v utilizes a primary and secondary electric radiator fan system situated behind the grille to cool both the engine radiator and the A/C condenser. This fan operation is crucial for maintaining engine temperature, especially at low speeds or idle, and is controlled by the ECM via relays and temperature sensors. Failure can cause immediate engine overheating, poor A/C performance, or trigger a diagnostic trouble code, with common culprits being a blown fuse, bad relay, or a failed fan motor.
