P1D7A Honda Code - Reactor Temperature Sensor Range/Performance Problem
Quick Answer
The motor power inverter (MPI) module (traction/generator) and the voltage control unit (VCU) are cooled by the motor control module (traction) which operates the electric motor control module coolant pump monitoring the coolant temperature and the temperature of various components and sends a request for operation of the radiator fan to the Powertrain Control Module (PCM). Common causes include Faulty Reactor Temperature Sensor, Reactor Temperature Sensor harness is open or shorted, Reactor Temperature Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
