Question about 2004 Toyota Prius
I have a 2004 Prius and the check engine light came on. We took it to the dealer and they said the code was P3108. They reset it and could not get it to come back on. They said they thought the visor mirror light may have been on , draining the battery. We turn off the switches to the visors to prevent this but a few days later the light came on again. We were at a body shop getting a few dings repaired and he tested for us and the code he got was the POA93 - Drive Motor performance. He reset it. We called the dealer and they toke the information down and said bring it in if the light comes on again. Has anyone experience this? Any thoughts what might be causing it?
P0A93 is an inverter cooling problem. The inverter is cooled by a dedicated cooling system, which consists of an electric water pump, cooling fan, and radiator. This cooling system is independent of the engine cooling system.The mechanic should check if there is sufficient amount of coolant for the inverter, check if the coolant hose is not bent or clogged, if the water pump / cooling fan motor connections are ok, and of course if both of the cooling fan motors are OK.
P3108 is generally loosing communication with the A/C system control module. This can usually be solved by checking the wires and or the converter inverter assembly.
