Customer Question

JA: How many miles are on the car? Has the car been starting normally?
Customer: 115000 miles and starts like a champ.
JA: Are you hoping to fix this yourself? What have you tried so far?

Hello. Welcome to Just Answer. Please allow me to assist you. The flashing AC light indicates that the RPM sensor on the compressor is not sending the proper RPM signal to the amplifier. This is either a bad RPM sensor or something inside the compressor is not allowing the RPM sensor to read the speed of the compressor shaft. Some RPM sensors can be changed, others require replacement of the compressor. If you take your 17 digit vehicle identification number to a Toyota dealer parts dept, they can look up your equipment and tell you if you have the replaceable RPM sensor. If it can be replaced, I would recommend you do this before anything else. If the light continues to flash with a new RPM sensor, you may want to consider replacement of the compressor unit.

If you have any questions, please feel free to reply. Thanks
