Disconnect the battery for a few minutes then re-attach. Or, call a local auto parts store and they most likely will read the code and clear it for you. also you can buy one obd2 scanner read and clear the fault coder by yourself if u mean the loud noisy horn alarm

I have the same problem few days ago, and still didn't find any solution. Can any one please help?????18

Need year.

first, you should scan the computer for the diagnostic codes. If you cannot access a code scanner, try unplugging the fuel injector wires one by one on the cylinders that do not fire. If unplugging them does not change the way it runs, it is most likely the fuel injectors. The fuel injectors should just have a clip holding them into the fuel rail; remove the clip and they will pop right out. Sometimes they could just be clogged, but they are electronic and can burn out. Running a diagnostic code scanner could indicate that a sensor is bad, like a crank position sensor; but sometimes a misfire could throw a false alarm and indicate that a crank position sensor, O2 sensor, or knock sensor arent functioning properly.

Call Toyota dealer and see if it is covered under warranty, since your car is a 2009. 0705 is a fault code for Transmission Range Sensor Circuit malfunction (PRNDL Input).

run scanner for trouble codes, some auto parts stores will do this for free
