The C1201 error code in the Toyota RAV4 indicates a problem with the engine's control system but is only generated as a "sub code" or as the result of another error. Typically the C1201 can be accompanied by issues or error codes associated with brake sensor related or emissions control failures. The C1201 causes the "check engine" light to illuminate and will disable traction control and VSC in the Rav4. If it is scanned with either P0455 or P0441, it signals a leak in the EVAP system. This could be due to a faulty purge valve or simply a loose gas cap. If it registers along with C1441, it indicates a problem with the pressure signal from the master cylinder pressure sensor. To clear the C1201, repair the error codes that prompted it.
