SOURCE: Code P1135 for 2002 Toyota Rav4
its the sensor on the drivers side of the exhaust manifold........ it might be an air fuel ratio meter and not an o2 sensor.. good luck jimmy

That code will not affect the drivability of the vehicle. The heater does just that: it heats up the oxygen sensor to operating temperature. You can change it yourself, raise the vehicle up, the sensor is the one on the passenger side, right after the exhaust manifold.
Thanks for choosing FixYa for advice!

I would check the O2 sensor, and if it checks bad, replace it, and clear the trouble codes. If the light comes back on, you may need to check further. .
