SOURCE: Check engine light came on.
P1135 means that your O2 sensor has gone bad. The O2 sensor on the Toyota's are called Air fuel sensor's. If you have a 4 cylinder engine, the O2 is on the exhaust down pipe before the catalytic converter, and if it's a V6 it the O2 sensor on the fire wall side along the down pipe from the exhaust manifold. (sensor 1, bank 1) Good luck and keep me posted, check the wire harness. The wire harness could have corroded or burnt from the exhaust, but most likely it's going to be a bad O2. Keep me posted ,be glad to help

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. .
