Question about 2002 Toyota RAV4
Car Drags jerks as it moves. There is a round light on the dash board "check engine" Scan result said PO161 and P1135, O2 sensor heater circuit bank 2 sensor 2 and air fuel sensor heater circuit response malfunction
CODE PO161 IS REGARDING OXYGEN SENSOR BANK2 SENSOR2 WHICH IT IS LOCATED IN THE BOTTOM RIGHT SIDE OF THE CAT ON THE OUTPUT OF THE CAT.REGARDING CODE P1135 IS FOR AIR FUEL RATIO OXYGEN SENSOR MALFUNCTION BANK1 SENSOR 1. MY OPINION CHANGE THE SENSOR BANK 2 AND RESET THE FAULT USING A SCANNER AND DRIVE IT. I BELIEVE WILL SOLVE THE PROBLEM.

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
