My "check engine" light is on. Took it to someone who checked it for me. He said I need a sensor P1135. Replacing it is fairly simple. Where do I find the sensor and how do I install it? Is there a diagram that I can read and follow as for direction? The check engine light is on all the time. I'm due for a smog check and I need to repair the problem. Thanks!

You'll definitely need to fix this before you go for your smog inspection. This is a common issue on these engines, so I suggest going to Youtube and performing a search to see if there's some info. I bet you'll find something because of the high failure rate. Good Luck

i agree but to be sure you should get a real diag from a real tech at a real shop. there are several issues with 1135. the sensor is not cheap and you want to be sure you are doing the right thing Roy

Hello Roy and Bret, Code P1135 is for Bank 1 sensor 1 O2 Sensor heater circuit failure. Its the one code on a Toyota that is always correctly identified as a failure. Disconnect the O2 sensor check the two black wires at the sensor side of the harness for continuity if they are open the sensor is bad. Use a Denso sensor, NGK or SNG sensor that is a direct fit not a universal fit sensor.
