I have the 0442 error and plan to trace all the tubing down. I was hoping to find an answer here but I guess not. If the canister is cracked (possibility) I plan on gooping it with some plumbers goop from Lowes. Fixes about anything and since the leak has to be a sucking leak, the goop should gix it.

Here is what happened and how I fixed it. I thought I would post for others to learn from. The P1135 was from a failed heater element in the upstream o2 sensor on the rear of the engine. It is a 2001 ES300 with 65,000 miles. I bought a Denso 234-9021 sensor from Amazon ... the best deal I could find and was $98 delivered. I let the car cool over night and in the morning started it and backed it out of the garage to make room to work around it. I didn't know if I was going to jack the car up and work underneath. I sprayed some liquid wrench on the sensor and let it set while I rounded up a 22mm open end wrench. The elecrtical plug was not too difficult to separate. You can only get one hand to it from the top so you have to press the release tab in real hard with your thumb and wiggle the connector appart by pullung down on the connector and wires for leverqage with the rest of your hand. I got it in a few seconds. I put the 22 mm open end wrench on the sensor from the top and it was too hard to break loose. I positioned the wrench to the left side of the vehicle and got a short pipe and mallot and put the pipe on the other open end of the wrench (slipping one side into the hole) and gave it a couple raps with the mallot and the sensor broke free. After that it was simple to change out and plug the connector back in. The sensor came with some anti-seise compound for the threads. I was done in 15 minutes. I had to use a reader to re-set the engine light. I don't know if it would clear on its own. I hope this helps someone. I find tips here help me.

I have a similar problem but different. I broke a vaccuum hose coupler that was rotted and the check engine light and trac off light came on. I fixed the line and figured all was well. (The skinny lines that follow the radiator hose down on the right have poor couplings)I went to auto zone and read the obd to find P1135 which is Air fuel ratio sensor heater circuit malfunction. or failed AF ratio sensor. I turned off the lights but they came back on in a minute so I guess there is still a real problem. I was hoping to find a clue here. Any help would be appreciated. I will check the gas cap as noted above. I do not have all the ignition codes so can't help with the first guy's problems.
