I have 2000 ES300, the other day, got P1130 and P1135, need replace b1s1 sensor, so I went to order Denso air/fuel sensor 234-9021, took me few hour just unplug the electrial connector, now I am stuck with the sensor, I tried deep creep, and other liqor, nothing works, now I question my seld which way to un thread the sensor, counter clock ? I am afaird of use a lot force, also I try to turn the car on few 10 min and let is cool down. That still no help.

Anyone suggest me what should I do?

Thanks

You remove it in a counter clockwise direction. PB blaster usually does a good job with frozen fasteners. You need it to soak in for awhile.

Try this stuff. Kano Aerokroil Penetrating Oil. It works great. I just changed my B1S1 on 1mz-fe engine. It was stuck. Sprayed this stuff on 3 time over an hours time. Did some errands. Came back after a couple of hours and it broke free easily.
