" You may need to try to wedge something small in the locking tab on the plug so you are able to pull with 1 hand while someone holds from the top with 1 hand (neither of you can get 2 hands in there) I also suggest getting the sensor online where you can buy it for around $150. That's for original eq. Denso, the only thing I would recommend. I just noticed you have an ES rather than RX. Don't know how much different that will be, have to jack it up and see. That code is only the heater, so it's not urgent, won't hurt anything, may only run faintly rougher when cold."
W here should the wedge go into the locking tab? Outside the tab I suppose? It is driving me nuts to disconnect the harness plug. Thanks.
