I work at a small independent body shop and one of our employees decided to pull the reinforcement bar on a customer's 2007 ES 350 without securing/wrapping up the loose wires.

What ended up happening was the hook on the frame machine came loose and got caught on the wiring harness for the smog vent sensor. While the actual connector stayed plugged into the sensor, three of the wires got pulled out. I paid 15 bucks to get the techinfo.toyota.com site wiring diagrams so I can figure out what color wires go where, but I'm not sure if they're accurate. They also show two light blue wires without specifying which one has one stripe or two stripes. Can anyone take and upload a photo of what it's supposed to look like please?

And for your viewing pleasure, a couple pictures of the wonderful result of pulling carelessly:

The sensor and the connector/harness in question side by side


The back of the harness showing the wires that have been pulled out


And as a sort of bonus... after this happened, another employee ended up cracking the radiator while bolting on the air condenser. The jinx continues...

 

oh man...oh man..oh man..

 

Just wondering if you were able to get the wiring diagram to rewire the plug for the smog sensor. I happen to be having the exact same issue as I am rebuilding my 2008 ES 350. If you were able to solve this problem can you share with me the solution?

 

I've attached the lexus wiring diagram in color for the AC system. the smog sensor is page 2 of the pdf. also the wire color code is explained in the 02.pdf. hope this helps

 

Thanks! Big help... That is just what I needed... I will try and decipher it all and begin the rewiring project. Will let you know if it works out.

 

Your info was perfect! It worked extactly as needed... REALLY appreciate it !
Thanks

 

Smog Ventilation Sensor for 2014 LEXUS ES300h

Back to the old thread , I am fixing exact issue on 2014 LEXUS ES300H , apparently this car also uses same sensor by DENSO 013650-040 in cars from 2008-2015 ( previous revision 013650-010 has also 5 wires used on older ES300 - ES350 2006 - 2011 models )
and my wires are also color coded. I will send picture to this forum once fixed and tested.
