P0138 Check Engine Light
 

Hi folks.

Just got an error code on my 2005 Ford Escape Hybrid with 90K miles:

P0138 - Bank 1 Sensor 2

This I believe, refers to the O2 Sensor in the vehicle, only problem is, I'm not sure WHICH.

I understand that Sensor 2 generally refers to the O2 sensor AFTER the catalytic converter so I think this is stupid question but if anyone can check the file attached and confirm that its #3 that needs to be replaced, that would be greatly helpful!

Thanks everyone!

Hi folks, just want to update this post very quickly...

As it turns out, I did some snooping and decided to re-seat all sensors on the catalytic converter.

Once I did that, the fault code(s) disappeared completely. :shade::shade::shade:

I will mention, websites do mention changing O2 sensors after 75-85k miles.

I believe the repair manual said to change them at 100k miles although I'm unsure about this.

Anyway, take care everyone! ;)
