Engine Codes P2254 and P0059
Hey guys!
So, I've been reading different searches everywhere on a google search on the issues with having these two engine codes.
For those that don't know:
P0059 - H02S Heat Resistance (Bank 2, Sensor 1)
P2254 - O2 Sensor Negative Current Control Circuit/Open
Currently, the car runs smoothly, minus the concern that something might blow up due to the Check Engine Light being always on. Otherwise, smooth.
AT IDLE: The LAMBSE for both Bank 1 and Bank 2 are at 1.00 +/- 0.01
And the LT Fuel Trim for both Bank 1 and Bank 2 are also at really steady 1.01
For some reason, my BAMA Handheld can't read AFR or ST Fuel Trim.
If more information is needed, let me know, I'll see if I can retrieve it.
The last time I went to the dealership, they noticed my O2 sensors were corroding at their extensions (since I have LT Headers), and to forego the $700 repair cost, they drowned them in di-electric grease.
With that information, does it justify the need to replace my Front Driver side O2 sensor (Bank 2, Sensor 1), or am I good to continue driving without a worry? It has already survived 2 1200mi round trip road trips between Atlanta and Indianapolis.
If I need to replace it, should I just opt in for Ford to replace it for me for an extra $100?

Don't bother getting ANY O2 sensor from the parts store. Just get it from Ford. When I did my headers, the threads for the sensor on one of the factory logs was totally screwed up and made the sensor unusable. So I put in a Bosch. No good. Got another. Neither lasted very long at all before the light came back on. Got a Ford sensor, no more problems.
