O2 Sensor Problems
Hello to All..
I have a 2010 VR6 with 146,000 miles and recently I was getting the P0420 code ( efficiency ) issue with Bank 1. So, I go online and order a plug-n-play replacement sensor.
And BAM! I get the P0130/P0135 ( heater circuit issues ) but NO efficiency codes. So, I get in touch with the supplier I bought from, they say sorry and send out another sensor.
Guess what? Again, another heater circuit issue.
So, how is it I get 2 sensors and BOTH have heater issues but no efficiency issues? Do I have an underlying issue somewhere or just a crappy supplier of Chinese sensors?
Any help would be greatly appreciated!
