O2 Sensor Replacement - B2S1 on 3.0L
I got a P0050 OBDII code:
H02S - Bank 2 Sensor 1 Heater Circuit.
From the forums I've discovered:
-how to check the heater
-this is the driver side front sensor
-the driverside front sensor is difficult to replace
I'm asking a few things to anyone who has experience with this or knows:
1- where is the connector for this sensor so I can test it(where in the engine compartment)?
2-where is the sensor installed
3-how would one replace it
4-is this worth going to the dealer/shop for?
thanks for any help you can provide!
