I've owned my 2007 XJ VDP for 1.5 months and 2,500 miles. The car has 38,000 miles and recent started throwing these two "O2 voltage low" codes. I had a similar problem a few years back on my Honda Element and it was and old/failing O2 sensor.

Car runs perfectly, aside from the check engine light. I'm interested in thoughts from the forum...

 

Check wiring and if OK change sensor(s).

Clear codes and see if they recur, first, if so inclined.

 

Anyone here know which of the four O2 sensors is bad based on these codes? Believe the codes reference Bank 2 Sensor 1.

 

Believe this is the drivers side - pre cat sensor.

Anyone know who makes the OEM sensors?
