Hello...2nd month of ownership of my '03 Disco, 62k.....I just replaced all 4 O2 sensors due to throwing codes...Wow...does it run great now...smooth...but...I am getting Code P0140..scan show an issue with Bank 1 #2 Sensor signal, If I clear the code is stays off for about 10 miles...I tried checking the connections, everthing seems ok...thoughts?

 

Who did you buy the 02 sensors from? Might want to call them and let them know what is happening, see if they will replace the sensor or if they have any idea why this is happening.

 

VB sale last week for $59 each...I will give them a call...

 

Sorry...AB.....VB is Victoria British, thinking of my MGB....
