04 Disco 133k miles. Started getting P0150 last weekend so ordered a new sensor, then started gettin p0174 and p1174 at the same time. Now getting P0150 with P0305. Can a bad bank 2 sensor cause a misfire in bank 1 ?

Thanks for your help

 

not sure but i know it can cause a check engine light>..

I'm no expert but I do know every time I see O2 sensors mentioned here the replies always say to replace them in pairs (i.e. both upstream or both downstream).

 

No O2's will not cause misfires but misfires will cause O2 codes.
Replace O2's in pairs, both fronts at the same time.
The rear O2's are for emissions monitoring only, unless you are getting a no response code for a post cat O2 leave them alone.

 

Actually Spike. O2 senors also determine long and short term fuel trims as well.
To the op, what you are asking is can you get your wife's sister pregnant by you f*cking your wife. Its impossible for bank 1 to affects the sensor of the opposite bank.
That being said, on high mileage vehicle like ours, always replace in pairs.

 

How old are your plugs, and have you replaced your factory grey wires yet?

 

Replaced plugs, wires and coil packs two weeks before my new issues started . I was getting misfires in 4 & 8 before that.

Thanks,
Pat

 

True, the FRONT O2's do, NOT the REAR O2's.

 

Spike, it seems that you and I are the only people who know that ALL the post converter sensors do, is to monitor the converter.

 

I admit that until about a year ago I thought otherwise, but after doing some research I now know better.
They are required on OBDII cars to monitor the catalytic converters, if the converters stop working then they throw a code.
"Out of range" on a rear O2 would indicate a bad cat, slow or no response means the O2 is dead.
I also found out how to delete your cats and not set off the check engine light.
When my cats go bad thats what I'm going to do.
