Error message, exhaust emissions failure

[robnokia]

I keep getting the error which seems to be common amongst the v8 vantages
I reset it using a dongle but it keeps coming back on about every 400 miles.

The error code says po153 oxygen circuit slow response bank 2 sensor 1.

Do you think I should replace it? Anyone got a part number as I can get denso and ngk from work

If it's normal I'll gladly leave it. It just seems to be happening a bit quicker each time. Also worried if I replace it same will just happen again with it been more of a characteristic rather then a fault

It sounds like your Primary O2 sensor is on its way out. The primaries are responsible for monitoring fuel trim. I would replace this sensor. Secondaries are less of a concern.

+1 it will mess with already terrible fuel economy as well

do you not think, that just perhaps, there might be a fault with the sensor ??
