O2 sensor codes
my '01 TT 225Q AMU.
reoccurring codes after being cleared , after a few miles.
P 0140 O2 sensor- bank 1-sensor 2 - no activity detected.
P 0139 o2 sensor - bank 1 - sensor 2 - slow response .
? are these codes for the sensor on the down pipe
or the one after the CAT ? or both ? are they the same part # ?
thanks for any info
