Have now got the following code on my 2003 1.8 - P0141-04 O2 SENSOR HEATER CIRCUIT OPEN (BANK 1 SENSOR 2)
Is this a fault with the rear O2/Lambda sensor in the exhaust just before the Cat?

update on my p0141 , read code with a u480 code reader , checked no2 O2 sensor with my multi meter and found no continuity on heater circuit the 2 white wires , rang pentagon vauxhall for the price of a new sensor £120 rang local breaker £40 , went on car parts connexion £43 from nidd vale motors (to good to be true I thought ) rang them up new genuine part , arrived yesterday fitted today , have driven my car for 50 miles so far no light and no code on reader
Cheers Ste, not sure whats going on. don't know if this has just come on after the exhaust being changed, whether they have damaged the wiring while changing it or knocked it while trying to get it out of old pipe , I will have to have a look. Old code disappeared for a few days but now getting the P0141 and P0170 Fuel trim malfunction. Swapped the front O2 sensor and Maf and coil pack with my mates, cleared codes inbetween each changeover but fault still returned. Sensor 2 must be the rear one???
oh you mean when they did the flexi pipe
yes mate, cant recall seing that code before, will have to check the logs.
pm you instead
Sensor changed and running perfect, with a lot more pick up and acceleration, fingers crossed again
