 Howdy <i got two codes po128 ,and po135.I changed thermostat,back flushed system,installed fresh coolant,then replaced o2 sensor 1 in bank 1.now the bosh sensor which came for this car ,would only plug in one way,I noticed after resetting trouble lights that po135 came back on.So as I was looking at o2 sensor I noticed on bosch sensor that a was going to c in car plug ,and c was going to a ,same on B /d side,I removed plug on new sensor and wired it to a to a b to b so on.My question is this sensor that I was sold for this car a buick century 3.1 with 70,000 miles,auto trans,2002 model .Is the same bosh model recomended for this car.Is it possible that the new monitor should be wired the way it was where a on monitor went to c on plug and so on,or did I mess up this sensor by plugging it in the way it came with a going to c on car,and c going to a on car.it would have been all correct if it had been possible to plug it in the way it came except it was 180 degrees off when it plugged in causing a to c and cto a.Did I ruin this sensor by the plug being backwards or should I have left the plug the way it was with a on sensor going to c on car???Did I fry new sensor maybe??Or????please help ,thanks in advance>Marvin

Marvin; Sounds like you've got a universal sensor instead of exact fit. Hopefully, all you have done is wire it incorrectly. I'd suggest you take it back, and buy a direct fit sensor. I refuse to sell the 'universal' sensors.

 Yes I know it was sold as a direct fit and I installed it ,it was sold by oreilly and I looked online and it was A bosch 13474 just like all the online suppliers sell as oem replacement.I am a decent mechanic ,I have been rebuilding two stroke engines for forty yrs and making a living as PWC mechanic last 18yrs.I did notice that a went to c after thee code popped back up,did I ruin the new one by plugging it in the only way it went ,even though I found out later it was not a to a and so on.I thought perhaps since it was bosch not delco it maybe was made different ,after researching ob2 I realize it all has to be universal and wired the same as it is government std.does PO135 sound like the o2 sensor is bad or is the heater different???please and thanks for your help.I will pull o2 sensor and try and take it back>Marvin

Marvin; Year, make, model, eighth digit of the VIN #, and I can check the part number.
btw; P135 is heater circuit, bank one, sensor one. (upstream, bank one...need engine size).

13193 This is AutoZone's Bosch part #. I was hoping to get you a CarQuest #, but the site isn't working right now.
If this doesn't look right, that it would plug in without modification, give me the dob of your car. On the driver's door, there will be a sticker that shows month and year date of production.

tthats exactly what it looked like only it would only plug in one way a 180 degrees off of the way the original denso made gm part plugged in,with a to c and b to d and so on.one of the spades has a longer slot and the only way it would plug in was wrong according to the letters on the new and old o2 sensor,thanks>Marvin

I have exactly the same problem. I have a 2001 Buick Century and this Sensor shows as a direct fit. Initially got a PO131 Code when I plug it in the "only way" it would fit and here the C was 180 degrees off. Then I flipped it around and got PO135 error. I'm trying to figure out what the issue is. Did you have any luck getting this to work?

This is an old thread. You need to start a new question of your own. We can't address multiple vehiccles in the same thread. It's way too confusing.
