the harness could have been damaged during the install.
p0135 is the bank 1 sensor 1 (driver's side pre-cat) O2 sensor heater circuit. either the harness for the sensor or the sensor itself was damaged, or the O2 sensor has died with age (usually go out in the 120-150k miles and up range.
PD - The only sensors I saw disconnected were the post cat (lower pair) ones as the lower Y collector was removed for work. I didnt not see the pre cat sensors touched (upper pair). If what you say is true then the upper sensors would have to of been disconnected during work. I need to pinpoint how this happened because it shouldn't be coincidence that I get this problem as my O2 only lasts half the life expected & set off the same day as I get work done.
Sorry for bringing this back from the dead as it has been many times, but I figured I practice necromancy on an already started thread for the same year car.
I have a P0156 code, so it's the passenger o2 post-cat. I cannot believe how involved it is to replace the o2 on this car haha...
Anyway, question is: Does the 90-94 DIY on LEXLS apply to the 95+ where you have to pull your carpeting up? Also, why is it that the OEM o2 sensor requires cutting and soldering just like a Denso universal?
Edit: Found this O2 sensor on Amazon prime cheaper than rockauto, which has the connector and everything, no need to cut/splice/solder anything.
That's the correct tool and the 3/8 should work. Make sure to soak the sensor with PB blaster or equivalent before you try to remove it. Yes you have to pull back the carpet and a OEM Denso sensor is plug and play with no cutting or splicing involved. Make sure your buying the Denso with the harness connector.
Yes. The connector is under the front carpet for the respective side being changed. CA and especially So Cal cars aren't as much a struggle to get these sensors off.
I used a 19x22mm flare nut wrench. I would estimate that it took about 22-25 foot LBS to break mine loose. Not very difficult at all. Only takes a very small dab of the copper anti seize too. The tube provided is enough to do probably 20 sensors.
The worst part of my experience was being under the car at the same time the Asian tiger mosquito was there. Was trying to make a meal of me and it did.
