I have a 96 acura tl 3.2 with 110 K miles, i changed the O 2 sensorsor on the drivers side and my light is still on. Did i change the wrong one!?!?

how many miles have you driven so far? just reset the light by unplugging the neg battery terminal and see if the light goes away.

AcRyte

i drove like 40 miles, and I removed the positive battery cable. I will try negative one later. Do u know what bank 1 sensor 1 is on a 96 3.2TL

First
NEVER remove the POS battery cable before the NEG-
You turn yourself into the shortest path of least resistance to Ground--thats a reallllly bad thing!!!!

You MUST remove the negative cable from the battery in order to disconnect the energy to the system- which forces a reset of the ECU- Engine Control Unit, which makes the system run a self check and should cancel the light and make the car run better.
It can take several days of driving for the car to relearn things

AcRyte

Thanks for the warning, and thats with ANY car right, never to remove positive b4 negative. I really neeed to know if i changed the wrong one. Im thinkin i changed Bank 1 Sensor 2

ANY car with Negative ground, which would be any car made in the last 40 years
Some old British cars used to be pos ground, but even they came to their senses, and the owners go back now and change all the connections to make it the much safer NEG ground type

bank 1 sensor1 is in the manifold driver side

AcRyte

that is the sensor that I changed, wonder why the light still hasnt gone off, whats the frequency or amount of time that the car will cycle the ECM

meazz1

why did you change the sensor to begin with what code was it reading? Something else could be setting the code?

Have you unplugged the neg battery cable yet?

AcRyte

i was getting code Po240 i think from memory but it said Bank 1 sensor 1 , and i unplugged it for 30 minutes. Started it up light came on 5 minutes later. Scanned it again same coe, i was hoping that meant I changed the wrong one, but i dont know wats going on. Thanks

Have you done the neg cable method yet?
Or pull the CLOCK fuse in passenger side footwell- thats the secret power for the ECU
that clears everything and car relearns whats going on now
If you had a bad o2 sensor- it may have loaded up the plugs-
Seafoam~~~ to the rescue

P0240 code, Catalytic Converter problem. catalytic converter bank 1 not efficient enough....... or Turbocharger Boost Sensor B Circuit Range/Performance.

This is what I have found searching the net.
How did know that this code means an O2 sensor problem?

AcRyte

i dont have the code with me, that was from memory, but it said oxygen sensor, thanks

01tl4tl

again- have you reset the ECU by pulling the battery NEG cable, or CLOCK fuse in passenger footwell?
The ecu does not cyle-reset itself!!!

AcRyte

PO135 is the code and I removed negative battery for 2 hours, the light came right back on. I changed the heated oxygen sensor on the drivers side, bank 1 sensor 1

TexasHonda

Code P0135 indicates a wiring or connector problem, or an open or short in the heating element of the O2 sensor. If the problem was not resolved by replacing the sensor the wiring or connector have a fault (dirt/oil on connector can cause a poor connection). Other possibility (less likely) is the replacement sensor was faulty.

good luck

AcRyte

replaced passsenger side after replacing the driver side 02 Sensor, check engine light and tcs light is still on my 96tl 3.2 throwing same code, connectors cleaned.

AcRyte

lmao, now its Po141 maybe i need to reseat the new sensor it did screw in too quick.

AcRyte

Dang Man! Initially check engine light bank 1 sensor 1 , changed driver side in 96 tl 3.2, light stayed on just changed the passenger side, light still on, now code PO141, im hearing that after the cat, WTF. Any help is appreciated. Wats the odds of all 3?, glitch? maybe i need to drive some. i havent been drivin.

thas crazy throwing code at you..

P0141-bank 1 sensor 2
