Which engine there are 3,

G16, J20 and H25. 4 bank , 4bang, v6

all 02s have a connector about 1 foot from sensor. all.

my guess is you have the SOB, v6, it is a pistol

it looks like the engineer was asked, see if you can make it near impossible to change ! then make it the only connector on the

car with the lock , working backwards ! HE WON.

here is 1 page, just for this, issue, only one on the web. btw.

getting them off the hidden brackets, is no JOY

takes like an hour each.


and do ask questions.

replace only the front, (unless smog man makes you do rear)

or you get P042x codes,.

I did go to Auto Zone and they gave me the diagnosis error code is (PO2631)but they don't know what is it means.

that is because that number is WRONG
P0xxx is the format , yours is too long. P0 p1, OR P2.
use any modern, scan tool, to read the codes.
be sure to write them down more carefully.
ok i see your error, you added a 0 . (i think i got it)
there is no zero, P2 codes are factory codes.
p0 is federal codes,
and autozoned, is clueless to them, they;'d need and fsm on every car made to decode all P2 codes on all cars. a hopeless path.

why not just look them up in authoritative sources
like, SUZUKI or and avoid the ZONED.
answer, USA answers 06 GV
2631 is the oxygen sensor, failure,(or its wires damage, in all cases)
V6 engine code, 2.7Liter
bank 2, sensor one.
decoding that , bank 2 is the bank not on cylinder 1 side.
the right bank is bank2
its the top right (upstream) sensor is bad.

right means from drivers perspective.

best path is here
the price 4 bucks
the book is here

the FSM has your answer.

B1 -B2
1 -- 2
3 -- 4
5 -- 6

bank 1 is left, bank 2 is right. per below, on all v6 by Suzuki

Where is o2 sensor fuse located on 2005 grand vitara

some have 4 sensors
what engine.
what country and if in calif , that too, is a country. By EPA regs.
the H25 engine is here.
got a 2.5L? v6

there are 4 sensor, 2 front , 2 rear of cat.
or can be 3, if the rear merge to 1 cat. but not this one.

the front sensors are hard to change
and the connectors , lock up backwards from all other connectors
on the car.

if you post country and engine,
anwers get better 100x.
we cant guess that.

this page covers front no rear, rear is child easy to fix.
rears only change if you get P0420s. (lazy cat errors)
the fronts control fuel mix. hot, closed loop.

I have a 2006 suzuki grand vitara,are the oxygen sensors the same in either bank of the engine?

Well, the upstream sensors are the same and the downstream are the same - so it takes two of each.
For the record you should never have to replace more than one or two sensors at one time. And trouble codes do not tell you the sensors have failed.

Where Are The sensor Banks On The 2004 GC

Grand Cherokee oxygen sensor locations for 4.0 and 4.7 engines



Four wires (circuits) are used on each O2 sensor:

  • 12–volt feed circuit for the sensor heating element
  • Ground circuit for the heater element
  • Low-noise sensor return circuit to the PCM
  • Input circuit from the sensor back to the PCM to detect sensor operation

O2S Sensor removal Never apply any type of grease to the oxygen sensor electrical connector, or attempt any soldering of the sensor wiring harness.
1. Raise and support vehicle.
2. Disconnect O2S pigtail harness from main wiring harness.
3. If equipped, disconnect sensor wire harness mounting clips from engine or body.
CAUTION: When disconnecting sensor electrical connector, do not pull directly on wire going into sensor.
4. Remove O2S sensor with an oxygen sensor removal and installation tool.

02S Sensor installation
Threads of new oxygen sensors are factory coated with anti-seize compound to aid in removal. DO NOT add any additional anti-seize compound to threads of a new oxygen sensor.
1. Install O2S sensor. Tighten to 22 ft. lbs. (30 N·m) torque.
2. Connect O2S sensor wire connector to main wiring harness.
3. If equipped, connect sensor wire harness mounting clips to engine or body. When Equipped: The O2S pigtail harness must be clipped and/or bolted back to their original positions on engine or body to prevent mechanical damage to wiring.

Hope thats help (remember comment and rated this).

Where is the bank 2 sensor 1 located.

Oxygen sensors are always numbered like this:

Bank 1 sensor 1
Bank 2 sensor 1
Bank 1 sensor 2
Bank 2 sensor 2

some manufacturers use a kind of shorthand that reads different, but means the same thing:
Sensor 1/1 or O2s 1/1
Sensor 2/1 or O2s 2/1
Sensor 1/2 or O2s 1/2
Sensor 2/2 or O2s 2/2

Bank 1 is always the side of the engine where cylinder number 1 is located and, of coarse, Bank 2 is the opposite side.
On a 4 cylinder engine, there is only 1 bank and it is always referred to as Bank 1.

Sensor 1 is always the upstream sensor (The one located BEFORE the catalytic converter)
Sensor 2 is always the downstream sensor (the one that is located AFTER the catalytic converter.

Most GM engines have #1 cylinder located on the left bank, (or Driver's Side) of the engine,

So, the answer to your question would be that you are looking for the sensor located before the catalytic converter on the right (or Passenger Side) of the truck.

PO135 Error Code

Bank one stands for the same side as the number 1 cylinder. Sensor 1 is the first sensor in the bank, (closest to the engine or upstream).
In most cases you will find it on the drivers side\left hand side of the engine and above the catalytic converter. Look for it on the lower portion of the exhaust manifold.
