Bank 1 is whatever bank that Number 1 cylinder is at. Bank 1 Sensor 1 is before the cat converter, Bank 1 sensor 2 is behind the converter.

Code P0155 in a 2002 jeep liberty what it is?

this is covered in the FSM book by jeep.
per engine. non stated, so.....?????

p0 are federal codes. (a standard)
and is oxygen sensor reads wrong.
B2 S1 is bad.
S1 is the front sensor.
bank 2 is the engine bank that has #1 cylinder.

the heater in side is blown out.
or the wires to it are bad..melted, cut, or connector to it rusty.
the ECU only knows, the heater fails to conduct current.
it sees the heater dead.
replace it or fix the wires to it.
same on all cars this. only bank varies.
next time post engine size. the line up.
some inline engines run 2 banks too, like calif cars do. not just V engines.
the left front cylinder is #1 on v6 Bank 1 IS LEFT

seen here.
if this is your V6 engine, the 02 (b2) is on right , front (means upstream) bad.

does this help, the inline on calif engine, inline it is rear top sensor. B2S1, on split exhaust manifolds. for calif.

What can cause code p0135 on 2004 jeep grand cherokee laredo

one more thing to check after going through all this stuff, which actually these guys seem to have a wealth of knowledge on. seriously. jeep for some reason has a notorious situation that so many mechanics and enthusiasts miss. .. it took me 3 weeks to figure this stupid mess out for my x's daughter, who hates me by the way, but i do it because i'm a nice guy. try the cam sensor. sounds silly i know. but i see it more and more as being the answer to all these mysteriousness ailments to these hard running jeeps. my daughter is getting ready to drive and wouldn't you know it she wants a grand cherokee. lol. I have an 87 yj. but its a weekend mustang killer. and i luv to stomp tuners on the highway. its on youtube. got a lil sbc, with a t-5 borg warner hybrid shorty, 1,2,3, fast throw, 4,5. way long. 4:11 rear with detroits. not 4wd. its so fun. had to put upper and lower lakeside drag bars. but anyway..... :) cam sensor give it a thought. sometimes 1 and 2 banks are hard to differentiate for some reason when reading codes. still trying to figure that one out.???

Location of the bank 1 sensor 2 on th engine?

"banks" refer to the sides of the engine. Bank 1 is always the same side of the engine as cylinder number one. Bank 2 is always the other side of the engine.

"Sensor" refers to upstream or downstream of the catalytic converter. Sensor 1 is upstream of the cat and sensor 2 is downstream of the cat.

Bank 1 sensor 2 would be the same side of the engine as cylinder number 1 and downstream of the catalytic converter.

Were is the o2 sensor located in bank 1 sensor 2

is it a 4 cylender, or 6. if its a 4 cylender the bank 1 sensor 2 is the sensor closest to the cadalatic converter, on the exhaust. if its a 6 cylender you will need to contact honda, and see which bank is one, and which bank is 2... The banks refer to the side of the engine they are talking about. a v6 will have 2 banks, drivers bank and passengers bank, sensor 1 is always the sensor on the exhaust closest to the engine, sometimes even on the manifold, and sensor 2 is the one slosest to the cadalatic converter.. hope this helps, o2 sensor explaining can be a little difficult

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).
