SOURCE: i have error codes p0156 p0161

  Check the wire harness near the top of the engine in the rear. They were good for rubbing through on the trans fill tube bracket. Judging by the code you have 4 sensors. you would be interested in the drivers side rear sensor.

Bank one is toward the front of the vehicle. Sounds like the heated oxygen sensors have gone bad. The Oxygen Sensors are located in the exhaust pipe and require a special socket to remove and replace.

SOURCE: MY LEXUS IS200 SE engine management light came on

What was the code? lean mixture? If so make sure there is no leak in the exhaust. I have worked on a lexus suv, but it was an 89. It had a lean mixture code. After examination I noticed a exhaust leak which was not apparent at first, there is a section in the exhaust the is very thin, and prone to leakage, causing the lean mixture code.

SOURCE: I need to know which O2 sensors are which: Bank 1

bank one upstream oxygen sensor on exhaust manifold bank two oxygen sensor after catalytic converter.tell me what code you are getting.bank 1 sensor 1 fuel system is too rich fuel pressure too high fuel pressure regulator leaking or more than 1 fuel injector leaking. fuel contaminated.check spark plugs if black carbon color fuel system too rich. if you getting code bank 1 sensor 2 check for air leaks in the exhaust system, air leaks intake manifold.look for vacuum lines leaks,look for vacuum leaks pcv valve and hose and make egr valve not stuck open or gasket leak.

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

https://www.fixya.com/cars/t3949859-firing_order_diagram_02_jeep_liberty

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.

P0161 CODE ON JEEP LIBERTY 2003


Posted by Anonymous on Jan 25, 2013
why post to 2013? ELIAS? why not start your own post.
and not mix, engine sensors with HVAC blower heaters. hark.
the OP never once stated cars drive line.
and matters 100%
my guess is a jeep liberty with 3.7L and 2.4L 4 banger.
the answers vary by engines.
so if 161, is set the heater in bank 2 is bad, rear OXY sensor.
O2 Sensor Heater Circuit (Bank 2 Sensor 2)
the pcm measures the heater current flow
when it reads zero the sensor is bad or the wire is cut.(or rusty)

guess 2, is that late poster thinks
P0161 codes are HVAC codes
no it is not.
P0 codes are USA federal base codes.
and are for smog not dash HVAC heaters.
nice guess but dead wrong.

in most cases the 02 sensors is just bad.
the heater inside it just burns open.
all do that , every one... not one lasts
the life of engine, ever.

here ill read it to you, the SM. for 3.7L V6
gas engine, USA book and car....

Trouble Code: P0161 (3.7L V6 VIN K Auto)
O2 (B2 S2) Slow Response

Number of Trips to Set Code: 1

CCM Details

Trouble Code Conditions:
ECT Sensor less than 147?F and BTS signal within 27?F of the ECT Sensor (cold engine), engine started, system voltage over 10.5v, engine running at idle speed for over 12 seconds, and the PCM detected the O2 signal was more than 3.0v for 30-90 seconds.

Possible Causes:

ASD relay output (power) circuit to the heater is open

O2 heater ground circuit is open or O2 signal circuit open

O2 heater element has high resistance, is open or shorted

PCM has failed

2004 jeep liberty P0139 code


PO139:O2 Sensor ckt Slow Response(Bank 1,sensor 2).This would be the odd side cylinders(1,3,5) and the 2nd oxygen sensor form the cylinder head.The sensor may be contaminated,or the heating element(on a 3 or 4 wire sensor) may not be working well.a good auto parts store should be able to show you a picture of where it is(the store will probably give you a printout if you buy the part form them!)

2002 jeep liberty cmp sensor bank 2 short to ground


That one is pretty self-explanitory. You need to find where the Bank 2 Camshaft Position Sensor (CMP) circuit is shorted to ground and repair the short.

Where is banl 1 sensor 2 located on a 2006 jeep liberty


bank 1 is always the same side of the engine as the number one cylinder. Bank 2 is the other side of the engine. Sensor 1 is always before the catalytic converter. Sensor 2 is always after the catalytic converter.

What code are you getting?

I have a 2002 jeep liberty with engine light on. Took it to autozone for a diagnosis and code PO161 came up. I know its an O2 sensor, It says to check circuit fuse. Where do I find the circuit fuse and how...


P0161 is 02 heater Circuit ( Bank 2 Sensor 2 ). There is no mention of any Fuse and there should not be .Circuit refers to the two wires extending from the jeeps computer dirrectly to the 02 sensor in question which would be in this case Bank 2 sensor 2. So the computer is transmitting a signal to the 02 sensor and not receiving a sgnal back it automatically thinks the circuit is at fault, when it is not.It is not receiving any Data back from the 02 sensor because the sensor is defective and needs to be replaced. If you replace one sensor you should replace all 4 of them. If you only replace one then it will be transmitting Data back to the computer at a much faster rate than the other 3 old ones and this could cause more problems and more codes to be set by the computer.Remember to have all the codes cleared from the computer after all repairs are compleated, This will turn off the check engine light. Good Luck and have a good XMASS.
