SOURCE: Possible o2 sensor 2002 GMC Onvoy

O2 sensors indicate unburned oxygen in the exhaust sysytem. Bad O2 sensors causes fuel mixture to run rich. It causes fuel consumption and your emmissions test will not pass. Check for vacuum leaks check the manifold.check for a misfiring cylinder, a burned exhaust valve that is leaking compression. replace the O2 sensor or sensors. Some cars have 2 . One for the intake another for the out take. If it reads a code for the Map sensor along with the O2. It is better ifyou replace both sensors. But I think that the problem lies in the oxygen sensor or sensors. Pleae vote my answer if this helps.

SOURCE: Oxygen Sensor jeep liberty

well first off depending on the year you could have up to four.now the easiest thing is to check trouble codes by turning yor key three times.now move it to the first position it moves to.thats were you need to end at all three times.now from that position you will move it quickly to the position when the accessories and idiot lites lite,right before it hits the starting position.so do that three times and wala if you got a problem with it your gonna know which one of the four you need to replace.follow the imortal saying of if it aint broke dont fix it ,oh ya to locate just look at other answer

Have codes indicating bank 2 running lean(po174,po153,po159) also have codes for misfires on all cylinders. Does the misfire trigger o2 codes or does bad o2 sensor cause misfires?


misfire could cause o2 codes. o2 sensors are measuring the oxygen in the exhaust - if you're sending unburnt fuel through there (like a misfire), it would throw the value way off. if you're getting a 'lean' error, I would first suspect a bad fuel injector. But you are having a misfire on all cylinders... I would then look at the ECU as it may be having issues sending the 'open' signals to the injectors.

Jeep liberty codes


Possible causes
- Warm Up Three Way Catalytic converter deterioration or malfunction
- Exhaust system leaks
- Loose front or rear HO2Ss
- Faulty front heater O2 sensor
- O2 sensors harness is open or shorted
- O2 sensors poor electrical connection
Tech notes
As the code description implies the P0422 code means that the vehicle's control module has detected that the three-way catalytic converter is not working properly (is not as efficient as the factory is expecting). Replacing the oxygen (O2) sensors may sometimes fix the code, but in most cases the catalytic convert needs to be replaced to fix the problem. If the P0422 code is combined with other codes, try fixing the other codes first.

CODES P0300, P1128


po300 is random miss fire doubtful two O2 sensors bad at one time most likely coolant temp sensor is bad causing engine to run rich this will cause O2 sensors to throw a code(thats what they are there for..exhaust gas temp. and raw fuel) running rich will also fowl spark plugs(=miss fire) P1128 ??

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

Jeep liberty 2005 3.7 v6. Doesn't want to start,


This sounds like a fuel pump problem, if the pump is bad and it does not give the engine the right pressure the car wont run and if it does it will not have power and can give an o2 code due to lean mixture, you may have a bad o2 but this would not make car not start, the o2 does not play a role in the engine until engine temp is up and in closed loop. have the fuel pressure tested i would bet is is low or no pressure, check the fuel pump and the relay .start there

What fuse needs to be replaced for 2/1 O2 sensor on 2005 jeep liberty?


there is no fuse for the O2 sensors. The PCM supplies power to the heater and the sensor.

Is there a trouble code that indicated there is a problem with that sensor?

2002 Jeep Liberty P0174 code and mech has changed the o2 sensor


Can't tell you exactly what is wrong but the one thing you said is of concern...Map sensor should not be full of oil. If it is, I'd want to know why. In finding the reason for that, you may also find the reason why you are having a problem.
Jeep uses two kinds of engine crank venting. you either have a pcv valve or an orifice controlled system. If either are obstructed it can overpressure the crankcase and cause all kinds of problems.
Years of experience tells me this isn't something I can guess at and be 100% sure I have the right answer but based on what you said, I'd look there first!
