SOURCE: 2003 Jeep Liberty heater fan problem

It is the blower motor resistor. Look under the passanger side dash and locate the fan housing (looks round and black in color. Then locate the resistor it will be in that housing usually withtwo ten millimeter nuts or two simple screws holding it in. unplug the harness to the resistor and remove the resistor. Part store price is approx. 50.00. Note: on aftermarket (not Jeep) resistor sometimes you have to modify the housing a little to get it in. Hope 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

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!)

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.
