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 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
