fault code p0161

Rockauto do a 5% discount if you enter a code in the "where did you here about us" box in the shopping cart. There is usually one on the website linked below but it is currently just out of date. If you google rockauto discount you should find a current one easy enough.

Usually a good code here... http://www.markviii.org/LOD2/products_services.htm

P0161 HO2S Heater Performance Bank 2 Sensor 2

Assuming a 4.0L engine, bank 2 is cylinders 4-6 sensor two is the second (after cat) sensor.

Rockauto code good till the 18th of this month...

its the 4.7l V8, the guy at leo muller told me to unplug each sensor 1 at a time and check for codes, i did that and the code still appeared on each on and engine light was still on, is there a different way to tell which sensor is gone

Just did a scan of my WG/J manual, all 2367 pages and have found that P0161 refers to the right hand bank rear sensor.


You will find that the sensors are all the same it's the legth of cable thats probably differn't, go for the one with the longest lead. Bosch do a universal one for the 4.7 WG part #0 258 986 602 you just have to hook up the old plug to it, can be a pain to do sometimes.
Go RockAuto and save some money or if in a real hurry Repco or any of those auto parts stores have them, Bosch, Denso.

Yep diff length lead & diff plug shape for front/rear sensors.
Best replacing all if going through rockauto, saves on shipping & if ones nackered others are probably nearly nackered.

Heaps of post on here regarding the dreaded 02 sensors.

I'm pretty sure you can still download the rather substantial .pdf manual for free via the link I posted on the Useful Grand Links sticky, you just have to right click the link on the third paragraph "Find more about 2001 Jeep Grand Cherokee WJ Workshop Repair and Troubleshooting Manual here" and select save as. I'm downloading it now and it looks good so far.

Don't pay for it!
