Be sure to know which one as you should not interchanged, may cause idling and emission problems. Generally just check if the sockets are different or same but identify the bad sensor location

These motors in Jeep's are know for week computers. Fix asap as it can lead to ECU damage. Not uncommon to wait then ECU (computer ) and all sensors need repalced. Very strange but I know of 4 Totally unrelated friends that had the same thing happen to their Jeep's. One guy is a big 4wd guy whined a shop, the other a young guy with the dealer, etc. All the same story. Ran ok so they waited. Junked the system.

Take the 2001 jeep grand Cherokee to auto zone to check again, and should know which it is one it is bank 1 top, bank 2 bottom, upstream and bank 1 top and bank 2 downstream. don't confuse oxygen sensors and air sensors. Some times the engine turns on and it reads a sensor and its not the sensor it and air leak and the sensor
is good.

If there was a trouble code, the code should tell you which one? bank 1 or bank 2, and or sensor 1 or sensor 2. Bank 1 on a v engine is the bank with number one cylinder. Bank 2 is the other bank. Some sensors are labeled upstream and downstream in relation to the cat, before or after. Upstream is senor 1 and downstream from the cat is sensor 2.
Is it clear as mud?

SOURCE: i am changing the fule

I can't remember when they changed the design but the other filter should be in the unit above the top of the pump unit (combination filter & pressure regulator) Unless you have the filter that is in-line which should be in the fuel line near the tank. (pretty sure you don't have that one).

SOURCE: How do you adjust

There are two adjustment screws at the top of each headlight. They are visible when the hood is up. Use an Allen wrench (hex) of the proper size to turn one screw to adjust the height and the other for lateral adjustment.
It is best to position the vehicle on a level surface a facing a wall or garage door. The vehicle can be about 8 feet from the wall during adjustment.
Adjust the light left/right and up/down with those adjustment screws. The head lights should point somewhat straight ahead at the same height as the headlight itself and the same distance apart.
After adjustment, park the car on the street at night, turn light son and stand about 50 feet form the vehicle to see if either light (low beams) seem too high. It would appear brighter if it is too high, dimmer if it is too low.

What causes a 2001 jeep grand cherokee dash board intruments to go wild and engine as if it wants to cut off while driving


as far as the drivability issue yes a bad o2 sensor could cause this because the computer needs the imput from the sensor to continuasly adjust the air,fuel mixture. It might be that the dash lights and instruments might be experiencing a short or loose connection. does this condition happen when you hit a big bump turn in a certain direction etc keep track of when it happens and if anything you do causes it. it will make it much easier to work with when trying to problem solve.

Hello Lubie...

I would STRONGLY recommend you get your codes read...

I TRIED ALL that TOO...

Finally my codes... said the OXYGEN SENSORS were complaining... OBD... DTC
(on-board-diagnostic... DIAGNOSTIC TROUBLE CODES)

So... of course I changed the... OXYGEN SENSORS.

The "NEW" OXYGEN SENSORS complained just as well...

I have subsequently learned the "SENSORS" are
just doing their job...

In my case reporting on a collapsed catalytic converter.
(muffler is actually a MORE common blockage).

A little hunting around... like Auto-Zone ... Napa auto...
Pep-boys... O'Reilly Auto Parts... even MIDAS might
yield FREE READINGs... (check around).

Just remember to wear your best SALES RESISTANCE...

and look up you prices on ROCKAUTO...
before you go... Hope this helps.

Error code P 0161 for 2000 Grand Cherokee Limited V8


Its related to the oxygen sensor and/or oxygen sensor heater. There are 4 sensors the Jeep is equipped with.

In most cases one of the recommended solution for all those faults is a sensor replacement, however before doing that and spending a lot of money. Go to auto zone and have them tell you what O2 sensor is bad buy it and replace it. Go back to them to have the code cleared. O2 sensors run 20-50bucks. Good Luck

Actually, just go to your local auto parts store and check the codes for free. If you go to a dealer, look forward to shelling out a minimum of $75 dollars. Most of the time its a oxygen sensor or something like that.
