2006 Jeep Liberty R428 I4 DOHC is what type of VM engine? All VM engines seem to be a 700 series set of numbers.

I believe this is for 1.8L engine, serpentine belt. If you have a different belt for each component, that is a different issue? With multiple belts, the component usually has a pivot bolt, you loosen the bolt, then move the component to release or increase tension on the belt, then tighten the bolt.
With a serpentine belt, the tensioner does that for you.

The engine size is 3.7 but to answer your question, Chrysler products quit using external fuel filters many years ago. The last filter for Jeep was probably in 1998.
There is a sock filter before the pump, but that is a dealer part.

From wikipedia: Engine 1.5 L B5-ZE I4 DOHC
1.6 L B6-ME I4 SOHC
1.6 L B6D I4 DOHC
1.8 L K8 V6 DOHC Transmission 5-speed manual
4-speed F4A-EL automatic Mazda MX 3 Wikipedia the free encyclopedia

Depends which engine is in your car. The cavalier had 5 diff engine models. You will need to check part numbers. Most bolt on and maintenance parts are most likely the same. Major parts most likely much different. Contact your local auto part store and reference the two parts in mind of changing.
Here's an engine list.
2.2 L LN2 OHV I4
2.2 L L61 DOHC I4
2.2 L L42 DOHC I4
2.3 L LD2 DOHC I4
2.4 L LD9 DOHC I4

No year , no country, now that is a challenge.
Gas or Diesel?
my guess is you dont know what engine you have or year car?

it has gear drive cam. (4.0L)

lets see, 1984 AMC to 2001. called the XJ ,is car XJ??????

3.7L
is yours diesel

That engine is a 4 cylinder and they all have belts.

this is covered in the FSM book by jeep.
per engine. non stated, so.....?????

p0 are federal codes. (a standard)
and is oxygen sensor reads wrong.
B2 S1 is bad.
S1 is the front sensor.
bank 2 is the engine bank that has #1 cylinder.

the heater in side is blown out.
or the wires to it are bad..melted, cut, or connector to it rusty.
the ECU only knows, the heater fails to conduct current.
it sees the heater dead.
replace it or fix the wires to it.
same on all cars this. only bank varies.
next time post engine size. the line up.
some inline engines run 2 banks too, like calif cars do. not just V engines.

• 2.4 L PowerTech I4 (gasoline)
• 2.5 L VM Motori R 425 I4 (turbo diesel)
• 2.8 L VM Motori R 428 I4 (turbo diesel)
• 3.7 L PowerTech V6 (gasoline)

the left front cylinder is #1 on v6 Bank 1 IS LEFT

seen here.
if this is your V6 engine, the 02 (b2) is on right , front (means upstream) bad.

does this help, the inline on calif engine, inline it is rear top sensor. B2S1, on split exhaust manifolds. for calif.

only the FSM covers that. in the front of FSM.
each engine type its in a different place. sorry.
and different engine plants can do it different ,world wide.

no year stated
no series LC.stated
nor engine stated. LC has 13+ engines world wide.
at least.
in fact, the LC had the largest choice of all, by model.
the engine type is incoded in the vin in USA>
no country stated, either.
