P0336 Crankshaft Position Sensor Range Performance
DTC P0130 O2S Circuit Closed Loop (CL) Performance Sensor 1 This doesn't mean the O2 sensor is bad .

Your best bet ,take it to a qualified repair that know how to use scan data to diagnose the problem . No code states a part be replaced. There are diagnostic test procedures for testing the electrical circuits of sensors , data parameters etc.. An trying to add refrigerant when you know nothing about A/C systems is just asking to be hurt .
my suggestion to you would be take your vehicle to a qualified repair shop ,before you hurt yourself.
It takes special tools to diagnose and repair the modern automobile an some people should not even try .
Thousands of dollars of testing equipment , not guessing , an looking for magical fixes on here . It takes years to get good at diagnosing automotive OBD fuel management system problems .Sorry mary ,but i see it every day at work . People try fixing there own vehicle ,when they can't ,then they take it to a shop . Cost big $$$$$ . it wouldn't have if they would have just take it to the shop in the first place .

year/make/model??? P0336 is a crank sensor circuit code. P0340 is a cam sensor circuit code

No symptoms posted. just how to turn a bolt. ok.
id not attempt to force it out, unless new one in pocket
right? if you break it you are DIP, dead in pavement.

if the scan tool says its good, why do that. really?
P0336? or P0340/1? why not just say the DTC does,
the ECU reports even 1 drop in 10, so did it?
most are good, but getting parts off rusty engines can be very very hard.
which engine is there, why post with out first declaring engine.
3 engines they had. 4.0L , 4.7L and diesel..

try pen oil? penetrating oil, yet? soak wait, soak wait,pray, repeat.?
WJ jeep
CKP (old SAE name CPS)
using correct name allows searching in the FSM book more easy.
the crANK SENSOR. p1690"S Use real scan tool?
p0320'S

the 4L is on bell housing top. seen below.
the 4.7 liter is above. the starter.

this?
or the 4.7L? (its totally different)




part #1 is CKP and take out bolt, and the wiggle it out.
if diesel , say so.

both codes are for crank position sensor problems. Change it.

sorry would a play with this to know for sure ,check the wiring plugs onto the sensors to make sure their not full of oil or corroded

P0340-cam position sensor malfunction (change)
P0130- O2 sensor malfunction 1/1 (change)

P0336 means Crankshaft Position Sensor A Circuit Range/Performance. Try replacing the crank sensor next.

P0113 P0340
Camshaft Position Sensor Circuit Malfunction

Intake Air Temperature Circuit High Input

p0130 is an oxygen sensor code.
p0340 is your camshaft position sensor code
p0336 is your crankshaft position sensor code

as far as the p0130 code those usually are what i call neglected sensors that do not get replaced when they should be. this sensor is expensive but worth the money as it will help on fuel mileage.

on to the camshaft position sensor, i would start here with this. replace that sensor and when you are replacing it, inspect the sensor and make sure the electrical wires going into it are in good shape. after replacing those 2 sensors, go to a parts store who can erase your codes to turn the light off and then let us know if it comes back on and then we will go from there on the repair.
