The most common cause of the DTC (Diagnostic Trouble Code) PO320 is either a defective CKP (Crankshaft Position) sensor or poor connection. Inspect the Crankshaft Position (CKP) sensor circuits and harness for a possible chafe on ground.Wiggle test the CKP sensor circuits with the engine idling to see if tapping or wiggling on the harness will result in a misfire or stall condition.

code p 0336 refers to crankshaft position (CKP) sensor--range / performance problem===causes --insecure sensor/rotor---air gap---wiring---CKP sensor
I have no listing for the E118 code to help you with
find an accredited service shop that has experience on your make of vehicle and they will tell you the code reference and verify the 0336 code as well

P0038 - HO2S Heater Control Circuit High Bank 1 Sensor 2
P0128 - Coolant Thermostat (Coolant Temp Below Thermostat Regulating Temperature)
P0336 - Crankshaft Position Sensor Circuit A Range/Performance
P0386 - CKP Sensor B Circuit Performance.
your most likely need to replace the crankshaft sensor and probably will take care of the 0336 and 0338 codes.
you then need to check your coolant level, if low fill and look for leaks, if not low, most likely replacing the thermostat will correct other two codes

This answer covers 1999-2005 Cadillac Deville, Eldorado & Seville.
Example Engine:
2002 Cadillac Seville STS 4.6L SFI DOHC HO 8cyl.

This engine has (2) Crankshaft Position (CKP) Sensors: the Upper sensor is CKP sensor B, and the lower sensor is CKP sensor A (this is included for the OBD-II DTC codes - P0385 references Sensor B = upper CKP sensor, whereas P0335 references the lower CKP sensor (sensor A)).

Both crankshaft position sensors are located in the front of the engine just above the oil filter adapter. To access both CKP sensors, jack up vehicle on the passenger side, remove the oil filter, and the oil filter adapter, including the Engine Oil Pressure (EOP) switch. See illustration.

The ARROW points toward Front of Car.
1. Upper Crankshaft Position Sensor (B).
2. Lower Crankshaft Position Sensor (A)
3. Engine Oil Pressure (EOP) switch
4. Engine Oil Level switch
The Oil Filter is the can-type object below the oil filter adapter, which includes the EOP switch. Recommend: remove oil filter with an oil filter socket/strap wrench, since it's close to the oil pan.

Diagnostic Test Code (DTC) P0316 means that a cylinder misfire was detected within the first 1000 revolutions of the engine crankshaft after engine startup. This code will always be stored at the same time with freeze frame data and a fault code for the offending cylinder.
This is where DTC P0305 comes in.
This code means that cylinder #5 is the cylinder that is causing the misfire.
Coils and plugs are only two of the many possible reasons for a cylinder misfire.
The possible reasons for both of these codes are:
> Damaged crankshaft position sensor
> Ignition system (Primary or Secondary)
> Faulty fuel injector or fuel injector control circuit
> Poor fuel quality (will usually cause MULTIPLE cylinder misfire codes)
> Base engine faults (burned valves, low compression, damaged lifters or cam, blown head gasket, etc.)
> Damaged/malfunctioning PCM

NOTE: The LEAST LIKELY cause is the PCM. A damaged Crankshaft Position Sensor will usually cause problems on ALL cylinders, not a single cylinder, however it IS possible if the sensing ring is damaged.

The crankshaft position (CKP) system variation learn feature is used to calculate reference period errors caused by slight tolerance variations in the crankshaft, and the CKP sensors. The calculated error allows the powertrain control module (PCM) to accurately compensate for reference period variations. This enhances the ability of the PCM to detect misfire events over a wider range of engine speed and load.

The code P1336 is for a Crankshaft (CKP) and/or Camshaft (CMP) position sensor input signal to PCM concert. It is triggered if the input signal to the PCM for either of these sensors is erratic. Per the factory service manual, this can be due to:
- a damaged PCM
- damaged CKP sensor
- damaged CMP sensor
- base engine
- harness concerns.

The service manual suggests checking the following items:
- harness routings,
- alterations,
- improper shielding,
- or electrical interference from other improperly functioning systems.

To properly check the operation of the CMP and CKP, you'll really need an oscilloscope. The code is probably being triggered due to a faulty sensor or connection and not something that just needs to be reset.

Step / Action / Yes / No

1. Did you perform the Diagnostic System Check-Engine Controls?
Yes: Go to Step 2
No: Go to Diagnostic System Check - Engine Controls

2. Preform the CKP system variation learn procedure. Refer to CKP System Variation Learn Procedure. Did you complete the action?
Yes: Go to Step 3
No: Go to Diagnostic Aids

3. Clear the DTCs with a scan tool.
Turn OFF the ignition.
Start the engine.
Operate the vehicle within the Conditions for Running the DTC as specified in the supporting text.
Does the DTC run and pass?
Yes: Go to Step 4
No: Go to Step 2

4. With a scan tool observe the stored information, Capture Info.
Does the DTC run and pass?
Yes: Go to Diagnostic Trouble Code (DTC) List
No: System OK


Diagnostic Aids:
The CKP system variation values are not stored in the PCM memory after a learn procedure has been performed. If the actual CKP variation is not within the CKP system variation compensating values stored in the PCM, DTC P0300 may set.

The CKP system variation learn procedure is also required when the following service procedures have been performed, regardless of whether DTC P1336 is set.
An engine replacement
A PCM replacement
A harmonic balancer replacement
A crankshaft replacement
Any engine repairs which disturb the CKP sensor relationship

If the CKP system variation learn procedure cannot be performed successfully, check for the following conditions and correct as necessary:
A damaged reluctor wheel
Excessive crankshaft runout
A damaged crankshaft
Interference in the signal circuit of the CKP sensor
A coolant temperature that is not within the Conditions For Running the DTC
The ignition switch is in the ON position until the battery is drained
A PCM power disconnect with the ignition ON may erase the stored value and set the DTC P1336

Hope helps.

Hello ayltaz: My name is Roger and I Will help you. The first code p0303 relates to a cylinder misfire in #3 cylinder. This could be a bad plug or plug wire. The second code relates to the crankshaft position sensor. You can just replace the sensor or have this problem tested as to replace a sensor because of a code can get real expensive and may not fix the problem. Should you need further help please just ask. Please rate the answer. Thank You for using Fix Ya. Roger

CKP System Variation Learn Procedure
IMPORTANT: For additional diagnostic information, refer to DTC P1336.
1. Install a scan tool.
2. With a scan tool, monitor the powertrain control module for DTCs. If other DTCs are set, except DTC P1336, refer to Diagnostic Trouble Code
(DTC) List for the applicable DTC that set.
3. Close the vehicle's hood.
4. With a scan tool, select the crankshaft position variation learn procedure.
5. Observe the fuel cut-off for the engine that you are performing the learn procedure on.
6. The scan tool instructs you to perform the following:
^ Apply the vehicles parking brake.
^ Block the drive wheels.
^ Cycle the ignition from OFF to ON.
^ Apply and hold the brake pedal.
^ Start and idle the engine.
^ Turn OFF the A/C.
^ Place the vehicle's transmission in Park (A/T) or Neutral (M/T).
^ The scan tool monitors certain component signals to determine if all the conditions are met to continue with the procedure. The scan tool only
displays the condition that inhibits the procedure. The scan tool monitors the following components:
- Crankshaft position (CKP) sensors activity - If there is a CKP sensor condition, refer to DTC P0335 or DTC P0336.
- Camshaft position (CMP) sensor activity- If there is a CMP sensor condition, refer to DTC P0341, DTC P0342 or DTC P0343.
- Engine coolant temperature (ECT) - If the engine coolant temperature is not warm enough, idle the engine until the engine coolant
temperature reaches the correct temperature.
7. With the scan tool, enable the crankshaft position system variation learn procedure.
IMPORTANT: While the learn procedure is in progress, release the throttle immediately when the engine starts to decelerate. The engine control is
returned to the operator and the engine responds to throttle position after the learn procedure is complete.
8. Slowly increase the engine speed to the RPM that you observed.
9. Immediately release the throttle when fuel cut-off is reached.
10. The scan tool displays Learn Status: Learned this ignition. If the scan tool does NOT display this message and no additional DTCs set, refer to
Symptoms - Engine Mechanical. If a DTC set, refer to Diagnostic Trouble Code (DTC) List for the applicable DTC that set.
11. Turn OFF the ignition for 30 seconds after the learn procedure is completed successfully.
