Isit Absolutelecessary to remove the cover when changing the variable valve timing solenoid bank 2 or Left Bank on a 2006 Kia Sedona I am able to get the bolt will I be able to wiggle it out of there

it is on the front bank of the engine near the cam shaft

These codes have to do with the CVVT(continuously variable valve timing)solenoid. I guess it is a 2.4 liter engine, the solenoid is located right above the power steering pump at the #1 cylinder in the cylinder head. If it is the 3.5 liter it is located on top of each cylinder and is accessed after the intake plenum is removed. Either way, the solenoid controls valve timing of the exhaust cam via the solenoid which uses oil pressure to advance or retard the timing. The first step is to verify proper weight of oil and level. If the engine is over due for service, get it done. If the oil is not an issue, then the solenoid is becoming sluggish in advancing or retarding the camshaft and should be replaced.

P0026 KIA Intake Valve Control Solenoid Circuit Range Performance Bank 1

this indicates a problem with the variable camshaft timing and possibly requires reprogramming PCM module
assume the engine warning light is on? does the engine run normal?

P1136 NISSAN - Intake Valve Timing Control Solenoid Valve Circuit Bank 2
Possible causes- Intake valve timing control solenoid valve bank 2 circuit is open or shorted.
- Intake valve timing control solenoid valve bank 2 circuit connectors
- Intake valve timing control solenoid valve bank 2 Tech notes Since the Intake valve timing control solenoid valve uses oil flow to control timing, dirty oil can cause the valve to stuck open or close. Before replacing the valve, change engine oil and filter and reset engine code.

Removal & Installation

3.5L Engine

1. Before servicing the vehicle, refer to the precautions at the beginning of this section.
2. Record the radio anti theft code data.
3. Remove or disconnect the following:
   
   Negative battery cable Engine cover Accessory drive belts Idler pulley Crankshaft pulley Power steering pump pulley Belt tensioner pulley Upper and lower timing belt covers
   
4. Support the engine with a floor jack and remove the engine mount.
5. Rotate the engine to align the camshaft sprocket timing marks with the cylinder head cover timing marks.

6. Remove or disconnect the following:
   
   Auto tensioner Timing belt
   
   

   Fig. Timing belt and related components-3.5L Engine
   
   

To install:

1. Ensure that the engine is set to Top Dead Center (TDC).
2. Prepare the auto tensioner for installation by compressing it in a vise and installing a retaining pin.
3. Install the timing belt in the following order:
   1. Crankshaft sprocket
   2. Idler pulley
   3. Left bank exhaust camshaft sprocket
   4. Left bank intake camshaft sprocket
   5. Water pump pulley
   6. Right bank intake camshaft sprocket
   7. Right bank exhaust camshaft sprocket
   8. Tensioner pulley
   
   
4. Install the auto tensioner. Do not remove the retaining pin at this time.
5. Check that the crankshaft and camshaft timing marks are aligned correctly.
6. Rotate the crankshaft 1 / 4 turn Counterclockwise .
7. Rotate the crankshaft 1 / 4 turn Clockwise to return the engine to TDC.
8. Loosen the tensioner pulley center bolt.
9. Apply 44 inch lbs. (5 Nm) torque to the tensioner pulley as shown and tighten the center bolt to 32-41 ft. lbs. (43-55 Nm).

10. Remove the auto tensioner retaining pin.
11. Rotate the crankshaft 2 revolutions Clockwise , then wait 5 minutes for the auto tensioner to adjust.
12. Measure the auto tensioner rod as shown. If the measurement is not 3.8-4.5 mm, then repeat the belt tensioning procedure.

13. When the auto tensioner measurement is correct, install or connect the following:
    
    Engine mount Upper and lower timing belt covers Belt tensioner pulley Power steering pump pulley Crankshaft pulley Idler pulley Accessory drive belts Engine cover Negative battery cable
    
14. Reprogram the radio anti theft codes

P0066 = air assisted fuel injection (AAI) control circuit malfunction.
P1380 = VVT Solenoid circuit malfunction bank 1
P1385 = VVT Solenoid circuit malfunction bank 2
P0353 = IGNITION SIGNAL COIL C FAULT. P1380 Variable cam timing solenoid A malfunction. Bank 1 cam solenoid located underneath intake manifold. The bank 1 solenoid is under the passenger side valve cover on the V8. On the V6 it's under the valve cover as well but the intake needs to be removed.
