What is P.A.I.R. valve? - 2002 Suzuki VL 1500 Intruder LC

Question edited for clarity.
Question moved to model category.

It is the intake manifold tuning valve that is stuck and fortunately not the Inlet valve itself.

This is fault 27 info
27. (00011011) Fabric Softener Valve Fault
The Motor Control Module has measured a voltage from the valve diagnostic circuit that
indicates the fabric softener valve (with Yellow Clip) is faulty. The most likely cause is that
the valve harness has not been connected correctly or the valve is open circuit. See fault
code 49 for service procedure.
49. (00110001) Cold Valve or Cold Valve & Hot Valve Faulty
The Motor Control Module has measured a voltage from the valve diagnostic circuit that
indicates the cold valve or both the cold and hot valve is faulty. The most likely cause is
that the valve harness has not been connected correctly or the valve(s) is open circuit.
Primary Source: Wiring.
Action: Check the valve harnesses are correctly fastened to the valves and
the motor control module or the pins are not bent backwards.
Secondary Source: Water Valves.
Action: Measure the resistance of the cold and hot valve coils.
Tertiary Source: Motor Control module.
Action: Replace the Motor Control module.

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.

make the engine runs for about 30minutes before adjusting the valves,
valve clearances:
intake valve = 0.20mm(0.008 in)
exhaust valve = 0.25mm(0.010 in)
for reference only when the engine is cold,
valve clearances:
intake valve = 0.25mm(0.010 in)
exhaust valve = 0.30mm(0.012 in)
engine specs: mitsubishi 4g13 1.3L (if you have same engine)

Valve is not identified.
Cold water shut-off valve, TP valve, check valve, mixing valve, drain valve are the usual suspects associated with electric water heater.
Gas water heater has additional valves: gas shut off valve and gas control valve thermostat.
Check valve, TP valve and mixing valve probably need replacement.
If drain valve is leaking, put garden hose cap over end.
Shut off valve probably has a bit of blockage, or is not completely open. Try closing and then opening shut-off valve all the way, and if problem persists, replace or clean out valve.

What kind of noise? Are you sure the noise is from a valve or is it inside the tank caused by sediment build-up inside of tank?

If you can supply me with all the codes your vehicle is showing, I can assist you. As far as the P1111 DTC goes I have listed the info below with some possible solutions.

P1111- Intake Valve Timing Control Solenoid Valve Circuit Bank 1

Intake valve timing control solenoid valve is activated by ON/OFF pulse duty (ratio) signals from the ECM. The intake valve timing control solenoid valve changes the oil amount and direction of flow through intake valve timing control unit or stops oil flow. The longer pulse width advances valve angle. The shorter pulse width retards valve angle. When ON and OFF pulse widths become equal, the solenoid valve stops oil pressure flow to fix the intake valve angle at the control position. The code is triggered when an improper voltage is sent to the ECM through intake valve timing control solenoid valve. 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.

Possible Causes:
- Intake valve timing control solenoid valve bank 1 circuit is open or shorted.
- Intake valve timing control solenoid valve bank 1 circuit connectors
- Intake valve timing control solenoid valve bank 1
- Dirty Oil

Possible Solutions:
- Change Oil
- Replace Intake valve timing control solenoid valve

Not sure on your engine so heres both types. :-) Hope it helps. Cobra
Positive Crankcase Ventilation (PCV) Valve — 3.0L (2V) Removal and Installation

1. Disconnect the positive crankcase ventilation (PCV) valve tube quick-connect from the PCV valve.

CAUTION: A new PCV valve must be installed if removed from the cam cover. Damage will occur to the locking mechanism on the PCV valve.
Remove the PCV valve.

• Disconnect the PCV valve electrical connector.

• Rotate to release and remove the PCV valve.

Positive Crankcase Ventilation (PCV) Valve — 3.0L (4V) Removal and Installation

1. Disconnect the positive crankcase ventilation (PCV) valve tube from the PCV valve

CAUTION: A new PCV valve must be installed if removed from the cam cover. Damage will occur to the locking mechanism on the PCV valve.
Rotate to release and remove the PCV valve.
