What are the steps for replacement of the aircondition vaporizer?

You must complete a OBD2 drive cycle, unless you do the kind of driving that satisfies the computer testing you can drive for a year. Go here for the test and how you need to drive to complete the drive cycle.

1 Ensure that fuel filler cap is fully closed (minimum three clicks).

2 Fuel level > 30% and < 85%.

3 Using WDS scanner perform ECM DTC Clear (even if no DTCs are flagged).

4 Drive vehicle for a minimum of 2 minutes, and until engine is at normal operating temperature.

5 Using WDS, ensure that the EVAP Canister Purge Valve is operating by observing "PURGE VAPOR MANAGEMENT VALVE - DUTY CYCLE". If the valve is not

active, ECM adaptions have not been learned. Conduct a "green ECM" Drive Cycle as described in Technical Service Bulletin.

6 Drive vehicle to the road where the EVAP System Drive Cycle will be conducted. Stop vehicle and switch OFF the ignition. Leave ignition OFF for 30 seconds,

then restart the engine.

7 Accelerate briskly to 80 km/h (50 mph) ensuring that the engine speed reaches a minimum of 3500 rpm for a minimum of 5 seconds.

8 (0.040 inch EVAP Test) View WDS "PURGE VAPOR MANAGEMENT VALVE - DUTY CYCLE", "CANISTER CLOSE VALVE - VAPOR RECOVERY SYSTEM", and

FUEL TANK PRESSURE - VAPOR RECOVERY SYSTEM". Avoiding high engine loads, drive the vehicle steadily between 65 km/h (40 mph) and 100 km/h (60

mph). Avoid driving conditions that will produce excessive fuel movement. WDS should give an indication that the test is active (it may take up to 30 minutes

before the test will initialize). When the test has initialized (EVAP Canister Close Valve CLOSED), it will take approximately 90 seconds for the test to complete.

9 (0.020 inch EVAP Test) Continue driving vehicle as explained in Step 8 for an additional 10 minutes.

10 Gently coast the vehicle to a stop. Allow the engine to idle for 2 minutes and view WDS "PURGE VAPOR MANAGEMENT VALVE - DUTY CYCLE", "CANISTER

CLOSE VALVE - VAPOR RECOVERY SYSTEM", and FUEL TANK PRESSURE - VAPOR RECOVERY SYSTEM". WDS should give an indication that the test is

active. When the test has initialized (EVAP Canister Close Valve CLOSED), it will take approximately 90 seconds for the test to complete.

11 If the 0.020 inch EVAP Test is not activated, the purge system vapor concentration may be too great. To reduce the vapor concentration proceed as follows:

12 Drive the vehicle for an additional 30 minutes avoiding driving conditions that will produce excessive fuel movement. Repeat Step 10. If the 0.020 inch EVAP

Test is still not activated, repeat the Drive Cycle from Step 6.
13 Using WDS, check for and clear flagged DTCs

This is a step by step elimination process, check you tube for diagnostics.

Help trouble locating vapor canister vent valve on 2006 Lincoln Navigator 5.4L

Your Orifice tube is probley clogged and needs replaced i wouldnt recomend this be done by someone not trianed to do tho also with new laws regarding freon unless you have acess to a reclaimer it is illegal to do becuase entire sytem has to be drained to get to tube

The vent from the tank,to the fuel fill(small hose)is stopped up.

You Have a HEATER CORE Leaking, This Requires Replacment Of The HEATER CORE, And Untill This Repair, I Do NOT RECOMEND DRIVING the Vehicle Due to the Chance of OVERHEATING the ENGINE. For Detailed Info on this Repair Email me at rejakwilson @ aol.com I Will Be Happy to Send you A File With ALL the Info you Need. And Please dont forget to RATE me here @ FixYa.com.

Good day
P0450 is Evaporate emission system pressure sensor/switch
the cause could be
1. short or open in the vapor pressure sensor circuit
2.vapour pressure sensor
3. ECM

You can test with the following
you can access the ECM behind the glove box. turn ignition on,backprobe the ECM connector, on A/T models, measure voltage between terminals #1 (green/black wire) and #22 (brown/black wire) at the ECM E6 connector. on M/T models measure the voltage between terminals #1 (green/black wire) and #9 (brown/black wire) at ECM E6. if voltage is 4.5 - 5.5 volts, go to the next step. If the voltage is not 4.5 - 5.5 volts, replace ECM and retest.
2. back-probe ECM connector on A/T models measure voltage between terminals #15 (red/blue wire) and #22 (brown/black wire) at ECM E6. on M/T models measure voltage between terminals #4 (red/blue wire) at ECM E5 and connector #9 (brown/black wire) at ECM E6 connector. on all models disconnect the vacuum hose from the vapor pressure sensor. sensor is located near the brake master cylinder. connect a vacuum pump to sensor. if voltage is 2.9-3.7 volts without vacuum applied and 1.3-2.1 volts with .59 in.Hg (2kpa) vacuum applied. replace ECM and retest if voltage is not as specified go to next step.
3. check for open r short circuit in the wiring harness between vapor pressure sensor and ECM. repair wiring as necessary. if wiring harness is okay replace the vapor pressure sensor.

Hope this helps

Cheers

Hi, this will help you achieve your goal.


Step 1

Park the vehicle in a safe place and make sure there is enough room around the back of the vehicle for you to work and move tools around.

Step 2

Start the engine and let it idle while you relieve the fuel system pressure by removing the fuel pump fuse or relay from the fuse box. Wait a few seconds for the engine to stall, turn the ignition key off and replace the relay or fuse.

Step 3

Raise the back of your car using a floor jack and support it safely on jack stands.

Step 4

Disconnect the fuel tank filler pipe and the fuel pump connector located above the cross member underneath the vehicle.

Step 5

Disconnect the vapor tube from the tee connector on the right side of the car-passenger side-and the vapor line from the canister tube.

Step 6

Support the fuel tank with a jack and remove the nuts from the holding strap using a wrench or ratchet and socket. Move the strap away and lower the fuel tank. Discard the fuel tank mounting studs.

Step 7

Unplug the pressure transducer electrical connector located on the top rear corner of the fuel tank.

Step 8

Clean the area around the fuel pump mounting flange and remove the flange mounting bolts in a crisscross pattern.

Step 9

Lift the fuel pump assembly off the tank. Replace the new fuel pump in the assembly and install the assembly in the tank. Install the flange screws and torque to 89 inch lbs. (10Nm) using a crisscross pattern.

Step 10

Raise the fuel tank to its mounting position, install the strap using new mounting studs and torque the nuts to 26 foot lbs. (35 Nm).

Step 11

Connect the fuel pressure transducer electrical connector, vapor tube to the tee connector, vapor line to the canister tube, fuel tank filler pipe and fuel pump electrical connector.

Step 12

Lower the vehicle, start the engine and check for leaks.

Never heard of aircondition filters on an automobile.There is an air filter that filters air going into air intake.It has no effect on the a/c.
