I received a letter letting me know our '22 Camry has a recall to inspect and possibly replace the crankcase case vent. Has anybody had this recall performed on your Camry? If so, what was involved in inspecting and replacing the CCV? It is recall campaign 22TC05. I can't find any information online about this recall.

Have you tried to search on the NHTSA site? type in your VIN# and see what comes up. I'm sure it's a simple fix.

Yes, and nothing there. I talked to my dealer yesterday and they know about the recall. They just aren't sure about the procedure, etc. They said they have yet to carry out the recall on a vehicle.

I appreciate your link. What I'm interested in is how would a tech determine if a CCV is defective or not. More importantly, what's the extent of the surgery on the engine? It looks as though the intake has to be removed in order to get to the CCV. I'm always uncomfortable with major components being removed from an engine and then reinstalled.

@Oliver Springs

look at the second link i provided. it's the technical instructions including how the techs will inspect and determine if it needs to be replaced.

That helped. Thank you, fungabriel.

So the links say the repair is going to take 4 1/2 hours with removal of intake manifold to get to the EGR valve. The steps show this will be a major pain inn the ass for a future DIY EGR repair or cleaning of deposits from the system.

Indeed..
That`s a pretty involved repair based on the number of gaskets to be replaced due to dismantling...
Basically they have to remove everything in front of the engine!

Exactly!

More to it:
This is campaign No. 22TC05 - C meaning : Special Service Campaign

Hi fungabriel. This is a good candidate for the sticky:

And that concerns me. Perhaps I put too much thought into these things. However, that's because I see incompetence in so many places these days. There are some steps to this test and fix that require attention to detail and I hope the techs pay attention to what they're doing. Also, I noticed that part of the test involves a balloon. That's pretty low-tech. I would've thought that Toyota and its suppliers would have had more quality baked in to their components by now.

@memexe

Yeah, i was debating on that since it's not a safety recall, its a special service campaign. If i read it correctly, it doesn't affect the relibility of the engine, it just releases a little bit of unnecessary emissions. Though i can add it to the recall thread regardless.

If it works well and is cheap to operate, why not.
Imagine a precise tool that has to be calibrated to measure that pressure when all that`s needed is to see if the pressure is positive or negative...

Perhaps. You would think that a manufacturer (Toyota) whose worldwide sales are up 19% could afford a higher tech tool to test vacuum than a balloon. I owned a new 1988 GMC 1500 that had HVAC actuator issues. A service manager said whenever the actuator acts up just hit the bottom of the dash and perhaps it will make it operate correctly. That was a low-tech solution and it was a frustrating thing to deal with.

Super high-tech green and red balloons were used for a more dramatic effect.... Balloon or plastic bag. Anyone could easily perform the test.


VI. INSPECT VACUUM PRESSURE OF NO. 2 PCV HOSE

1. Disconnect No. 2 PCV Hose a. Use Squeezing motion on clip handles to slide clip up No. 2 PCV hose and remove hose from air cleaner hose.

2. Install Balloon for Testing

a. Use tape (painters tape, masking tape, electrical tape, etc.) to seal port on air cleaner hose. NOTE: It is important that tape seals the port completely. A port that allows un metered air to enter the engine may set a malfunction indicator light (MIL).

b. Attach a balloon over No. 2 PCV hose. Use clip to secure balloon tightly over No. 2 PCV hose. If a balloon is not available, a small plastic bag can be used in place of a balloon.

NOTE: It is important that the balloon or plastic bag seals tightly around No. 2 PCV hose. If there is not a tight seal around the hose, the inspection will not be performed correctly.

3. Vacuum Pressure Test – Gasoline and Hybrid Engines

a. Start the vehicles engine and allow the vehicle to idle for 15-20 seconds.

Do NOT allow the engine to idle for more than 20 seconds. Damage will occur to the engine oil seals.

Note: For hybrid vehicles, engines can be started by depressing the accelerator pedal quickly 2-3 times or using inspection mode. Refer to TIS for instructions on General / INTRODUCTION / REPAIR INSTRUCTION / INSPECTION MODE PROCEDURE

b. Stop the vehicles engine after 15-20 seconds of idle and observe the condition of the balloon.

c. Use the inspection results chart below (page 8) to determine next steps.

d. Remove tape from air cleaner port previously taped.

e. Remove the balloon assembly or bag from PCV hose NO. 2 and reintall hose on air cleaner port. Slide spring clip over hose port connection.

I actually thought about doing this test myself. A couple of days ago fungabriel posted this very link to the procedure. I may still do this test. What has kept me from doing it thus far is the double strain on the gaskets and seals. Putting them through a test on my part (should it fail) and then one from the dealership (so they can fix it) would be a double strain. Also, "Do NOT allow the engine to idle for more than 20 seconds. Damage will occur to the engine oil seals" stands out in my mind.

I hope everybody had a good Thanksgiving.
