I watched the above video before I started working on my 2002 Century. My engine light was/is on and reading the codes I got a P0446. The car has 105,000 miles on it. I went to Auto Zone and bought the Vent valve sol. I checked the valve by using jumper wires and verified the valve closes when 12 volts is applied to it. I did a voltage check on the connector and found no voltage, with the key off, and 12Vs with the key on. I installed it and hooked up the vent hose, and started driving. It did not fix the problem. I uninstalled the vent valve and found that the valve does not close when the key is on. ie I lowered the valve and blew thru it with the key off and on, I was able to pass air thru the valve under both key positions. What am I missing?

Hi , I have the same problem , where exactly are you located in NYC ?

Saved me a huge headache. Thank you

Good evening, great video. Sorry for the question, but do you have a PDF file to study this subject or something explaining about the oscilloscope signal? Normally we have this type of fault here in the workshop and some of them we resolve by directly placing another new part on the ecentric axis sensor, we have also found the same fault with an internal origin in the Dme, we just replaced the item and it was ok, I'm looking for literature to find other ways evaluating the same problem, it would be very helpful to be able to better understand these signs.

I'm praying I can get a reply after seeing this vid is 5 years old. 2010 escalade, random no start, 20 codes about canbus etc if I can get it to scan. Multiple shops, thousands of dollars. I'm an ex mechanic and I need to know what this software is!

please tell me your within the tri state area to include PA

I have a p1450 code it says unable to bleed fuel tank vacuum .. could this also be a reason? Or do you know the solution

For those of you who wonder the hardware needed: 1:16 zoom in for the list of scan tools

Dude, that is a great find! I'm working on a 2012 iQ right now and this video actually helped me out a bit so thank you, man.

Super thank you very much

It’s pretty cool how your explaining this like everyone is a fucking technicians thanks for your help asshole

Experiencing the same problems p0403 and p0443. Thanks for sharing

Will driving the car with this code on hurt the vehicle?

I swear, I think I replaced this like 2 years ago with a Doorman part.. that's crazy

I just accidentally hit a pothole today and this video popped up. Im scared now, how do i know if something messed up?😢

Throttle body carburetor runs the stabilatrac.

Can't tell you how much I miss your vids. 1 of my favs was a Christmas vid with Rocco. I was bedridden that year and you guys cheered me up. What are you doin these days?

My dealer said that it isn’t possible to reprogram a salvaged eps system because the vin numbers won’t match. I’ll take this as proof you can :”)

I have the same issue p0449 when I run passed 65 mPH it kinda lose power will this be the issue Kieth. ? So I’m sorry I’m slow but what part do I need to change ?

My g6 makes a mild popping sound to the left and steering wheel does a slight bump when driving

So the main solenoid was already replaced.. I noticed the wire melting but didn't break like yours, so my next steps would be checking behind the fuse box UH and replacing the solenoid itself

Anybody know some one who could help me in Miami,FL with this situation. Would be appreciated

So how does the a/c pressure trigger the fans? In the ECU?

Bad exspantion valve

Anyone who uses these tools are useless

Nice work detective!

Great video , have the same problem on my 2001 TJ

A good video

I had the same problem in a05 c240 after i did change a bad noise ac compresor that didn’t vacuum the sistem so all I did put ac gauge then i see the pressure in around 500 and supposed to be around 250-300 then I drain some air from the red hose until came down around 250 after I did that the fan starts working normal

So you scanned it but what App are you using to program it ?

I know this Video is 5 years old, but I have to comment. Your diagnostics is incorrect. You had the probe connected on the positive side of the solenoid which will always be at 12V (positive voltage level) and you will not see anything. If you actually saw it drop that would be a major problem. You should of had the scope probe connected to the negative side of the solenoid since you already confirmed that you have positive feed to the solenoid. Second thing is, The solenoid resistance is probably fine. Those circuits are current limiting, hence the fuse.

Hello Sir! Can I get a personal contact to get more information about the C6 BCM reprogramming because in my home no one wanna touch it the car.

Hi again is there any way I can get a wiring diagram thanks.

Man I can't get off the clip!! The metal clip!

Bro so what did you change out. Jesus Christ .

Gracias por compartir tu experiencia

Anyone know of a video to remove and replace this junction box?

I have a problem with my 2016 Yukon. I replaced the steering rack motor and installed a new steering angle sensor. The steering wheel turns smoothly to the left but has a little bit of resistance when turning to the right. The issue occurred when I reset the steering angle module using my launch scan tool. When I start the engine, the steering turns by itself to the left completely and stops. Please help. I need you advice.

How did you fix it friend ?

The exact same Frase whenever I have to go down in one of these babies 😂 Great video BTW

This is the switch for blower ac 1 sends signal to ac request the rest no problem

Hey man, I have a 08 pathfinder. It will crank like it’s trying to start but won’t start. There’s no corrosion or buildup in the radiator cap but after removing the cap and putting it back on, it starts

This is insane, I just replaced the Eccentric sensor almost 2 weeks ago and now it's giving codes 2A31 and 2A32 as well as Valvetronic codes.

mine runs on high with ac off or on never overheats i replaced the whole cooling system was doing it with stock or after market parts

Can you put the name of the tool you use to reprogram the key thanks

amigo puede ayudarme😢 con mi minicooper es que no prende ya lo lleve a tres talleres Y No Saben que es

Sent my computer out to ebay PCM repair 150 $ IT WORKED. Took about a week to return.

Thank you for the video I got a 2008 Chrysler Aspen. I replaced a used ABS but now the two new codes popped out C2022 and C2026. Do you think it can be fixed after initialize the abs?

I had to come back and find this video and say thank you! My fuse was blown! I was about to buy a new vacuum pump! Thanks again

Regarding interpreting data: the so called "valvetronic sensor" is really 2 identical digital magneto-resistive sensors in one module. It's made by NXP and part number is KMA200. You can look up the datasheet. It talks to DME via SPI. It's a good fun to go through the datasheet.. Because it also measures temperature and exposes it together with angle data (it's unclear if DME cares about it though - most likely not). It also has some self-diagnostic features and reports it via error bit/flag. It shouldn't be too hard to write a protocol decoder for Sigrok, so you could read it with one of those cheap USB signal analysers. Not sure if it'd be of any use though - DME reported codes are usually enough to diagnose faults.
