2010 Volkswagen Jetta 2.5L- P2433 Secondary Air Pressure Sensor Signal Short to Plus

working on a 2010 vw jetta, customer complaint is a check engine light, the veh has 1 trouble code stored P2433 Secondary air pressure sensor signal short to plus, this veh uses a pressure sensor to monitor secondary air flow it is a 3-wire sensor 5v, ground, and signal, very similar to a map sensor, I hope you enjoy this video and thanks for watching.

As I recall, my 2009 2.5 Jetta had an extended warranty on this part. I got the same code and it was replaced under warranty at 110K. Good to see someone doing VW diagnosis, you will never go broke working on VWs...

[@TheRealJimParker]

This was very thorough and super helpful me to diagnose my 2010. Thank you for taking hte time to share this.

[@bobt250]

Thank you so much for taking the time to make this video. I found my car to have the exact same voltage measurement at the sensor. Don't know what I would have done without your instruction.

[@pinpointautomotiverepair1592]

I just did one of these the other day, same year, model and engine package. Must be a common failure! Great work man.

[@mbarry9737]

I like the tip about changing fault codes from current to intermittent by unplugging the sensor. Haven't tried that before but will in the future!

[@gbowne1]

"Caution - Do not replace components based on fault codes alone." Good advice Snapon. Great diag. here Thanks Tom.. Seeing a intermittent and a high voltage on a pressure sensor.

[@rrmech11]

Tommy I enjoyed the non communication video with Paul. Keep up the great videos

[@ibringyoutoruin]

Great logic with the scan tool by setting dtcs ensuring circuit integrity and leading torwards faulty shorted sensor. 5stars my friend

[@haywardsautomotive6156]

Nice diagnosis & repair Tom!

[@xerxes456]

Like other people I thank you for showing Euro cars there is not many out there what I now of, Good work Tom

[@DylanRabier]

You really sound like ScannerDanner. Thx Tom nice video 👍

[@Pablo_Automotive]

Thanks for share Tom, regards from Spain =)

[@4stringbazooka]

Great video. I'm glad that I found this channel from your "crossover" with ScannerDanner. I was running out of case studies to watch and learn from with out getting Danner premium. Also, huge fan of learn about vehicles that my shop normally just turns away. You're making me realize that the same diagnostic steps I take with every vehicle can/will work with "Euro trash". Thank you for the share.

[@NewLevelAuto]

4stringbazooka keep in mind that using erWin is the key to wiring diagram success on these cars.

[@ScannerDanner]

ah dammit, I should have never told you about Tommy :-)

[@NewLevelAuto]

ScannerDanner 😎

[@4stringbazooka]

I will keep that in mind. Thank you.

[@4stringbazooka]

Hah! Don't worry I am still thinking/saving up for your book and your premium channel. All of your case studies and strategies I've watched over the years, have really helped me become the diagnostic tech I am today. So thank you for all of that you've shared on KZbin and your forums over the years and thank you for sharing your "boy" Tommy off on your channel. I'm kind of a huge fan of case studies.

[@sergiobayardo5127]

love your videos, miss you posting new stuff, hope is all good with you

[@PositiveLeadDiagnostics]

All is good. Just trying to find time

[@conrad1468]

Great video. Very informative.

[@baxrok2.]

Nice job. Thanks!

[@ThePillsburry]

Did I see dans laptop in video I recognised screen damage great video

[@blockbertus]

Good video, Tom. In case some people don't know or are wondering, "G" + number means "Geber" which translates to sensor. :)

[@jgeorges3061]

good video and info tom, thanks for sharing cheeeeeers.

[@THREESHOTBANDIT]

Atta boy Tommy! Keep up the good work! Really learning a lot from your videos!

[@chadcohoon8867]

awesome job my man

[@kamrynstarrett1834]

Where can one find this part? I use rock auto for my parts and I can’t locate it?

[@kaffetrakter4174]

Isnt 1-5V and 0-5V normal ranges on sensor output? But i agree, 4,5V is high when there is "nothing" in the tube/engine off.

[@billyr9840]

Nice easy one Tommy !

[@malisa696]

great video. Maybe it is not a bad idea to give some short explanation about the purpose of the secondary air pressure on engine for getting a better view of the problem.

[@EXOVCDS]

Nice one! It's sad that snap-on is lacking a lot of info... no data pids for certain VW & Audi vehicles, even though the cars are 6 to 13 years old. I feel even more sad for the techs who update their snap-on scanners more than once per year at a cost of $800+ each time. You'd think that after 6 to 13 years, that snap-on would start filling the gaps!

[@aleksandrzinkevics1253]

do u pay year subscription on Elsa or go there when u need and pay hourly charge?

[@5226624n]

Hi tom , may ask you what program are you using for uro cars ? Thanks in advance

[@ianchot74]

Hi Tom. I have 2010 Audi Q5 and have p2432. when i deleted the code it reapers immediately after the second start of the car . i am pretty positive it is the pressure sensor and already purchased it to replace but what worries me is that in your video the code reapers even you changed the sensor. could you please update how did you get rid of the code p2432. thank you in advance and thank you for the great video.

[@gregorybrito5169]

Well done!! I'm from Brazil and I have almost the same problem with a 09" Jetta 2.5. Do you have the code (the original Volkswagen part for code) of that air hose/sensor? If you do can you send It to me? Thanks a lot!!

[@nicknicu1787]

Well done Tom! I think I've told you this before,but there aren't many channels doing Euro Trash. I personally like them! I love a good challenge! Lol! And it pays well if you know what you are doing. Euro trash for the win brother! Thanks for the videos!

[@marcuswhite1403]

I'm working on a 2012 beetle 2.5 that's throwing up that code. Looks like it has the updated Secondary air pressure sensor. How much did you pay for the updated one?

[@ScannerDanner]

You think the HEX-NET would have had a PID for the air pump system? Or what about Milo? (Milo and Otis haha)

[@NewLevelAuto]

ScannerDanner Hex net would've been perfect for this job

[@ScannerDanner]

cool man. Thank Keith

[@syednurnaim4800]

Thank y

[@syednurnaim4800]

Thank you brothers paul denn you education very good work🧐🥳happy new year 2021🇺🇸to 🇲🇾

[@thecommenter7201]

Thank you for the video. But please next time start the engine before you end the video. Watching real life symptoms is better than just a P2433.

[@williamakonu-atta]

I saw you idle was at 1400-1500RPM. Was it due to the sensor?

[@ssrbob]

What video camera are you using?

[@mecanicav3220]

Super top.... conseguir ver o sensor, obrigado...

[@crisdiez7077]

I have no codes but my sec air monitor just won’t set and I don’t know what to do I already drove the damn thing for more than 200 miles in one single trip... and been driving around town and still nothing 🤷‍♂️

[@neondiamondsaquaberry17]

So P0491 insufficient flow bank 1 is most likely the air pump itself right ? I have an 09 Jetta 2.5 , can you help me please with any way to test the parts ? Could it be the Kombi valve stuck in closed position or I just need to replace the pump only

[@PositiveLeadDiagnostics]

It could be a few different things. Best way to check for leaks is energizing the pump and soapy water. If it’s a big leak you will hear it

[@neondiamondsaquaberry17]

I had a crack in the hose right before it connects to the combination valve , a little duct tape and it’s fine now , no more light .. I’ll repair the hose with silicone tube when I get a chance, cheapest I’m finding that hose online is 120$, way over priced for a 3 foot plastic hose

[@PositiveLeadDiagnostics]

Good find. Those plastic lines get cracks all the time

[@tedmartinez9129]

how much did that sencor apparatus cost

[@cubesix5]

Could this fix the code p2437?

[@andrewbecker4443]

What’s the part number?

[@hasankhalid1436]

Good

[@brownboybrownboy749]

Thanks bro love your video!!! How much cost the wire sensor!!

[@CHIBA280CRV]

👍🏻

[@jetplanzs8242]

Does the map sensor look just like air sensor? Because im trying to find out I think the map is under the throttle body and the secondary is right above we’re your sensor is at I got a 2.5l 5cyl

[@PositiveLeadDiagnostics]

Yes they look the same. Map is located under the throttle body

[@cubesix5]

I am trying to find the location to this part all i can find is the map sensor on my 2015 gmc terrain

[@dcartellone2659]

So basically you replaced the sensor...and all is fine..got same code. What size torx bit to remove it.wouldve been nice to see how to remove it and install it.

[@mariopatlan9595]

My 2011 VW Jetta SE has this same code and it tends to stall when starting up or when at low velocities. Could this secondary pressure sensor be responsible for the stalling?

[@PositiveLeadDiagnostics]

Most likely it is not the sai pressure sensor. However I have only seen it once where the sai sensor was shorted and pulling down the 5 volt reference. For stalling issues. The crank position sensor is very common on 2.5 engines

[@mariopatlan9595]

Positive Lead Diagnostics You were right. Replacing the crank position sensor seems to have solved the stalling issue

[@PositiveLeadDiagnostics]

Nice!

[@andreasandreasv7259]

Help with this diagnose,1 engine speed sensor (G28) 2 oxygen hambda sensor B1 S1 heating circuit 3 malfunction knock sensing monitoring

[@andreasandreasv7259]

But the speed sensor I replace it but still the EPC light is appearing

[@alamoja]

I'm having this same problem currently. What is the name of part? I am trying to pass my emission test. Thanks 🙏🏾 Ps : I have a 2012 Volkswagen JettaSE 2.0

[@PositiveLeadDiagnostics]

Secondary air pressure sensor

[@alamoja]

Positive Lead Diagnostics thank u

[@A55Hol3_Actual]

Yes it is like a MAP sensor. It is a MAF sensor. I can't find where mine is supposed to plug into from the sensor. Eeeek

Where are you guys?
