Volkswagen Jetta: P2431 Secondary Air Injection Signal Improbable

In this video I go WAYYYY out of my wheelhouse and try my hands at diagnosing a check engine light on a 2011 VW Jetta. My used car guy dropped it off with the money light on but he reassured me it was gonna be easy. Ends up he was right, but boy oh boy did I remind myself why I don't work on these cars. finding the correct service info is a real pain in the butt! In my opinion any how. -Enjoy!

VW might have issued a warranty recall on this. Used car guy should call dealer. Typically, this part is covered to 120k miles. The part number for the new version of this sensor in the form of a kit with a new sensor and tube is 07K-198-125. Because these sensors have been prone to foreign contamination and fail, VW has issued the above updated kit. Common VDub problem. See here for more: www.import-car.com/tech-tip-2-5l-secondary-air-injection-sensor-codes-due-contamination/ . The CBTA engine is ULEV and CBUA is SULEV (pzev) so difference is the 3rd cat/ o2 sensor for increased cleaner emissions.

Hey Erik when I had to do that secondary sensor along with a map sensor they look almost identical. I think the map sensor had the o-ring and the secondary sensor didn't. U said the guy said he changed the map sensor and he might have got the wrong sensor in it. When I did it I did notice they were different but without knowing about it anybody could make the mistake. Secondary sensor I changed because it was shorted to positive. And yeah after new one is installed it does drop down to 2.6 or 2.5 volts. MAP sensor I changed because it gave me a implausible signal due to the fact the pcv system fails internally and the oil seeps to the pcv hose to the manifold and contaminates the map sensor. Really only fix for that is changed the valve cover with the pcv hose and clean the manifold. With the throttle body u have access to clean the manifold with needle nose pliers and a rag. I say alot of course words too when I work on those volkswagen but u did a fantastic job. Take care

​@@mannys9130 You are welcome to your opinion. Give me an example. To start, I'll give a few examples. The ECM is located in the plenum. Not in the wheel well or against the fender or somewhere stupid like that. The ECM connector is made so that there is a sliding piece that pulls the contacts together and seals it in one go. Every pin lock inside electrical connectors use purple so the user knows what they're dealing with. The battery is easily accessible (again, not in the wheel well or trunk. ALL of the relays are in one location. And lastly, but most subjectively, I like the way the doors sound when they shut. They sound solid and heavy and not shallow or flimsy.

VAG isn't too bad to work on, they just love their special tools, even for diagnostics. A Rosstech VCDS in the cabinet for these special occasions can save a lot of headache, well worth the ~$300. Though sometimes finding the right measuring block for the sensor you're looking for can take a bit of hunting and poking.

[@bertmollar]

I agree. Everyone at my shop hates working on VAG. Being a VW owner for the last 7 years I have gathered a lot of special tools and diag stuff which makes it a breeze and I can almost always beat book time on them unless they are having a really really super weird problem.

[@chancegregory67]

Hello Eric! Hope you had a nice 4th!

[@ouch1011]

I believe the deal is that aftermarket radios or integration kits will sometimes put full battery voltage onto the network, because the OE radio is on one of the networks. If the scan tool attempts to pull the network voltage to ground to communicate when it has full battery voltage on it without a resistor, it will smoke the scan tool. I don't know that it is still a thing, but it was back in the early/mid 2000s. Anyway, I know you've been doing this a while, probably about the same length of time as me, but as someone who has worked in shops that worked on anything that rolled in the door (including Euros, motorhomes, ambulances, etc) and also working for a German car specialist in the past, I want to give you a piece of advice. I totally respect your decision to work on European cars on a very limited basis. They all love special tools and they love to make getting info difficult/expensive (see the next paragraph). My advice is to not be afraid of the technology. The wording may be different but the cars all work the same way. Lots of them use the same parts. EVAP systems on BMWs and VW/Audi (before going to NVLD) was the exact same LDP as Chrysler used, with all the same common failures. Now a days, most domestic cars are built the same as German cars. They all pretty much use Bosch GDI. Many are turbocharged used turbos from the same suppliers the Germans use (Borg Warner) so the systems are designed the same way. Pretty much all domestic cars now use the same network communications layouts that Germans have been using for nearly a decade. So, if you are afraid of "German" technology or the way Germans build a car, you aren't going to be happy working on new Domestic cars either. Regarding the lack of info availability for pretty much any German car, they are exploiting a legal loophole. The right to repair act requires them to make repair information available to independent shops for a "reasonable" price. Rather than doing that by making their service manuals available to aftermarket publishers (alldata, motor, identifix, etc.) they make it part of their OE scan tool and make the scan tool available for use with a J2534 device. You subscribe to their service, download the software, scan the codes and it gives you diag info for those codes. Its called "Guided Fault Finding" and it is absolutely ridiculous because it has you testing the car the same way that old printed flow charts used to, complete with the old "substitute a known good part" line. It's another way the German's make their cars intentionally harder to work on for independents.

[@JPilot2]

G'day, Mr. O! I enjoyed the video! As you may know, when the PCM detects voltage or resistance that is outside the normal expected value range within the secondary air injection system air flow/pressure sensor circuit bank 1, code 'P2431' will be set and the check engine light may be illuminated. I was going to suggest... You could research the Technical Service Bulletins (TSB's) for the specific vehicle by year, model and power plant. In some circumstances, (as you know) this can save a lot of time in the long run by pointing you in the right direction. Based on the specific vehicle, this circuit may incorporate several components including "the secondary air injection pump, check valve, pressure sensor, air control valve and the PCM." Performing a thorough visual inspection to check the associated wiring for obvious defects such as scraping, rubbing, bare wires, or burn spots. Next is to check the connectors and connections for security, corrosion and damaged pins. Of course, this process would include all wiring connectors and connections to all components including the PCM. Confirm every component incorporated within the circuit which may include a fuse or a fuse-able link. The check valve should be tested to ensure that the airflow is in one direction only. Ice in the secondary air injection pump during extremely cold weather conditions is an indication of a defective one-way check valve allowing condensation from the exhaust to enter the pump. The reference voltage and the acceptable range based on the vehicle and the circuit configuration. This process identifies the absence of a power source or ground, continuity testing may be required to check the integrity of the wiring, connectors and other components. Continuity tests can be performed with the power removed from the circuit and the normal readings for wiring and connections should be 0 ohms of resistance. Resistance or no continuity is an indication of faulty wiring that is open, shorted or corroded and should be repaired or replaced. Common Mistake: Replacing the secondary air injection pump when a faulty one-way check valve or defective wiring is causing this code to be set by the PCM. Hopefully, the information has been helpful to point you in the right direction to correct the problem with the secondary air injection system air flow/pressure sensor circuit bank 1 fault code. Thank you! Cheers!

[@Graham_Wideman]

Well, regarding TSBs, 7:55. Regarding the rest of your suggestions, sure, these are all things someone with no other direction and a lot of spare time could do. But Eric is cleverly relentless in narrowing down his path and avoiding unnecessary detours (except as it adds to the informative nature of the video). In this case he combated lack of familiarity by applying eminently sensible reasoning to suspect that a sensor that runs on 5V would probably be designed to output near mid-supply voltage as a default (atmospheric pressure) value, and seeing the sensor did not, it was suspect, especially as that defect matches the reported code. And he was right about the voltage. So we'll see what happens in part 2, but I suspect his process turns out to have been pretty efficient.

Eric O you have more patients then I. Loved it when you gave the hose the one finger salute. I would have made the video R rated very quickly with the words coming out of my mouth. You would heard one long BEEP!

Welcome to our world Eric.

Good job old man in wanting to learn new things! ;)

You should invest in "special" plier for those springy hose clamps. Ther is two verisions one on a wire (for tight spaces) and one "regular" plier. Have done like you and used the nearset plier and nerly got pinched several times.

as a mechanic myself I like the way you diagnose people always think the scan tool tells you what to replace but we know from experience that it is sometimes right unless you diagnose properly you can end up putting on a lot of expensive parts for no reason :) also did you look how many screws you have to undo to check the air filter I think from memory there's 8 or 9 :)

Good luck Etik good thing there was more service data to show you all its giggly bits when you said it's a 5 cylinder I almost spit out my coffee and laughed yeah they added a cylender to pump in more air. It's all your bud keep your hand sanitizer handy and have at it

Euros.. yay! Then you have to replace a radiator and realise the whole nose clip has to come off but only after every hidden clasp has been found and the secret process to release them unbroken was never thought of! Give me Lada lol

I worked on VW's for 34 years. A friend put it best - Over engineered, Under implemented.

Back in college when I was a student, a professor for differential calculus was talking about how the Germans calculated things out a bit further when designing things. You know that one extra decimal point. It kind of brings some insight as to how they think.
