Diagnosing Error Codes
By now you know The Gadgetman Groove causes a good amount of changes to a vehicle. Changes that have been known, if you try to move too quickly, to cause the ECU to go bonkers. After applying The Groove, I have seen error codes for the ABS (Anti-Lock Braking System), Charging System and (God bless the programmers) even for Suspension System Errors!
Usually, if you start the conditioning process all over, and take your time this time, the errors won’t be repeated. Since the process clears all existing codes, it also gives the computer time to think about what’s happened and to make better decisions.
But you just have to take your time and let the process happen just as it’s outlined. In the event you do get a recurring error code, then you probably messed something up. Like leaving a hose off somewhere or not connecting all the sensors. The diagnostic codes will help point you in the right direction.
http://www.obd-codes.com/ is an excellent resource for the diverse ways error codes can be triggered. Register and use it. You’ll be glad you did!
Now, to be fair, the codes I listed were really caused by doing too much at once with an engine and not allowing the computer to properly adjust, which is one of the many reasons why I advise my Gadgetmen to “Make your changes small and incremental.” Make a SINGLE change, let the computer adjust and tune itself. Then and ONLY then, make your second change.
The proper way to go about this process is to first realize it is very much a process. That means it’s not a one-shot solution to the criminal actions of the car manufacturers (to benefit the oil companies and the people investing in them) as they continue stealing billions of dollars every single day from the American People. Maybe we should file charges against them for “Theft by Unlawful Taking.”
Shell Oil broke the 1,000 mile per gallon barrier in the late 70’s.(Watch the movie “Gashole” for a real education)So why is it now, pound for pound, mile for mile, with the most fuel efficient engines ever devised, our average fuel consumption is HIGHER NOW THAN IT WAS IN THE 70’s?
I digress. Our job as Gadgetmen is difficult. We must overcome EVERY aspect of their control systems if we are to get every ounce of power out of our fuel. If we do it correctly, then the ECU won’t know what happened and we’ll be cruising at 100+ on every vehicle in the nation. Unfortunately, We, the People have been programmed very well. We have been programmed to trust the Automotive Service Industry that have been trained by the establishment to trust the computer and whatever it says.
But the computer is a STOOPID beast. It only knows what it’s been told. What we’re doing is telling it that it’s okay to get better mileage. It has been programmed to ensure a certain amount of waste in our vehicles. It is the WASTE we want to eliminate. It is the waste fuel, the stuff the engineers write off as a necessary evil, that we are gaining power from with The Gadgetman Groove.
On to the diagnostics.
The most common error codes I see are lean codes. Lean codes indicate too much Oxygen in the exhaust and is almost always caused by vacuum leaks. When you see this, know there is a service issue, usually due to poor maintenance. One loose hose won’t bother the wasteful system, but once The Groove is applied, it will cause the leaks to draw more air, generating this error code.
Vacuum leaks can occur anywhere there is vacuum. The latest surprise I had was in the 5.7L Dodge Ram. It seems on the underside of the intake manifold there is a pan and a pan gasket that routinely blows. (I found this one showing the blow-by gas in the breather hose. I told him to put his finger over the hose to feel the hot gas coming out. It was SUCKING! Boy, did I feel like a turd!)
Check all your hoses. Get a hand-held vacuum pump and learn to use it. Don’t short yourself on this vital tool! GET ONE.
I recommend also performing a simple test on the brake booster, for this is one of the easiest to overlook, and the most difficult to pump down test. Not only is it hard to find, it is quite expensive for the client to have repaired and I will never like giving a client that kind of bad news.
A simple test for the booster assembly is to start the engine and let it idle. Now, while you’re in the driver’s seat, just watch the tachomoter (or listen to the engine if you don’t have one) and step down on the brake pedal. If you see a change in the idle-up OR down-then you have a problem there.
But it could just be the one-way valve, too, so replace that first as it’s the cheapest solution and is so easy to do.
Anyway, here’s what you do when you get error codes.
- Pull the codes. The quicker you pull the code, the closer you will be to finding the solution, for many times one error can cause other errors. DON’T TRUST THE COMPUTER!!! (If you don’t have a code reader, then go to your local parts house and ask them to do it for you.)
- With the codes in hand you can start your search.
- POST ON THE FORUMS! It is only by sharing our problems that we find solutions. Sharing our solutions makes us all grow stronger.
Lean Codes equal a vacuum leak.
End of discussion.
No questions asked.
If you have found a code after a system has been running for a while indicating Cat below efficiency or below temp, that is actually a GOOD sign. (I keep an OBD reader in the seat of my Expedition, because this will cause my mileage to drop from 24 to 7 if I don’t clear it!)
Just think: What keeps the Catalytic Converter hot? Where does that heat come from?
Burning Fuel! So, if the cat temp drops, remember it is supposed to do that! In fact, if the cat temp does NOT drop, then you haven’t done something right. Go back and do it again. We are testing a new solution for this dastardly system for the ECU is using the cat to create more waste. If it doesn’t have enough work to do, it will force what they call ‘Over-Fueling’.
I call it “THEFT”.
We are creating engines that run vastly cleaner, vastly more powerful and vastly more efficient. It is the wasteful systems that keeps us slaves to petrochemical corporations.
The people who designed these systems are criminals. In fact, our entire world is being run by criminals, whether it be the Government, the Corporations or the Religious Organizations.
I have decided to take my power back and to help as many as I can to do the same. It is not an easy path, to be sure, but somebody’s got to make the changes possible to lead us to a new era of freedom.
Welcome to the revolution.
