MAF enhancer installed on wrong wire - engine codes

I tried installing an MAF enhancer to compliment an HHO generator I had installed.

I am having difficulty determining the correct signal wire. I tapped into the wrong one, and now I have error codes. ARS, Engine, and sometimes a blinking Glow Plug.

Coming out of the MAF sensor are 4 wires. Black, Green, Red, and a larger yellow wire. I tapped into the yellow and tested. Oops, wrong wire - what a dope.

The red wire gives a solid 2.1 volts, the green will fluctuate between .1 and .6 (This may be the right one). However there is no voltage on the black, the yellow will give a quick reading then just drop to zero, but niether black or yellow seem to work as a ground when tested with the red or the green. However, the green wire does a fine job working with the red. Also I noticed that when you test the red with the engine running it revs the engine up a little. Thats wierd.

Current symptoms: Engine runs louder and with less power. I don't know if I just ruined the ECU or the Turbo. But my guess is that the turbo is out.

What now?

    MAF sensor located right at the air filter compartment. Wire plug consists of the 4 wires, black, Green, Red and a larger yellow.



    After disconecting the enhancer the car still runs quite loud.



    I have not gone to auto zone yet to download the codes. But tht lights coming on are the ARS (which is a circle with a triangle inside and an ! inside the triangle), engine, and the glow plug light is flashing.

  • venutt Sep 20, 2008

    yes the enhancer is just a resistor.

  • venutt Sep 20, 2008

    Is there a way for me to reset the ECU/ECM?

  • venutt Sep 20, 2008

    I have disconnected the enhancer and repaired the wired I tapped into, so everything should be as it was. I also disconnected the negative battery cable for about 30 minutes.

    Still the same. loud and less power.

  • venutt Sep 21, 2008

    Your advice on the fuse was right on. There was a 10 amp fuse blown. Replaced. Now car runs normal and all lights are out - except for the engine light. I will check other fuses and relays tomorrow in daylight.

    One question. The red is the send signal so that it the wire I need to add the resistor to. But why is there a return signal? I also found out today that the car does have and oxygen sensor. Do you think and extender ring will aid in better gas mileage? Thanks for the help.

    when I loosen the red wire on the 4 terminals on top of the battery it seams the fan cuts in but when I tighten it up no wipers,head lights,heater motor,
    don't know what the problem is. i DID REPLACE THE RED WIRE THE OLD ONE HAD A BURN MARK

The green is the signal wire, black is what we call the ground reference, 2.1 volt wire is reference voltage, but that is very low, shout be around 4.5 volts, you need to verify that voltage with the MAF disconnected check between the ground and red.

The big yellow wire is your current feed. the black is your ground, the red is the send signal and the green is the return signal this should help. if you did spike the ecm then you might have just blown the 5amp fuse for it. i would check all your relay/fuses to make sure they are good as well. please rate this solution..thanks keep me posted

What does your MAF consist of ?
what did you get for instrusction?
is it just a resistor?
what are your troublecodes?
does the engine run fine without the enhancer installed?

  • Anonymous Sep 20, 2008

    doubble check you air intake hoses make sure you not leaking any turbo boost.
    when you say loud. what kind of luod sound? like pressurized air?

    It would be nice if you could let us know how your hho conversion does. all science is negitive on this working . yes your gas or diesel engine can run on hydrogen but However, what you can't do is run a car on water without energy inputs greater
    than you get from splitting the water. In simple terms, let's say you split
    water to create 10 BTUs of hydrogen. You can then use that to burn in the car,
    or to operate a fuel cell. When you burn the hydrogen, it reacts with oxygen to
    again form water. But if you want to take the water and turn it back into
    hydrogen, it will always take more than the 10 BTUs that you released in the
    first place.

    So let's say it takes 12 BTUs of input to produce 10 BTUs
    of hydrogen from water. What's wrong with that? Well, why wouldn't you just use
    those 12 BTUs directly, instead of going through the step of cracking the water?
    This would be sort of like using gasoline in your car to produce steam to drive
    a steam engine that actually runs the car. But it's a lot more efficient to cut
    out the middleman and use the gasoline directly.
    i havent seen it work yet. i seen alot of claims but no proof.
    and everyone that has had proof have been discredited.
    later paul

My HHO generator draws too many amps, how do i get the amps down?

1st thing to check is the electrolyte: Use white vinegar, NOT baking soda or lye. Use a minimum of 12 ga wire on all connections, and power the generator through a relay using a 30A fuse to feed a 40A relay.Install a Tap-a-line connector from the radio circuit of the fuse panel to the toggle switch, then run a 14ga wire from the toggle switch to the relay. Doing this ensures that the generator is energized ON LY when the ignition switch is turned on. The 12ga feed wire to the relay should connect directly to the positive terminal on the battery. The 14ga wire from the switch is used only to activate the relay. This way the relay carries the amperage to the generator, and it does not pass through the switch. If the amperage is still too high, use less vinegar and use more steam distilled water to lessen the concentration, therefore lowering the amperage draw. All the parts required for this hook-up can be obtained at AutoZone, Oreilly's, etc. Good luck.

Got some problems with my hho

The HHO generator uses low DC voltage to produce Hydrogen and Oxygen from water.

Fresh water isn't the best conductor of electricity so an electrolyte of some sort is usually added to the water.

A safety tip: This was probably included with your unit, but it doesn't hurt to cover it again.
  • Wear safety glasses, good ones.
  • Dont smoke or have any ignition source while checking the unit. HHO is produced at the optimum ratio for combustion, and by that I mean COMBUSTION. This is the same fuel in the same ratio in that big orange tank the space shuttle rides on. The slightest leak can be dangerous. Be aware of this. Ok?
A side effect of these units is they produce heat. The water gets pretty hot, not boiling, but hot. That would be a way to see if its working.

You haven't described the unit, volume of water and electrolyte used. That would be helpful.

As a rule, if the plates are covered in water, if the electrolyte has been introduced, if it has power then it's working and you won't notice any difference at all.

Unless the unit you got is the super deluxe multi-cell model, the volume of HHO produced per minute is only a small percentage of what the engine is sucking in. It's not going to supercharge your engine. It will however enhance the combustion of the gasoline, making it burn more efficiently while adding some combustion of its own.

Hopefully you kept track of your mileage before instrallation. Keep keeping track of your mileage and compare notes. That's when you'll notice the difference.

That difference will depend on the volume of HHO produced. That depends on the electrolytic agent, volume and temperature of the water.

I hope this helped somewhat
Mike

HHO GENERATOR

Please do some research before bothering with this bogus junk.  I am familiar with its generation and you cannot fit a generator under any hood that will produce enough gas to change your engine characteristics.
Take some time and look at the EPA's results with any of the claimed results for various gadgets:
EPA Fuel Saver reports  
Also, if you had a product to sell, wouldn't you be tempted to plant favorable 'test reports' all over the Internet?

HHO generator wiring

the hho generator power and ground does not go to the maf sensor. what you need is a maf /map regulator, but it has no connection with the generator. it is just helpfull by saving gas if a hho generator is installed. If you have o2 sensors in the exhaust pipe, you need a EFIE first!!! more questions, no problem, [email protected], greetings, ****

MAF Enhancer

as in any electronic circuit there has to be a path to and from a componant. the ecm sends a signal along the red wire it will have a certain voltage parameter. the ecm is expecting a return signal of the same voltage if it doesn't get it it will either throw a code if there is no return voltage value or if there is but it is outside the parameters then it will adjust to compensate. there is no need for such an extender ring. the resister should be on the red(imput signal). please rate the solution.. thanks

Hho generator

dont waste you time try to get your money back . ive worked with many of these and not a single one has made any difference. the volume of hydrogen that the generator produces isnt enough to help in fuel millage the alternator on your car cant put out the amperage required to make the quanty needed. alot of scams going on on this stuff right now. just watch your dollar. but since you have it you might as well try it and find out for yourself. i ssen them in the pcv line T in. and ive also see them just tapped into the air cleaner just above the throttle body. good luck and let me know if it works any better for you...

2002 ford mustang gt map sensor enhancer connection? (for HHO)

MAP enhancers usually wont do the trick for long - the computer will learn the adjustment to the MAF and overide within a day or so usually less than a few minutes.

The computer is best altered using an EFIE to adjust the O2 sensor(s), usually adding between .2 and .3 volts to the O2 sensor signals does the trick - each combo of the HHO and car is slightly different - you have to play with it to find your best setting. You only need to alter the signal on the O2 sensors ahead of the cats as they are the ones the computer uses to adjust the fuel.
