MASS AIR FLOW SENSOR HOW TO BYPASS
can anyone tell me how to bypass a 96 mx3 dohc 1.6L mass air flow sensor?

Re: MASS AIR FLOW SENSOR HOW TO BYPASS
lol, what are you going to use instead?
you can't run with out one unless you have electronics in place to simulate the 0-5V signal to the ecu (based on load and rpm). OR have a stand alone ems.

OP, do you mean you are wanting to bypass your MAF altogether? or are you talking about taking it off to use throttle body cleaner?
also, what's so wrong w/ your MAF anyway?

Re: MASS AIR FLOW SENSOR HOW TO BYPASS
The easiest way to remove the MAF altogether is with MAP ECU II.
MAP stands for Mean Absolute Pressure. MAP ECU is a device which piggybacks on your ECU and uses a pressure sensor in your intake manifold to determine the mass of air entering the system and communicates that to the ECU. IT can also be used as a stand alone ECU.
I'm also guessing that this is not exactly what you mean. But if you want to run without a MAF that's what you need.

Re: MASS AIR FLOW SENSOR HOW TO BYPASS
Indeed. It needs that MAF to measure how much air is going into the engine, and if it can't do that, than it doesn't know how much fuel to add. This isn't a coolant sensor or even a knock sensor, this MAP sensor is REQUIRED to have the car to run. Try running without one and you'll see it doesn't even want to start, sometimes it will, but just wants to stall. I'm guilty of forgetting to replug the VAF.wytbishop wrote:But if you want to run without a MAF that's what you need.

Re: MASS AIR FLOW SENSOR HOW TO BYPASS
Not exactly. In some cases, like when you're using a very aggressive camshaft, your MAF can give you a false reading. In those cases you need to get rid of it, and use the TPS and MAP for the ECU to calculate the air intake volume. It happens only in extreme cases, but it does happen.

Re: MASS AIR FLOW SENSOR HOW TO BYPASS
Indeed, but you still need an alternative solution, like a MAP. You can't have just nothing.Inodoro Pereyra wrote:Not exactly.

Re: MASS AIR FLOW SENSOR HOW TO BYPASS
Of course. But the op never said he was gonna use nothing. Maybe he already knows how to do the rest.Nd4SpdSe wrote:Indeed, but you still need an alternative solution, like a MAP.

Re: MASS AIR FLOW SENSOR HOW TO BYPASS
Well whats wrong with it is the MAF sensor is not working right my car doesn't want to idle. For me to by a new one it would cost me 1500.00 can't get it at any parts stores, i just wanted to know if you could wire it different or if some one could give me a list of cars that would have the same one it is a 96 mx3 DOHC 1.6l if anyone could help me would be great thanks

Re: MASS AIR FLOW SENSOR HOW TO BYPASS
Look at the sticker on it. I believe it has a big S on it. go to a upull yard, and get any other one with a S on it for $20.

Go to Advance Auto Parts. We have it (remanufactured) for $218.99 + tax, and it comes with a 1 year warranty. The part number is 74-10037.
One other thing: get the old one with you, or else you'll have to pay a $25 core charge.
