Great Vid!!! What made you decide to consult the manual to find signal and ground on the Escape? DIYers dont usually have manuals so I was wondering if probing multy wired sensors with a volt meter is still ok in tnis situation?

I was an automotive instructor for 31 years and combined 40 years as a mechanic. I am lucky enough to have access to a good manual resource, so it definitely helps. :). Thank you for your kind comments. Best of wishes. Enjoy your DIY work.

What if you didn't get a reading on The Hertz is the mass flow sensor bad does anybody know thanks

What if you didn't get a reading on the hurts does that mean the mass flow sensor is bad does anybody know thanks for your help

Hi, I am in the process of repairing the mass air flow sensor connector wiring. As a result of the mice messing around, I cut the wires off the connector side, leaving approximately two inches for each wire attached to the connector. I thought each wire was a different color, but I was surprised to find two wires of the same color. I drive a 2006 Infiniti M35 with a maf sensor that has 5 wires in this order from left to right: red, black/white, white, yellow/green, black/white, so I connected the 3 different colored wires and was left confused about the two Of the same color. I tried connecting this to this and vice versa and I did not feel any difference. I also tested them with a multimeter and they both gave the same measurement. So if you have any idea or suggestion that can help, I would be appreciative. thank you

It is very possible that the 2 black white wires are both ground wires that down the line connect to the same place. If this is the case, it wouldn't make a difference on connection. If you can search for and locate a wiring diagram, you can verify this assumption.

Just one note. Disconnect your connector momentarily, key off and measure the resistance between the two black and white wires with an ohm meter. If they are down near 0 to .3 ohms, that is a good condition that they are common to each other.

Good morning Sir..A problem with my Honda jazz car 2005..Module ,Resistor and 2 oxygens sensors replaced..Still problem of heater.Can you help me..Thanks...Merci

It is difficult to do an online diagnosis without assessing the car directly and performing various tests such as fuel pressure, exhaust restriction, compression assessment, ignition, etc, but if you indicate what is going on and what codes you may have, I may be able to suggest an approximate direction.

Mine reads 0.34-0.44 at idle warmed up lol. I think its bad, already tried cleaning it.

I thought the power will be 5 volt. Why not as most sensor are Again how can I know if is digital or analogue before testing Moshitoa south Africa

Thank you! That is a great question. Many vehicles will have a 5 volt return signal voltage when the sensor is unplugged. Once plugged in, however, this will change and vary depending on engine load due to the varied resistance going through the sensor. Some vehicles, however, will use a hz signal on the return wire, and although you can read a voltage on that wire, it won't be very responsive to engine load changes, so the HZ selection must be used on a multimeter to pick it up. The 12 volts that you may be referring to is the actual power feed in the sensor. There may be vehicles out there, though, with up to 12-volt signal return since there are so many different manufacturers, in the world. I am just not presently aware of one at this point. :)
