'97 Rover 4.0 MAF Sensor wiring

[vjm530]

Hi,

New to the neighborhood and look forward to sharing LR RR info.

I need your help on a question. I have a '97 Rover 4.0 and I'm trying to find out which of the 3 wires on my MAF Sensor supplies the voltage to the sensor. I need this info so I can tap into this line to install a Sensor Enhanser. From the schematic I have it looks like the Red/Blue wire #3 is ground but I don't know the color of #1 - ignition or #2 - voltage (which is the one I need) from the schematic.

Any help would be sooooo grateful. Thanks.

dont ever touch the lines on the maf sensor, fuck up the resistance and it will cause all sorts of issue with fueling and may even cause it to stall and not start again. any sensor enhancer is just a crock of shit. Dont fuck with a sensor or else get some really costly repair bills.

Your foul mouth response is very ignorant at best and definitely unsolicited. Before making such an irresponsible statement I suggest you research your opinion before posting. MAF Sensor Enhansor's are a necessary requirement with the installation of HHO systems that are being installed in million's of 'American' cars to help with better fuel economy and the rising gas prices. This device does not harm anything and is totally controllable. Maybe you should keep your crude comments 'down under'.

Awhile this may not be the same sensor, the connector pinouts may be similar. Do you know how to use a voltmeter?

Thanks for your 'positive' feedback. Actually, my connector has only 3 pins/wire. Looks like I will need to borrow a meter. I just thought maybe someone on this forum would already know. Thanks again.

One with be ground
One with be 12v and the last will be the varying voltage output from the sensor.

Thanks Adam for your help. Yes, I know from my schematic what wire connects to where. My problem is the schematic gives the '#' of the pin but not the 'color'. My wires are red w/black, blue (thin) and orange (maybe brown). I need to know which color is #2 which is the voltage lead that I will splice into.

#1 - output from sensor
#2 - 12v
#3 - ground

If you pull the plug off the MAF you should be able to match up the pin with the correct color wire.

If not you could always use a needle probe from a voltomoter. (or how ever you spell it)

What is this "enhancer" you speak of?

Post details, i am quite sceptical.

Also, once you instal it tell us how much better your truck works.....

The enhancer is a fixed resistor or (adjustable 1kiloohm linear taper potientometer) that fools the ECU into thinking you are driving in very cold weather, adding max fuel into your air/fuel mix.

A good kit has the proper connectors / the bad kit just ships you the resistor and you have to figure out where to solder it in.

There are better ways to do this but it's there.

I have a dual Enhanser (2 pots w/switches) setup that allows you to switch between Town & Hwy driving. You dial up more gas or hho and then leave it and very easy to install. 3 wires. 1 goes to ground and the other 2 between the voltage going to the MAF. The controls are mounted somewhere near you and then the wiring goes to the MAF under the hood.

Speaking of . . . does anyone know of an accessible access to the engine from the drivers seat through the firewall? I can't find any opening that I can pass a 3/8" line from the drivers seat to the MAF sensor which is on the drivers side about 2-3' in front of the driver. Any help would be grateful as I have pulled the panel under the steering wheel to see if there is any existing routing to pass the line through but nothing I can see. Thanks.
