Not sure what your asking but if you want the wiring diagrams they are copy protected. You can get them at mitchell1diy online. The site does not allow me to copy them over to you.

Disconnect the sensor, use a volt meter (avil from radio shack for less than $6.00) and carefully probe the connector wires with the volt meter set to 200 DC volt scale, with the ignition key turned to run, u will find one wire with about 5.0 volts, that is the reference voltage generated by the computer, that is the hot wire as you call it.

    this is the information, the reference voltage wire is the only wire that has voltage in, the other is signal out and the voltage varies with air flow, very easy to id with a DC voltmeter, this device u are installing is a gimmick, they do not work and may cause engine ping and damage the pistons.

Where is the map sensor located on a 2006 mercury montego?


It doesn't have one , has a mass air flow sensor .
Mass Air Flow (MAF) Sensor The MAF sensor uses a hot wire sensing element to measure the amount of air entering the engine. Air passing over the hot wire causes it to cool. This hot wire is maintained at 200°C (392°F) above the ambient temperature as measured by a constant cold wire. If the hot wire electronic sensing element must be replaced, then the entire assembly must be replaced. Replacing only the element may change the air flow calibration.

Mazda 2003 b2300 running lean on bank 1 it started with ramdom misfire, no spark. and i replace coil, plugs and wires. then it came up with the o2 sensor and replaced one 02 sensor by firewall


Hello! Lets look at this with cause and effect...One of only a few sensors is the cause of a lean mixture...The lean mixture then causes random misfires which in turn causes the O2 sensor to read to much oxygen in the exhaust...

Two sensors control the fuel/air mixture; The Mass Air Flow (MAF) and the Manifold Absolute Pressure (MAP) sensor...Lets eliminate..You'll need an multimeter (digital is best...$20)...The MAF is bolted to the inlet hose to the throttle body...See drawing below...It is combined with the Intake Air Temperature sensor...Pull the connector...Set meter to read 50K Ohms...Locate the pins where the wire colors Gray and Gray/Red connect...Clip meter leads to these pins on the unit...At 77 degrees F you should read 36K ohms...with a hot engine 190 degrees F should read 3.5 K ohms...Notice how as temperature rises the resistance drops...If you do not get these readings the MAF with IAT is the problem...Replace it...If it reads as specified here is the next test...Buy a can of electronic contact cleaner (auto parts store) Remove the MAF from the intake hose...Spray into the air passage...Cleaner leaves no residue and dries quickly...Install, plug in connector and test...If fault has cleared stop there and let me know...NOTE: Using an after market air cleaner that is impregnated with oil will ruin the MAF sensor...Send a comment...Guru...Saailer

Spark plug wire diagram for 2005 mazda 6


2.3L 4 cylinder? After removing the plastic engine cover, look at the top of the ignition coil.

changesparkplugs003.jpg
It should be numbered 1 through 4.

This is plug number 1 on the engine:

changesparkplugs004.jpg
Just wire them 1, 2, 3 and 4 to the corresponding numbers on the ignition coil.

Hi i have a 04 reg mazda premacy 2.0 turbo diesel wich does'nt start it is showing 5 fault codes p0110 iat sensor circuit p0180 fuel temp circuit p0216 injection timing control circuit p1189 pump speed...


P0100 OBD-II Trouble Code

Technical Description

Mass Air Flow (MAF) Circuit Malfunction

Basically this means that there's a problem with the Mass Air Flow (MAF) sensor or circuit.

You will likely not notice any serious driving problems, but there may be symptoms like a general decrease in power or sluggishness.
Causes

A code P0100 may mean one or more of the following:

* The MAF may be disconnected, or a wiring connection may be bad.
* The MAF sensor may be faulty.

Possible Solutions

Use an OBD II Reader (or go tou your local parts store and they will for free) and reset the code and see if it comes back.
Then start with the cheapest, easiest repair procedures:

* Check the Mass Air Flow Sensor wiring/harness is connected properly and that there are no broken / frayed wires.
* Unplug and reconnect the MAF wiring harness a few times to clear the contacts.
* Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information).
* Replace the MAF sensor.

I need to clean/replace the mass air inflow sensor. How to?


In your vehicle, the Mass Airflow Sensor is attached to the air filter assembly.

b65641c.jpg

Fig. The exposed -hot wire- of the MAF sensor


The MAF sensor uses a hot wire sensing element to measure the amount of air entering the engine. Air passing over the hot wire causes it to cool. This hot wire is maintained at 200°C (392°F) above the ambient temperature as measured by a constant cold wire. If the hot wire electronic sensing element must be replaced, then the entire assembly must be replaced. Replacing only the element may change the air flow calibration.

The current required to maintain the temperature of the hot wire is proportional to the mass air flow. The MAF sensor then outputs an analog voltage signal to the PCM proportional to the intake air mass. The PCM calculates the required fuel injector pulse width in order to provide the desired air/fuel ratio. This input is also used in determining transmission electronic pressure control (EPC), shift and torque converter clutch scheduling.



Removal & Installation
  1. Before servicing the vehicle, refer to the Precautions section.
  2. Disconnect the battery ground cable.
  3. Disconnect the MAF sensor electrical connector.
  4. Remove the two retaining screws and the MAF sensor.
  5. To install, reverse the removal procedure.
