You don't change parts when you get a code. The codes are a starting point for diagnostic testing.
Codes are the symptoms of a possible problem,such as an out of range or defective sensor. Codes don't mean you change something. It's not that simple or are vehicles designed as such. You always test,then replace. You can't do either, if you don't know the system your working on.
The MAF and IAT Sensors are both in the MAF,one piece in most cases.

What are your issues ? Not likely a MAF gone bad.
Do you have the air filter cover on tight and no duct work leaks or vacuum leaks? That's what's possibly setting the code for the MAF.

I am getting a p190 after installing a maf which indicated code p0113. The p0190 only appeared once the new maf was installed. Thanks


code p 0190 refers to fuel rail pressure(FRP) sensor--circuit malfunction===causes wiring---FRP sensor---ECM
check that you have not dislodged a wire while carrying out the maf repair code p 0113 refers to intake air temperature(IAT) sensor--circuit malfunction===causes wiring open circuit / short to positive ---wiring short to ground ---ground wire defective ---IAT sensor --ECM
the original code had nothing to do with the MAP sensor

2005 ford taurus with a p0113 code saying high circuit


p0113 means you are getting a very high voltage reading from the IAT sensor to the ECU. Usually this is because the IAT has become faulty or bad. Replace and clear codes it should go away.

Where the intake air temp sensor on my 03 ford 250


IAT --provides the sequential fuel injection temperature info

About 18 sensors, solenoids & switches --are used or monitored for shift control strategy


The AIT should be in with the MAF Sensor


Try cleaning it CRC MAF Cleaner --instructions on the can


Why are you asking about OD?

Need the color of the two wires going from the plug to the iat/maf sensor on a 2006 ford taurus


The first and sixth wire are IAT.------

That is grey wire and grey with red wire.-------

The first one is only grey and second one is gery/red wire.

2001 ford taurus 3.0(2) codepo174, changed oxygen sensors and fuel filter code still comes up on memory


This code is usually caused by leaking intake manifold gasket on the front side. With the engine running, spray carb cleaner or ether on the gaskets. If the engine revs at all, you have a leaky gasket. If not, check for other vacuum leaks in anything attached to that side of the manifold. If you have more questions, please let me know.

Diagnostic codes


P0102 OBD-II Trouble Code - Mass Air Flow (MAF) Circuit Low Input

What does that mean?
Basically this means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. A more technical description would be that the MAF circuit had lower than expected voltage (air flow). Other MAF sensor circuit DTC trouble codes are P0100, P0101, P0103, and P0104.

Symptoms
You will likely not notice any serious drivability problems, although there may be symptoms such as a general decrease in power or sluggishness.

Causes
A code P0102 may mean that one or more of the following has happened:
* The MAF may be disconnected, or a wiring connection may be bad
* The MAF may be dirty or otherwise contaminated (Note: if you use a reusable oiled air filter, be careful not to apply too much oil or that can contaminate the MAF).
* The MAF sensor may be faulty
* The vehicle computer may be faulty (very rare)

Possible Solutions
The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:
* Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
* Inspect for any air leaks near the MAF sensor.
* Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor.
* Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
* Replace the MAF sensor.


P0113 - Intake Air Temperature Circuit High Input

What does that mean?
The powertrain control module (PCM) monitors the temperature of the air entering the engine. The PCM supplies a 5 volt reference voltage to the Intake Air Temperature (IAT) sensor. The IAT is a thermistor that varies resistance based on temperature. As the temperature increases, resistance decreases. Low temperature results in a high signal voltage. When the PCM sees a signal voltage higher than 5 volts, it sets this P0113 check engine light code.

Potential Symptoms
There will likely be no symptoms other than illumination of the Malfunction Indicator Lamp (MIL - Check Engine Light / Service Engine Soon).

Causes
A code P0113 may mean that one or more of the following has happened:
* Internally failed IAT sensor
* Faulty connection at IAT sensor
* Open in IAT ground circuit or signal circuit
* Short to voltage in IAT signal circuit or reference circuit
* IAT harness and/or wiring routed too close to high-voltage wiring (e.g. alternator, spark plug cables, etc.)
* Faulty PCM (less likely but not impossible)

Possible Solutions
First, if you have access to a scan tool, is there an IAT reading? If the IAT reading is logical then the problem is likely intermittent. If the reading is less than -30 degrees, unplug the connector. Install a jumper wire between the harness connector signal and ground circuits. The IAT temperature reading on the scan tool should be maxed out at the high end. For example it should be 280 degrees Farenheit or higher. If it is, the wiring is okay, and it may have been the connection. If it isn't install the jumper wire between the IAT signal circuit and the chassis ground. If now the IAT reading on the scan tool is maxed out then check for an open in the IAT ground circuit. If you get no reading at all on the scan tool, it's likely that the sensor signal is open or the 5 volt reference is missing. Check using a DVOM (digital volt ohm meter) for a 5 volt reference. If it's there, then unplug the connector at the PCM and check for continuity on the IAT signal circuit between the PCM connector and the IAT connector.

I really hope help with this (remember rated this).

My 2000 ford focus has codes p0102 and p0113 whats that and what could it be?


P0102 - Mass Air Flow (MAF) Circuit Low Input
The MAF sensor circuit is monitored by the PCM for low air flow (or voltage) input through the comprehensive component monitor (CCM). If during key ON engine running the air flow (or voltage) changes below a minimum calibrated limit, the test fails. MAF sensor disconnected
MAF circuit open to PCM
VPWR open to MAF sensor
PWR GND open to MAF sensor
MAF RTN circuit open to PCM
MAF circuit shorted to GND
Intake air leak (near MAF sensor)
A closed throttle indication [throttle position (TP) sensor system]
Damaged MAF sensor
Damaged PCM
A MAF V PID (MAF PID) reading less than 0.23 volts (Refer to equivalent grams/second chart in GO to Pinpoint Test DC ) in continuous memory or key ON and engine running indicates a hard fault.
P0113 - Intake Air Temperature (IAT) Circuit High Input Indicates the sensor signal is greater than Self-Test maximum. The IAT sensor maximum is 4.6 volts or -50°C (-58°F). Open circuit in harness
Sensor signal short to power
Damaged sensor
Improper harness connection
Damaged PCM
IAT V PID reading greater than 4.6 volts with key ON and engine OFF or during any engine operating mode indicates a hard fault.

2003 ford taurus idle problems had trouble codes


A code P0174 may mean that one or more of the following has happened:
  • The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
  • There could be a vacuum leak downstream of the MAF sensor. and your solutions are.
    • In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner . Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
    • Inspect all vacuum and PCV hoses, replace if necessary
    • Check for a dirty fuel filter and proper fuel pressure

1996 Ford Taurus Chugging MAF


Did you buy a Ford MAF sensor? There are some brands that are not reliable or accurate. Buy a Ford MAF sensor, if your mechanic has decided that the MAF is faulty. You may have a leaking fuel injector, bad coolant temp sensor,bad oxygen sensor,dirty air filter, clogged exhaust system.
