Question about 2002 Ford Mustang

Open Question

Ok so my 02 mustang gt was throwing a code forever, witch was P0113, intake air tempature sensore high input. after finding out my intagrated iat sensor was malfunctionaing i replaced it with a external one on my cold air intake. ever since then ive been getting codes P0171 and P0174 both banks system running too lean. i can not get them to go away. ive tried checking the fuel pressure. the fuel filter was changed i cleaned my MAF checked for vaccum leaks didnt find any fuel injectors are working didnt check farther then that. im tired of seeing service engine soon please help.

SOURCE: Code #P0171 & code #P0174

The most common problem on a Ford with these codes is deteriorated PCV hoses. Check the hoses from the PCV valve to the intake manifold. Pay special attention to the rubber elbows. They often crack on the inside curve and the crack is hard to see.

SOURCE: check engine light

this is very common on these. the upper intake seals leak and should be replaced. It is not a noticable vacuum leak and is usually worse when the engine is cold. It is not a very difficult job to do

SOURCE: 1999 F-150, approx 123k miles,

Start with the cheap and easy fix attempt first. Inspect for a disconnected air hose. Next, the Mass Airflow sensor may need cleaning due to an air filter having not been properly seated and allowing debris to get past the filter. Or even the use of a oil ype air filter can cause this. The screen gets the wings of flies or oil caught on it and an uneven flow of air causes the sensor to read things incorrectly. Cleaning can easily be done with a good rinsing of warm water in the kitchen sink then blow dry before reinstall. If it is oily use an electronic cleaner to remove the oil deposits. If the problem codes still return look more closely for a leak at a manifold gasket. If still nothing then on the fuel delivery side of things your fuel pump may be failing.

SOURCE: changed maf sensor because of p0113 code stillhave

The resistance at the MAF sensor should be lower than 16k ohms between the A and F terminal. If it is, then the sensor is ok. Measure voltage at the F terminal (harness) should be 5V. If all is ok it MAY need a pcm, but I would have a professional shop ck it first.

Undefinedas replacement on civic 98 sensor p0113

Possible causes for this code are: - Faulty Intake Air Temperature (IAT) sensor
- Dirty air filter
- Intake Air Temperature (IAT) sensor harness is open or shorted
- Intake Air Temperature (IAT) sensor circuit poor electrical connection. this code sets when: - An excessively high voltage from the sensor is sent to ECM. Usual Possible symptoms - Engine Light ON (or Service Engine Soon Warning Light) P0113 1998 Honda Civic Description The Intake Air Temperature (IAT) sensor is built into mass air flow sensor or in some vehicles mounted to the air filter duct housing. The sensor detects intake air temperature and transmits a signal to the Engine Control Module (ECM).The temperature sensing unit uses a thermistor which is sensitive to the change in temperature. Electrical resistance of the thermistor decreases in response to the temperature rise. The Intake Air Temperature signal is used as an input for various systems in the vehicle.

Tune up code 2196 what is this?

P2195 is 02 sensor stuck lean ( bank 1 sensor 1 )--check for a possible vacuum leak in all vacuum lines.-- if no vacuum or other leaks could be egr valve. p2196 is the same but stuck rich,p0053 is ho2 sensor bank 1 sensor 1 heater resister all codes are related to the o2 sensor, p0113 is intake air tempurature curcuit high input ( IAT ). check wiring or senser replace if need be. if you can not find any leaks and egr system is ok, then its the 02 sensor causeing this.

P0113 code for the intake air temperature sensor

Thank you for the inquiry.
Intake Air Temperature Circuit High Input
P0114 Intake Air Temperature Circuit
P0113 - Intake Air Temperature Circuit High Input

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:
1. 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. 2. If it isn't install the jumper wire between the IAT signal circuit and the chassis ground.
3. 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.

The car has 2 codes first p0113 then p1627

P0113 - Intake Air Temperature Sensor (IAT sensor) Circuit High Input. Possible causes - Dirty air filter
- Intake air temperature (IAT) sensor harness is open/disconnected or shorted
- Intake air temperature (IAT) sensor electrical circuit poor connection
- Faulty intake air temperature sensor. P1627 PCM/ECM A/D Conversion Error

This is a code indicating that the on-board computer could not convert a piece of data it was given by one or more sensors. This one must be taken in and read the freeze frame data to see under what condition it detected an error and tech has to chase this problem. they will want to put a PCM in it and reprogram. no good news for this problem except have the code cleared for now and hope it doesn't come back.

Took my focus 2003 to autozone it is going thru alot of gas and we changed the spark plugs they ran a test and the codes are po113 & po303 i do not know what this means can you help me

P0113 indicates the IAT Intake Temperature Sensor has a problem.
P0303 indicates a misfire on cylinder 3

I believe the IAT is built into the MAF sensor located in the air snorkle and helps regulate the air/fuel mixture. Also concentrate on cylinder 3 looking for problems such as injector, wiring, etc.

Hope this helps!

2001 malibu shifts rough

code p0113 means: IAT sensor high temp

and the solution:
The Intake air temp sensor is located inside the air flow meter and uses yellow and black wire and the black wire. IAT sensor circuit code P0113 indicating excessively high voltage or (Open Circuit) the ECM is either not seeing the correct voltages at terminals 66 and 80 under the dash at the ecm. It could be as simple as a broken wire under the insulation right at the air flow meter, Or a little worse a bad air flow meter. There are cheeper remanufactured Aair flow meters available at Nissan for your car around $150 instead of $400 like they used to be new.
