Intake air temp is on the air breather. you can test the resistance with a blow dryer. disconnect it and verify resistance between 2 poles while cold. send hot air with blow dryer in the passage and test again. if it don't change, replace sensor. make sure you clean the passage and the sensor to proceed with test

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.

Gives a error code P0113 and does not start. It cranks but does not start?


you need to replace a sensor
Intake Air Temperature could also mean the Maf needs a clean

error code explained
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

What does code 13 mean for a 2000 mercury cougar


If you mean P0113 then it is an intake air temperature circuit high output. Which means some of the possible problems could be a dirty air filter, defective intake air temp. sensor, defective MAF sensor, or faulty or corroded air intake temp sensor.
Now if it code
P0133 then the cause would be an O2 sensor. Which is bank 1 sensor 1.
In some cases on older vehicles code 13 means there are no problems but that was back in 95 and before.

I have a 2007 Chevy hhr and the codes are p0102 p0113 p0171 and p0300 it won't start when I first turn the key but when I do it the second time it starts up so what could be the problem


p0102 is your Mass Air Flow device.
p0113 is "air intake temperature" sensor voltage too high.
p0171 is "engine running too lean"
p0300 is "random misfire"

You can pretty much ignore your p0113, p0171 may be caused by a bad MAF, and p0300 may be caused by your p0171.

the actual indication for your MAF is that the voltage getting to the computer from the MAF is too low. It could be a bad MAF, or bad wire between the MAF and the computer.

Replaced the MAF. Still have the P0113 code. Car runs fine. Cannot find another intake air temperature sensor anywhere on the vehicle! Where is it?


code p0113 does not refer to a MAF sensor so replacing that was a waste of money=== It refers to intake air temperature (IAT) sensor---circuit malfunction====causes --wiring open circuit/short circuit to positive--wiring short circuit to ground---ground wire defective---IAT sensor---ECM.
Replace the IAT and check the wiring is in good condition and the connectors are clean and tight.

I have 3 codes po431 po103 and po113


P0103 Mass or Volume Air Flow Circuit High Input P0113 Intake Air Temperature Circuit High Input P0431 Warm Up Catalyst Efficiency Below Threshold (Bank 2) A code P0431 may mean that one or more of the following has happened:
  • The catalytic converter is no longer functioning properly
  • An oxygen sensor is not reading (functioning) properly
  • There is an exhaust leak
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 plugmag-glass_10x10.gif cables, etc.)
  • Faulty PCM (less likely but not impossible)
A code P0103 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 sensor may be damaged
  • The vehicle computer may be faulty (very rare)

Hello, I had my car hooked up to a computer today and the codes P102, P0113, and P111 came up. The engine misses when driving down the road, and the car frequently dies when turning corners and idling. ...


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). Possible causes are Open circuit in harness, Sensor signal short to power, Damaged Sensor, Improper harness connection, Damaged PCM

P0102 Mas 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. Possible causes are MAF sensor disconnected, MAF circuit open to PCM, VPWRopen to MAFsensor, PWR GND open to MAF sensor, MAF RTN cirbuit open to PCM, MAF circuit shorted to GND, Intake air leak (near MAF sensor), A closed throttle indication, Damaged MAF sensor, Damaged PCM.

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!

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).

Changed maf sensor because of p0113 code stillhave problem after i changed sensor battery light came on fixed bad belt could belt have caused the pcm to not read the 5v it needed to wor k the iat sensor?


P0113 is air temp circuit high. The maf sensor (mass air flow) sensor just measures the amount of air entering the engine. The iat (intake air temp) sensor is the one that detects the temperature of the air.
Change that sensor, and the code should disappear. It is located in the intake manifold or air plenum.
