2005 Nissan Altima 2.5 showing code PO 0113. Where is the location of IAT sensor and would it be possible for me to check it myself? I trusted someone to do repair on my car and now it won't start at all. Replaced cam/crank sensors, mass air sensor, battery, fuel pump

P0113 ? intake air temperature (IAT) sensor high output

possible cause: bad IAT sensor, wiring, bad ground wire, ECM bad

this car a 2005 altima does not use a iat( intake air temp sensor).what is wrong with the car?

po335 and 725 bad crank sensor and this is also reason for stalling.po 420 catalyst has lost efficiency....needs new catalytic converter ...covered under 8year 80000 mile emmisions warranty.

you need to hook up a scan tool to see what fault is causing check engine light.i would be willing to bet you will get a po335 crank sensor or po 340 cam sensor.high failure rate on these vehicles.

Hi got a Nissan almera 2002 1.5 it won't start it try's to but cuts off it brings code air mass flow I have changed that but still wnt start

0113 Intake Air Temperature Circuit High Input The IAT has told the computer the air temperature is -40 degrees. It can be a faulty IAT sensor, a faulty computer (PCM), or the wiring in between. Until the reading is accurate the computer will use a default value of 140 degrees. The sensor is in the air duct just past the air filter box. Check for a disconnected wire or poor connection at the sensor. With a scan tool, tests can be conducted to determine the faulty component. Here's what you can do without a scan tool. The IAT is a variable resistor, cold makes it gain resistance. You may check the IAT with an ohmmeter, it should not show 100,700 ohms (unless it's -40 degrees outside). If it shows 100,700 ohms, replace the sensor. 23 degrees is 12,300 ohms. 50 degrees is 5,670 ohms. 86 degrees is 2,238 ohms, 212 degrees is 177 ohms. The code is indicating a very high resistance in the sensor, or an open circuit (broken/disconnected wire), or hopefully not the computer. If the sensor's conductivity does not match the air temperature (it will have some resistance unless it is 262 degrees), check the wires. (Make sure key is turned off at least 10 seconds and remains off before disconnecting/connecting PCM connectors.) The two wires both go into Connector 2 (Black) on the PCM (on the right fender). The signal wire (tan) is pin 20. The ground wire (gray) is pin 28. Use an ohmmeter to check the continuity of each wire. Probe from the tan wire at sensor connector (A) to pin 20 of connector 2. It should have no resistance. Likewise, probe from gray wire at sensor connector (B) to pin 28 of Connector 2. It should have no resistance. If the wires check out, wait a couple of days and see if the light goes out. If not, you can go buy a new IAT sensor (even if it did not have infinite resistance) since the only other option is the big bucks PCM. Or you may take it to the dealer and have them diagnose it. But failing all else I would try as a 2nd to last resort replacing the IAT sensor. Check the connector at the sensor carefully for a bent or backed out pin, corrosion. It most likely is a bad sensor, or a bad connection.

Trouble Code: P0113 (4.0L L6 VIN S Auto)
IAT Sensor Circuit High Input Print this code data Number of Trips to Set Code: 1
OBD II Monitor Type: CCM Details
Indicators: MIL Details

• CCM Details

Trouble Code Conditions:
Check with ignition on or engine running; battery voltage more than 10v; The PCM detected the IAT Sensor input was over 4.90v (exc. Dakota, Durango, Ram) or 4.98v (Dakota, Durango, Ram) for 3 seconds.

Possible Causes:

• IAT Sensor signal circuit shorted to VREF (5v)
  
• IAT Sensor signal circuit is open, or the ground circuit is open
  
• IAT Sensor is damaged or it has failed (an internal open circuit)
  
• PCM has failed
  

It could be any of the following
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)

It is small and round (2 wire connector) and located either in the flexiable air intake hose to the engine or in the engine air filter housing.
