How does the IAT work on a Nissan?
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 Nissan check engine light code.
How to diagnose p0113 Nissan intake air temperature sensor high?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. How much do you know about cars? The cost of diagnosing the P0113 NISSAN code is 1.0 hour of labor.
Where is the intake air temperature sensor located?
– An excessively high voltage from the sensor is sent to ECM. The Intake Air Temperature (IAT) sensor is built into mass air flow sensor or in some vehicles mounted to the air filter duct housing.
What should the IAT reading be on a Honda p0113?
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.

How does the intake air temperature sensor work?
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.
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.
What should the IAT reading on the harness be?
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.
Where is the IAT sensor on an air conditioner?
The IAT sensor is usually located in the air intake boot, but it may also be located in the air cleaner housing or intake manifold. Step 2: Disconnect the negative battery cable.
Can a bad IAT sensor cause fuel economy problems?
The IAT sensor then varies its internal resistance according to air temperature and sends a return signal back to the PCM. The PCM then uses this formation to determine fuel injector control and other outputs. A bad IAT sensor can cause all kinds of drivability problems including a rough idle, surging, stalling, and poor fuel economy.
Where can I find the OBD code for a Nissan?
1. The list of automotive Makes at the right edge of the screen. The currently selected ODB-ii codes is for the Nissan makes. 2. Look up the other OBD II Trouble Codes, please use the search box.
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.
