Description
OBD-II Trouble Code Description for P0113 Jaguar
Intake Air Temperature Sensor 1 Circuit High
What does this mean?
OBD2 Code P0113 Jaguar definition:
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 Jaguar check engine light code.
Symptoms
Possible sumptoms of OBD code P0113 Jaguar
There will likely be no symptoms other than illumination of the Malfunction Indicator Lamp (MIL – Check Engine Light / Service Engine Soon).
Causes
Possible causes of OBD code P0113 Jaguar
?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.

Note:
1. The list of automotive Makes at the right edge of the screen. The currently selected ODB-ii codes is for the Jaguar makes.
2. Look up the other OBD II Trouble Codes, please use the search box. Enter the 5 character trouble codes in the search box and submit the search.
3. Don’t assume a particular OBD-II code means the same for other auto manufacturers as there are many makes specific codes in use.
4. If your OBD-II trouble codes are for a different car, select that vehicle series before searching for the diagnostic codes because not all OBD2 codes used by one manufacture are used by the other makes.
