JUST THE FACTS StandardBrand com IntermotorImport com Air Charge Manifold Temperature Sensors Chrysler AX49 Air Charge Manifold Temperature Sensor Ford AX25 What does an Air Charge Manifold Temperature Sensor do The Air Charge Manifold Temperature sensor is used by the computer to measure air density for fuel mixture control The computer uses this information to trim the air fuel ratio according to the air density Where are the Air Charge Manifold Temperature Sensors located They are located either in the intake air tubing or intake manifold and may be incorporated into the MAF sensor Will a malfunctioning Air Charge Manifold Temperature Sensor illuminate the check engine light or affect vehicle operation Yes a failing sensor can illuminate the MIL and may cause the engine to run rich or lean as a result of a failed sensor and may idle poorly especially when cold GM TX3 Honda AX39 What are the common causes of failure Typically these sensors fail due to exposure to the under hood heat from engine operation Collecting debris on the sensor element may also cause it to operate improperly How to determine if these sensors are malfunctioning A DTC will be set if an abnormal reading occurs P0112 low input or P0113 for a high input The air charge manifold sensor temperature reading should closely match the engine coolant temperature reading on a scan tool if the engine has not been run for over an hour The sensor circuit can be checked for proper voltage using a voltmeter Nissan What makes Standard and Intermotor Air Charge Manifold Temperature Sensors the best AX50 As basic manufacturers Standard and Intermotor have complete control of the manufacturing process from componentry to finished product Temperature sensor design specifies tight tolerance thermistor response values to assure accuracy of the temperature measurement and proper part operation All Air Charge Manifold Temperature sensors are 100 factory tested to ensure trouble free performance Toyota AX33 ST10235AX FEB14
