Intake Air Temperature Sensor: Testing and Inspection
Fig 59 Intake Manifold Air Temperature Sensor - Typical
Sensor Resistance Chart (OHMS)
To perform a complete test of the intake manifold air temperature sensor and its circuitry, refer to Powertrain Management/Computers and
Controls/Testing and Inspection/Diagnostic Charts. To test the sensor only, refer to the following;
1. Disconnect the wire harness connector from the intake manifold air temperature sensor (Fig. 59).
2. Test the resistance of the sensor with an input impedance (digital) volt-ohmmeter.
-
The resistance (as measured across the sensor terminals) should be as shown in the Sensor Resistance Chart.
-
Replace the sensor if it is not within the range of resistance specified in the chart.
3. Test the resistance of the wire harness.
-
Do this between the PCM wire harness connector A-15 and the sensor connector terminal.
-
Also check between PCM connector A-4 to the sensor connector terminal.
-
Repair the wire harness as necessary if the resistance is greater than 1 ohm.
