  Q: How do you test and replace the IAT sensor on Acura Integra?

  A: With the ignition switch ON, disconnect the electrical connector from the Intake Manifold Temperature Sensor located on the intake manifold. Using an ohmmeter, measure the resistance between the two terminals of the Intake Manifold Temperature Sensor while the engine is cool. Reconnect the electrical connector, start the engine, and warm it up to normal operating temperature. Disconnect the connector again and check the resistance, comparing your measurements to the resistance chart. With the ignition key ON and the engine not running, check the supply voltage at the electrical connector (red/yellow wire) to the sensor, which should be approximately 5.0 volts; if not, trace the red/yellow wire back to the PCM to check for breaks or poor connections. If the wiring is intact and the test results are incorrect, replace the Intake Manifold Temperature Sensor. If the sensor is functioning properly but issues persist, have the vehicle checked at a dealer service department or qualified repair shop, as the PCM may be malfunctioning. To replace the sensor, unplug the electrical connector, remove the screws retaining the sensor to the intake manifold, and take out the Intake Manifold Temperature Sensor, then install the new sensor by reversing the removal steps.
