  Q: How to test and replace the Intake Manifold Temperature Sensor on an Acura Integra?

  A:

  When the ignition is on, unplug the Intake Manifold Temperature Sensor connected to the intake manifold. Place the sensor's terminals at the opposite ends of the ohmmeter probe and check resistance with the engine cold. Attach the power cable back to the sensor, crank your engine, and run it at typical working temperature. When you turn your ignition key to the ON position but don't start the engine, check the sensor's electrical connector (red/yellow wire). Its supply voltage should be around 5.0 volts. If you find no power coming from the red/yellow wire at the PCM, go back along the wire to see if there's a damaged section or loose connection. If everything electrical checks out, install another IAT sensor to resolve the test problem. If your IAT sensor tests properly but the problem continues, take your car to a certified repair shop or dealer service center to check the computer. You'll need to do three basic steps to change the sensor: disconnect the cable connected to the IAT sensor, unscrew the component that holds it to the intake, and pull out the IAT sensor. Installation is the reverse of removal.
