Test NTC-6A - Checking Map Sensor Calibration

  1. Turn engine off. Install vacuum "T" in MAP sensor vacuum hose. Install vacuum gauge. Start engine, and let it idle. If engine will not idle, maintain a constant RPM above idle. Using scan tool, read MAP value. If reading is within one in. Hg of vacuum gauge reading, MAP sensor is functioning properly. Test is complete. If reading is not within one in. Hg of vacuum gauge reading, turn engine off.
  2. Disconnect MAP sensor connector. Turn ignition on. Using scan tool in voltmeter mode, check voltage on MAP sensor connector, 5-volt supply circuit (Violet/White wire). If voltage is more than 5 volts, replace MAP sensor. Perform TEST VER-2. If voltage is less than 5 volts, repair open in Violet/White wire. Perform TEST VER-2.
