Circuit/System Testing

  1. Turn ON the ignition, with the engine OFF.
  2. Disconnect the MAP sensor.
  3. Connect a test lamp between the MAP sensor 5-volt reference circuit and a good ground.
  4. Measure for a proper range of 4.8-5.2 volts between the MAP sensor 5-volt reference circuit and a good ground.
    • If the voltage is less than the specified range, then test the circuit for a high resistance or a faulty ECM.
    • If the voltage is more than the specified range, then test the circuit for a short to voltage or a faulty ECM.
  5. With the MAP sensor still disconnected, use the scan tool to observe the MAP Sensor parameter for the proper value of less than 12 kPa.
    • If the MAP Sensor parameter is more than 12 kPa, then test the MAP sensor signal circuit for a short to voltage or a faulty ECM.
  6. Connect a jumper wire between the MAP sensor 5-volt reference circuit and the MAP sensor signal circuit.
  7. Use the scan tool to observe the MAP Sensor parameter for the proper value of more than 103 kPa.
    • If the MAP Sensor parameter is less than 103 kPa, then test the MAP sensor signal circuit for a high resistance or a faulty ECM.
  8. Turn OFF the ignition, and all electrical accessories. Allow sufficient time for the control module to power down before taking a resistance measurement.
  9. Measure for a proper value of less than 5 ohms of resistance between the low reference circuit of the MAP sensor and a good ground.
    • If the resistance is more than 5 ohms, then test the circuit for a high resistance or a faulty ECM.
  10. If the MAP sensor circuits test normal, then replace the MAP sensor.
