Circuit/System Testing: P0106

  1. Ignition OFF, disconnect the MAP sensor from the vacuum source, leave connected to engine harness.
  2. Connect a J 23738-A  to the MAP sensor.
  3. Turn ON the ignition, with the engine OFF.
  4. Observe the MAP sensor pressure with the scan tool.
  5. Apply vacuum with the J 23738-A  to the MAP sensor in 1 inch Hg increments until 15 inches Hg is reached. Each 1 inch Hg should decrease MAP sensor pressure by 3-4 kPa. Monitor the MAP sensor pressure to see if the decrease in pressure is consistent.
    • If decrease in pressure is not consistent, then test for intermittent and poor connections at the MAP sensor. If connections test OK, replace the MAP sensor.
  6. Apply vacuum with the J 23738-A  until 20 inches Hg is reached. Observe the MAP sensor pressure for less than 34 kPa.
  7. If more than 34 kPa, test for an intermittent and for a poor connection at the MAP sensor. If connections test OK, replace the MAP sensor.
