DIAGNOSTIC PROCEDURE - P0106-MAP SENSOR PERFORMANCE

Test Action
1
NOTE: If a MAP high or low DTC set along with P0106, diagnose the High or Low DTC first before continuing.
Ignition on, engine not running.With the DRBIII®, read DTCs and record related Freeze Frame data.Is the Good Trip Counter displayed and equal to zero?
  1. No --> Refer to the INTERMITTENT CONDITION symptom in the Driveability category.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .

  2. Yes --> Go To 2
2 Ignition on, engine not running.
With the DRBIII®, read the MAP sensor voltage.
Is the voltage below 3.19 volts?
  1. Yes --> Go To 3
  2. No --> Go to 11
3 Turn the ignition off.
Disconnect the MAP sensor harness connector
Ignition on, engine not running.
Measure the voltage of the (K6) Volt Supply circuit in the MAP sensor harness connector.
Is the voltage between 4.5 and 5.2 volts?
  1. Yes --> Go To 4
  2. No --> Go to 8
4 Turn the ignition off.
Disconnect the MAP sensor harness connector
With the DRBIII®, monitor the MAP sensor voltage
Ignition on, engine not running.
Is the voltage between 4.75 and 5.2 volts?
  1. Yes --> Inspect the MAP sensor and the intake for any restrictions, repair as necessary. If okay, replace the MAP sensor.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .

  2. No --> Go to 5
5 Turn the ignition off.
Disconnect the MAP sensor harness connector
Disconnect the PCM harness connector.
Measure the resistance between ground and the (K1) MAP Signal circuit at the MAP sensor harness connector.
Is the resistance below 100 ohms?
  1. Yes --> Repair the short to ground in the (K1) MAP Signal circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .

  2. No --> Go to 6
6 Turn the ignition off.
Disconnect the MAP sensor harness connector
Disconnect the PCM harness connector.
Measure the resistance between ground and the (K1) MAP Signal circuit and the (K4) sensor ground circuit in the MAP sensor harness connector.
Is the resistance below 100 ohms?
  1. Yes --> Repair the (K4) sensor ground shorted to the (K1) MAP Signal circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .

  2. No --> Go to 7
7
NOTE: Before continuing, check the PCM harness connector terminals for corrosion, damage or terminal push out. Repair as necessary.
If there are no possible causes remaining, view repairRepair:Replace and program the Powertrain Control Module in accordance with the service information.

Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .
8 Turn the ignition off.
Disconnect the MAP sensor harness connector
Disconnect the PCM harness connector.
Measure the resistance between ground and the (K6) 5 volt supply circuit in the MAP sensor harness connector.
Is the resistance below 100 ohms?
  1. Yes --> Repair the short to ground in the (K6) 5 volt supply circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .

  2. No --> Go to 9
9 Turn the ignition off.
Disconnect the MAP sensor harness connector
Disconnect the PCM harness connector.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMINALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.

Measure the resistance of the (K6) 5 Volt Supply circuit from the MAP Sensor harness connector to the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
  1. Yes --> Go To 10
  2. No --> Repair the open in the (K6) 5 Volt Supply circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .
10
NOTE: Before continuing, check the PCM harness connector terminals for corrosion, damage or terminal push out. Repair as necessary.
Replace and program the Powertrain Control Module in accordance with the service information.

Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .
11 Turn the ignition off.
Disconnect the MAP sensor harness connector
Disconnect the PCM harness connector.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMINALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.

Measure the resistance of the (K6) 5 Volt Supply circuit from the MAP Sensor harness connector to the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
  1. Yes --> Go To 12
  2. No --> Repair the open in the (K6) 5 Volt Supply circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .
12 Turn the ignition off.
Remove the MAP sensor.
Inspect the vacuum port, check for restrictions or any foreign materials.
Were any restrictions found?
  1. No --> Go To 13
  2. Yes --> Repair as necessary.

    Perform POWERTRAIN VERIFICATION TEST VER - 5 - NGC .
13 If there are no possible causes remaining, view repair
Repair:
Replace the MAP Sensor.
