Dtc P0106 Manifold Absolute Pressure (Map) Sensor Rationality - Daewoo CIELO EURO III Manual

5. This step checks if the reason for no MAP change
was due to a faulty sensor or vacuum source to the
sensor.
6. The MAP sensor vacuum source should be thor-
oughly checked for restrictions. A drill bit can be
used to clean out any casting flash that may exist in
the vacuum port.
7. The MAP sensor vacuum source should be thor-
oughly checked for restrictions. A drill bit can be

DTC P0106 Manifold Absolute Pressure (MAP) Sensor Rationality

Step
Perform an On-Board Diagnostic (EOBD) System
Check.
1
Is the system check complete?
1. Install a scan tool.
2. Turn the ignition switch ON with the engine not
running.
2
3. Compare the Barometric Pressure (BARO)
reading with a known good vehicle.
Is the BARO reading normal for your altitude?
Start the engine while watching the Manifold
Absolute Pressure (MAP) sensor value.
3
Does the MAP sensor value change while starting
the engine?
With the engine still running, snap the throttle while
watching the MAP sensor display on the scan tool.
4
Does the MAP sensor value change rapidly with the
throttle position changes?
1. Turn the ignition switch OFF.
2. Disconnect the MAP sensor vacuum hose and
install a vacuum gauge to the MAP sensor.
5 3. Turn the ignition switch ON, with the engine OFF.
4. Apply 51 kPa (15 in.Hg) to the MAP sensor.
Does the MAP sensor value on the scan tool
change?
1. Turn the ignition switch OFF.
2. Remove the MAP sensor vacuum hose from the
manifold port.
6
3. Inspect the port and the hose for restrictions and
repair as necessary.
Is the action complete?
Repair the restriction in the MAP sensor vacuum
port or hose.
7
Is the action complete?
Replace the MAP sensor.
8
Is the action complete?

9. The MAP Sensor System Performance diagnostic
may have to complete several tests before deter-
mining if the diagnostic has passed or failed the last
test. Operate the vehicle in the Conditions for Set-
ting the DTC several times to ensure that the diag-
nostic runs enough tests to pass or fail.
10. If no faults have been found at this point and no
additional DTCs were set, refer to "Diagnostic Aids"
in this section for additional checks and information.
