calculated airflow that is derived from the system of models for more than 2 s.

Action Taken When the DTC Sets

DTC P0106 is a Type B DTC.

Conditions for Clearing the MIL/DTC

DTC P0106 is a Type B DTC.

Diagnostic Aids

* A wide open throttle (WOT) acceleration from a stop should cause the MAP sensor parameter on the scan tool to increase rapidly to near the

BARO parameter at the time of the 1-2 shift.

* The BARO that is used by the ECM to calculate the air flow models is initially based on the MAP sensor at ignition ON. When the engine is

running, the ECM will continually update the BARO value near WOT using the MAP sensor and a calculation. A skewed MAP sensor will

cause the BARO value to be inaccurate.

Circuit/System Verification

1. Verify that DTC P0641, P0651, or P0697 is not set.

瀚慖f any of the DTCs are set, refer to DTC P0641, P0651, P0697, or P06A3 (LF1) (See: P Code Charts/P0641/ECM).

2. Verify that restrictions do not exist in the exhaust system. Refer to Restricted Exhaust (See: Engine, Cooling and Exhaust/Exhaust

System/Testing and Inspection/Restricted Exhaust).

3. Ignition OFF for 90 s, determine the current vehicle testing altitude.

4. Ignition ON, engine OFF, observe the scan tool BARO parameter. Compare the parameter to the Altitude Versus Barometric Pressure (See:

Powertrain Management/Computers and Control Systems/Specifications/Altitude Versus Barometric Pressure) table. The BARO parameter

should be within the specified range indicated in the table.

5. Use the scan tool and compare the MAP Sensor parameter to a known good vehicle, under various operating conditions. The reading should

be within 5 kPa of the known good vehicle.

6. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the

conditions that you observed from the Freeze Frame/Failure Records data.

Circuit/System Testing

1. Verify the integrity of the entire air induction system by inspecting for the following conditions:
