Conditions for Running the DTC
* DTCs P0102, P0103, P0107, P0108, P0112, P0113, P0116, P0117, P0118, P0128, P0335, P0336 are not set.
* The engine is running.
* The IAT Sensor parameter is between -7 and +125掳C (+19 and 257掳F).
* The ECT Sensor parameter is between 70-125掳C (158-257掳F).
* This DTC runs continuously when the above conditions are met.
Conditions for Setting the DTC
The engine control module (ECM) detects that the MAP sensor pressure is not within range of the calculated pressure that is derived from the
system of models for more than 0.5 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
Note: Verify that the engine is in good mechanical condition before continuing with this diagnostic.
* A skewed or stuck engine coolant temperature (ECT) or IAT sensor will cause the calculated models to be inaccurate and may cause this
DTC to run when it should not. Refer to Temperature Versus Resistance (See: Powertrain Management/Computers and Control
Systems/Specifications/Temperature Versus Resistance).
* 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 wide open throttle using the MAP sensor and a calculation. A skewed MAP
sensor will cause the BARO value to be inaccurate. Use the scan tool and compare the BARO parameter at ignition ON to the Altitude vs.
Barometric Pressure Table. Refer to Altitude Versus Barometric Pressure (See: Powertrain Management/Computers and Control
Systems/Specifications/Altitude Versus Barometric Pressure).
* A skewed MAP sensor will also cause the first and second intake manifold models to disagree with the actual MAP sensor measurements.
Use the scan tool and compare the MAP Sensor parameter to a known good vehicle, under various operating conditions.
* Inspect for worn piston rings. Refer to Engine Compression Test (See: Engine, Cooling and Exhaust/Engine/Compression Check/Testing
and Inspection).
