That makes a big difference.
Okay, if you have less than 50,000 on your car, this is all warranty. You have a 5 year 50,000 warranty on check engine lights.
The mass air flow sensor has a fault. I posted a flow chart, picture and the part for you to view.

Possible failures are
P0106
Descriptor
Probable Causes
Manifold Absolute Pressure (MAP) Sensor Malfunction
Manifold Absolute Pressure (MAP) Sensor Responding Slowly
Mass Air Flow (MAF) Sensor Malfunction
Flow chart for the failure.
DM: Manifold Pressure Sensors
DM: Introduction See: Computers and Control Systems > Diagnostic Trouble Code Tests and Associated Procedures > DM: Manifold Pressure Sensors - Introduction
DM1 CHECK FOR DTCS
Note:This pinpoint test is designed to diagnose multiple components in the same test steps, only measure the circuits that apply to the vehicle and the component being diagnosed.
Note:Diagnose circuit concerns before range or performance concerns.
Are DTCs P0106, P0107, P0108, P0109, P012B, P012C, P012D, P012E, P0236, P0237, P0238, or P025E present?
Yes
- GO to DM2
.
No
- For symptoms without DTCs, GO to DM2
.
- For all others, RETURN to Section 3 See: Computers and Control Systems > Diagnostic Trouble Code Tests and Associated Procedures > SECTION 3: Symptom Charts
, Symptom Charts for further direction.
DM2 MONITOR THE MAP PID
- Ignition ON, engine OFF.
- For the TCIPT sensor.
- Access the PCM and monitor the TURBO_INLET_V (VOLT) PID.
- For the TCBP or TCBP/CACT sensor,
- Access the PCM and monitor the TCBP_V (VOLT) PID.
- For all others,
- Access the PCM and monitor the MAP_V (VOLT) PID.
Is the voltage between 0.05 - 4.95 V?
Yes
- For DTCs P0106, P012B or P0236, GO to DM9
.
- For all others, GO to DM8
.
No
- GO to DM3
.
DM3 CHECK THE VOLTAGE BETWEEN THE VREF AND SIGRTN CIRCUITS
- Ignition OFF.
- For the MAP sensor,
- MAP Sensor connector disconnected.
- Measure the voltage between:

- For the MAP/CACT sensor,
- MAP/CACT Sensor connector disconnected.
- Measure the voltage between:

- For the MAP/IAT2 sensor,
- MAP/IAT2 Sensor connector disconnected.
- Measure the voltage between:

- For the MAPT sensor,
- MAPT Sensor connector disconnected.
