P1101 MAF out of self test range-is this a simple fix? or a dealer fix?

https://www.yourmechanic.com/article/p1101-obd-ii-trouble-code-mass-airflow-sensor-out-of-self-test-range-by-cheryl-knight

p0102 is MAF mass air flow , circuit low input. Try these to reset code by trying following.
Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires. Inspect for any air leaks near the MAF sensor. Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor. Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information) Replace the MAF sensor.
P0121 Throttle Position Sensor/Switch A Circuit Range/Performance Problem
P0108 EGR Barometric Pressure Sensor Input Signal is out of self test Range. P0300 Random Misfire Detected.

DTC P0121: Throttle Position (TP) Sensor 1 Performance
Circuit/System Description
The engine control module (ECM) uses the following information to calculate an expected airflow rate:
?€¢
The throttle position (TP)

?€¢
The barometric pressure (BARO)

?€¢
The manifold absolute pressure (MAP)

?€¢
The intake air temperature (IAT)

?€¢
The engine RPM

P0121 The predicted air flow and the predicted MAP combined are outside a calibrated range for more than 3 seconds.
Circuit/System Testing

1. Inspect for the following conditions:
?€¢
Vacuum hoses for splits, kinks, and proper connections as shown on Vehicle Emission Control Information label



?€¢
Inspect thoroughly for any type of leak or restriction



?€¢
Air leaks at throttle body mounting area and intake manifold sealing surfaces



?€¢
Throttle body for dirt, debris, and coking--Refer to Throttle Body Cleaning.


2. Allow the engine to reach operating temperature. Observe the MAP Sensor Voltage parameter with a scan tool. Voltage should be more than 0.8 volt and less than 4 volts.
?‡'
If more than 4 volts or less than 0.8 volt, refer to DTC P0106.

3. Idle the engine. Observe the MAP Sensor kPa parameter with a scan tool. Increase the engine speed slowly and then back to idle. The MAP sensor kPa should change smoothly and gradually as engine speed is increased and returned to idle.
?‡'
If the MAP sensor kPa does not change, refer to DTC P0106.

4. Take a snapshot of the engine data list while performing the actions listed below. The mass air flow (MAF) sensor g/s should change smoothly and gradually as the engine speed is increased and is returned to idle.
?€¢
Idle the engine.



?€¢
Increase the engine speed slowly to 3,000 RPM, then back to idle.



?€¢
Exit from the snapshot and review the data.



?€¢
Observe the Mass Air Flow (MAF) Sensor parameter frame by frame with a scan tool. The MAF sensor g/s should change smoothly and gradually as the engine speed is increased and is returned to idle.



?‡'
If the MAF sensor g/s does not change smoothly and gradually as the engine speed is increased and is returned to idle, refer to DTC P0101 or P1101.


5. Inspect the throttle body for the following conditions:

?€¢
Loose or damaged throttle blade

?€¢
Broken throttle shaft

?€¢
Any throttle body damage

?‡'
If any of these conditions exist, replace the throttle body assembly.

p0171 is a lean condition on the oxygen sensor from the side of the engine that is the same side as cylinder 1. The other p1101 is an air flow issue that is most likely a vacuum leak that is causing the 171 error. Check all the vacuum lines on the engine and see if any are loose and also see if there is any damage to the PCV valve from the battery leaking.

P0102 - Mass Air Flow (MAF) Circuit Low Input
The MAF sensor circuit is monitored by the PCM for low air flow (or voltage) input through the comprehensive component monitor (CCM). If during key ON engine running the air flow (or voltage) changes below a minimum calibrated limit, the test fails. MAF sensor disconnected
MAF circuit open to PCM
VPWR open to MAF sensor
PWR GND open to MAF sensor
MAF RTN circuit open to PCM
MAF circuit shorted to GND
Intake air leak (near MAF sensor)
A closed throttle indication [throttle position (TP) sensor system]
Damaged MAF sensor
Damaged PCM
A MAF V PID (MAF PID) reading less than 0.23 volts (Refer to equivalent grams/second chart in GO to Pinpoint Test DC ) in continuous memory or key ON and engine running indicates a hard fault.
P0113 - Intake Air Temperature (IAT) Circuit High Input Indicates the sensor signal is greater than Self-Test maximum. The IAT sensor maximum is 4.6 volts or -50°C (-58°F). Open circuit in harness
Sensor signal short to power
Damaged sensor
Improper harness connection
Damaged PCM
IAT V PID reading greater than 4.6 volts with key ON and engine OFF or during any engine operating mode indicates a hard fault.

The O2 sensor located on the exhaust system must be checked.
Sensor and wiring must be tested using a multimeter.

Same thing for the MAF sensor located on air intake.

There are several things that can cause the flashing light. sometimes a simple fix is the change the RABS, this sensor is on the rear differiential and is not too expensive. Change it. Pull th epositive cables off of your batteries fro 15 minutes. Hook them back up and see what happens.
