How do you fix P0100 error code

Hi,here's a link to your P0100 code,it will tell you all about it, P0100 OBD II Trouble Code

A code P0100 may mean that one or more of the following has happened: The MAF (mass air flow sensor) may be disconnected, or a wiring connection may be bad The MAF sensor may be faulty

p0100 is the mass airflow sensor. You might can clean it with carb cleaner first, if still don't work then replace the sensor.

A code P0100 may mean that one or more of the following has happened:
The MAF may be disconnected, or a wiring connection may be bad. The MAF sensor may be faulty
Possible Solutions: Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires. Unplug and reconnect the MAF wiring harness Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information) Replace the MAF sensor.

Error Code: P0130
Fault:
Oxygen Sensor (O2S) 1, Bank 1 - Circuit Malfunction
Possible Cause:
Malfunction Indicator Lamp (MIL) Triggered on first occurrence.
-Wiring harness.
-Oxygen sensor (O2S).
-Engine control module (ECM).

Error Code: P0505
Fault:
Idle Speed Control (ISC) System - Malfunction
Possible Cause:
-Wiring harness.
-Idle speed control (ISC) actuator/Idle air control valve (IAC) valve.
-Throttle motor.
-Throttle valve tight/sticking.
-Engine control module (ECM).

Error Code: P0100
Fault Location:
-Mass Air Flow (MAF) Sensor/Volume Air Flow (VAF) Sensor - Circuit --Malfunction
Possible Cause:
-Wiring harness.
-Mass air flow (MAF) sensor.
-Volume air flow (VAF) sensor.
-Engine control module (ECM).

Error Code: P1491
Fault:
Exhaust Gas Recirculation (EGR) Valve Insufficient Lift
Possible Cause:
-Wiring harness.
-EGR Valve.
-ECM

Error Code:P1607
Fault:
-Engine Control Module (ECM)/Powertrain Control Module (PCM)

Error Code: P0966
Location:
-Pressure Control (PC) Solenoid B - Circuit Low
Possible Cause:
-Wiring short to earth.
-Pressure control (PC) solenoid.
-Engine control module (ECM)/Powertrain control module -(PCM)/Transmission control module (TCM) .

Trouble Code: P1000

OBD II Monitor Testing Not Complete
Possible Causes:


Battery keep alive power (KAPWR) was removed to the PCM One or more OBD II Monitors did not complete during an official OBD II Drive Cycle PCM Reset step was performed with an OBD II Scan Tool

looks like EGR valve is getting block with all the carbon.
take it for a run on motor/high way. high speed in low gear to clear the valves

Hi, you have provided trouble codes p0100 AND p1605.

Trouble Code: P0100


Mass Airflow Sensor Circuit Malfunction
Possible Causes:



Air Intake leaks located after the MAF sensor assembly MAF sensor signal circuit is open, shorted to ground or power MAF sensor has failed PCM has failed

Trouble Code: P1605

A/T Diagnosis Communication Line Malfunction

Possible Causes:


TCM communication line circuit is open or shorted to ground TCM communication line circuit shorted to VREF or power (B+) TCM or PCM has failed TSB 01-004 (01/01) contains information related to this code
For the P0100, check the connector on top of the MAF sesnor for looseness or corrosion. Connector is on top in piocture below.

P0100 OBD-II Trouble Code

Technical Description

Mass Air Flow (MAF) Circuit Malfunction

Basically this means that there's a problem with the Mass Air Flow (MAF) sensor or circuit.

You will likely not notice any serious driving problems, but there may be symptoms like a general decrease in power or sluggishness.
Causes

A code P0100 may mean one or more of the following:

* The MAF may be disconnected, or a wiring connection may be bad.
* The MAF sensor may be faulty.

Possible Solutions

Use an OBD II Reader (or go tou your local parts store and they will for free) and reset the code and see if it comes back.
Then start with the cheapest, easiest repair procedures:

* Check the Mass Air Flow Sensor wiring/harness is connected properly and that there are no broken / frayed wires.
* Unplug and reconnect the MAF wiring harness a few times to clear the contacts.
* Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information).
* Replace the MAF sensor.

P0100 is "massair flow sensor circuit malfunction" and P0116 is "coolant temp. sensor circuit range/performance problem. Acceleration/starting issues? Replace both if the answer is yes. Great cars. The last one I drove was up armored.
