Thats alot of codes, and most likely your vehicle has multiple problems. an 04 explorer gets it baromnetric pressure signal via the MASS-AIR sensor near the air cleaner. If there is a problem with that sensor, the intake air, barometric pressure, engine load calculation and main fuel calculations will all be affected or disabled causing the vehicle to run poorly or possibly not at all. Id recommend testing it using fairly advanced equipment and procedures. an OBD2 capable scantool that has datastream and snapshot ability at the very least , coupled with a volumetric efficiency calculator will tell you how well the MAF is doing its job if it is working at all. a labscope or good multimeter can also be used but they are less exact.
Depending on the type of fault and the fuel trim results, the entire problem could be in the Mass Air sensor circuit or its air flow sealing.

The EGR code is a seperate system. worst case if the EGR valve is stuck wide open it could also be a contributing factor to poor idling and MAF sensor codes and r=terrible mileage, however the EGR uses a sensor called Delta Pressure Feedback-EGR. (DPFE for short). This sensor measures the flow of the EGR by checking the differences in 2 different hoses coming off the EGR feed pipe; If either hose has a problem, you get EGR codes, if the valve has a proiblem you get codes, or if the DPFE has a problem, yes, you get codes. the DPFE sensors fail OFTEN! But I would still always verfify function using a scantool with enhanced ford datastream and manual activation ability before recommending a part.

06 f250 5.4 code r107


Do you mean p0107 ? If so that is P0107 Ford - Manifold Absolute Pressure/Barometric Pressure Sensor Low Input

Possible causes
- Faulty Manifold Absolute Pressure sensor
- Manifold Absolute Pressure harness is open or shorted
- Manifold Absolute Pressure sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM) help.jpg What does this mean?
When is the code detected?
The ECM has detected a performance fault with the MAP sensor
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Engine rough idle
- Engine hesitation
P0107 Ford Description
The Manifold Absolute Pressure (MAP) sensor provides instantaneous manifold pressure information to the engine's Engine Control Module (ECM). The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion. A fuel-injected engine may alternately use a Mass Air Flow (MAF) sensor to detect the intake airflow.

NO POWER TO SPARK PLUG toyota noah 2003 showing error code p0105, p0110, p0115. some one help me plz.


code p0105 refers to manifold absolute pressure (MAP) sensor/ barometric pressure (BARO) sensor--circuit malfunction===causes --wiring---MAP sensor--BARO sensor--ECM
code p0110 refers to intake air temperature (IAT) sensor--circuit malfunction===causes---wiring ---IAT sensor--ECM
code po115 refers to engine coolant temperature (ECT) sensor--circuit malfunction===causes---wiring--ECT sensor---ECM

07 passat code p0642 related to other codes


code p0642 refers to ECM-knock control defective or sensor reference voltage A circuit low or system voltage- malfunction===causes for ecm is ECM--- for voltage A wiring is short to positive --- for system voltage ---wiring--poor connection--battery---alternator
code p2014 refers to intake manifold air control actuator position sensor/ switch bank 1 circuit malfunction=== causes --wiring --intake manifold air control actuator position sensor/switch
code p0106 refers to manifold absolute pressure MAP sensor/barometric pressure sensor-range/performance problem===causes--intake /exhaust leak--wiring--MAP sensor---Baro sensor.
code p0089 refers to fuel pressure regulator --performance problem===causes--fuel pressure regulator--mechanical fault. I would suggest that you have the battery load tested and the alternator checked for correct output as it may be the common reason for the codes .P0089 will not be electrical as it being a mechanical fault then the regulator needs replacing

Engine light on po106 code


  • OBD II P0106

Fault Code Definition
The Manifold Absolute Pressure Sensor/Barometric Pressure Sensor measures the rise and fall of the air pressure inside the Intake Manifold. This provides critical data needed for the Powertrain Control Module (PCM) to control the Air Fuel Ratio, the Ignition Spark Timing, and many components of the Emissions Control Systems. The Manifold Absolute Pressure/Barometric Pressure Sensor P0106 code is set when there is a problematic or erratic performance in the voltage signal to the PCM.

Symptoms

  • Check Engine Light will illuminate
  • In many cases, no abnormal symptoms may be noticed
  • In some cases, the engine may be hard starting and/or get poor fuel economy
  • In some cases, noticeably poor engine performance may occur

Common Problems That Trigger the P0106 Code

  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is defective
  • Intake Manifold vacuum leaks
  • Faulty or corroded Manifold Absolute Pressure Sensor/Barometric Pressure wiring or connections

Common Misdiagnoses

  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real cause is an Intake Manifold vacuum leak
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real cause is a stuck-open EGR Valve
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real problem is a defective Idle Air Control Motor, which causes a very low engine idle

DTC Code P0107


P0107 -- CONTINUOUS
Continuous diagnostic trouble code P0107 indicated barometric pressure out of range low was detected during normal operation.

Possible cause
- faulty internal BARO sensor (PCM)

Perform KOEO On-Demand Self Test.
Is P0107 present?
Yes, REPLACE PCM. CLEAR DTC and RETEST.
No, P0107 is intermittent fault. CLEAR DTC. If DTC reappears, REPLACE PCM.

If you keep getting it, a new PCM is the only fix.

Po108 service code


Hi,
OBD II Fault Code
  • OBD II P0108
Fault Code Definition
The Manifold Absolute Pressure Sensor/Barometric Pressure Sensor measures the rise and fall of the air pressure inside the Intake Manifold. This provides critical data needed for the Power Train Control Module (PCM) to control the Air Fuel Ratio, the Ignition Spark Timing, and many components of the Emissions Control Systems. The Manifold Absolute Pressure/Barometric Pressure Sensor converts the Intake Manifold air pressure into a voltage that is high when the Intake Manifold air pressure is high and low when the Intake Manifold air pressure drops to a vacuum. The P0108 code indicates a high voltage input from the Manifold Absolute Pressure Sensor/Barometric Pressure Sensor to the Power Train Control Module.
Symptoms
  • Check Engine Light will illuminate
  • In many cases, no abnormal symptoms may be noticed
  • In some cases, the engine may be hard starting and/or get poor fuel economy
  • In some cases, noticeably poor engine performance may occur
Common Problems That Trigger the P0108 Code
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is defective
  • Intake Manifold vacuum leaks
  • Faulty or corroded Manifold Absolute Pressure Sensor/Barometric Pressure wiring or connections

  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real cause is a stuck-open EGR Valve
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real problem is a defective Idle Air Control Motor, which causes a very low engine idle
