P010F OBD Error Code: Problem & Solutions

<<See All OBD Codes

A direct impact on the air intake system can cause immediate loss of power form the engine due to multiple reasons of malfunction and directly impacting the amount of oxygenated air entering the engine for combustion. Any mismatch in the fuel to air ration will directly result in loss of power form the engine and record P010F error code in the PCM after detection of the problem.

OBD-II Code Decreased engine performance is defined as a Mass or Volume Air Flow Sensor A/B Correlation.

When a code P010F is stored, it means that the powertrain control module (PCM) has detected a malfunction with the mass air flow (MAF) or volume air flow (VAF) system. The use of code P010F is limited to vehicles which are equipped with multiple throttle bodies or intake air inlet sources that require multiple MAF/VAF sensors.

A P010F relates to a comparison between the separate MAF/VAF sensors. A strong vacuum is created when the internal combustion engine is in operation. This vacuum draws in needed air to complete the combustion process. This air is regulated by the throttle plate under acceleration and the idle air control (IAC) valve when the engine is at idle. One of the most critical factors in the optimization of fuel efficiency and minimization of harmful exhaust emissions in mass produced automobiles is achieving a correct fuel to air ratio. The air entering the intake is measured using the MAF or VAF sensor/s. Fuel delivery and ignition timing strategy is calculated by the PCM using data collected from the MAF/VAF sensors. The air which passes through these devices is referred to as metered air. Air which is involuntarily introduced to the engine can contribute to excessively lean i.e., too much air or not enough fuel conditions which is called “unmetered air”.

When multiple MAF/VAF sensors are used in conjunction with each other, the PCM compares data between the two in order to ensure that a similar conclusion is derived. If the degree of air flow or sensor voltage varies by more than a pre-programmed amount, a code P010F will be stored and a malfunction indicator lamp (MIL) may be illuminated.

What causes the problem of Mass or Volume Air Flow Sensor A/B Correlation?

• Mass Air Flow sensor faulty
• Intake air hoses leaks
• Mass Air Flow Sensor dirty/contaminated
• Mass Air Filter dirty/clogged
• Open or shorted Mass Air Flow sensor harness
• Poor electrical connections to the MAF sensor circuit

1. Engine Control Module - Always check for faulty ECM components and replace as it can cause wrong OBD error to flash. Replace now!
2. Powertrain Control Module - Faulty PCM will apprehend the data wrongly and cause the problems with the fuel delivery and air intake systems respectively. Replace faulty components now!
3. Diagnostic Tool - Take help of an experienced mechanic and use professional diagnostic tools to solve the problem. Buy quality tools now!
4. Auto Switches & Sensors - Check foe defective switches and sensors and replace if found faulty.
5. Air Temperature Sensor - If the sensor doesn’t work properly, it will not be able to track the air entering the system properly and will lead to wrong fuel to air ratios as well. Thus, check for faults and replace accordingly.
6. Air Intake Kits - Always check for problems in the air intake system to maintain the proper air to fuel ratio and enable proper functioning of the engine. Buy quality air intake kits from us.
7. Air Flow Sensor Connector - Replace faulty connectors as they will affect the air intake systems and will hamper the engine performance as well. Replace damaged connectors now!
8. FVR Wiring/Harness - Check for damaged and faulty wiring in connection to the sensor and circuits. Thus, repair and replace immediately.

Since this code is likely points to the problem on the MAF circuit, there may not be any noticeable big symptoms at present and even if there are any can we considered as general problems by the driver. However, the MIL will likely be on and the car may exhibit some drivability problems.

Common Symptoms

• Check Engine Light will illuminate indicating error P010F code by the PCM
• Engine lacks power and reduces performance and acceleration
• Increased fuel consumption due to problem in fuel delivery system
• Unusual throttle response and stalling
• Lean or rich exhaust

• Replacement of Intake Manifold Gasket
• Replacement of Mass Airflow Sensor

• A suitable OBD-II scanner (or code reader) and a digital volt/ohmmeter will be most helpful in performing a successful diagnosis.
• Begin with a visual inspection of all wiring and connectors and repair or replace damaged, disconnected, shorted, or corroded wiring, connectors, and components as necessary.
• Always retest the system after repairs are completed to ensure success. If all system wiring, connectors, and components (Including fuses) appear to be in normal working order, connect the scanner (or code reader) to the diagnostic connector and record all stored codes and freeze frame data.
• Continue by clearing the code and operating the vehicle to see if it returns. This will help to determine whether or not the malfunction is intermittent.
• Test drive the vehicle afterwards to ensure that a successful repair was performed. If the MAF sensor confirms to the manufacturer’s specifications, prepare to test system circuits for resistance and continuity by disconnecting the electrical connector/s from all related control modules (especially the PCM).
• Compare your actual findings with manufacturer’s specifications and repair or replace circuits, components, or connectors as required
• Once the repairs are made, clear the codes and test drive the vehicle to ensure that the repair was successful. If the MAF sensor and system circuits are comparable to the manufacturer’s specs, suspect a defective PCM (or another related controller).

Common Mistakes When Diagnosing The P010F Code

Some of the common mistakes done while changing diagnosing the OBD code P010F are:

• Improper assessment of the MAF sensor failure
• Simply replacing the Powertrain Control Module (PCM) without considering other possibilities of problem.
• Not noticing the damaged or loosened wiring and circuit problems.
