P010B OBD Error Code: Problem & Solutions

<<See All OBD Codes

Oftentimes, Engine Warning Light turns up almost immediately it senses the OBD code error. This directly impacts the engine performance as it struggles with power and acceleration as well as failed fuel system causing increased consumption of fuel by the engine.

OBD-II Code Decreased engine performance is defined as a Mass or Volume Air Flow "B" Circuit Range/Performance.

When the engine is running, air passes through the MAF (Mass Air Flow) sensor, which sends a voltage signal to the engine controller. Depending on how much air is passing through the sensor, the voltage varies. The ECU (Engine Control Unit) measures the MAF signal to be within a certain range, depending on RPM and load. If the MAF signal goes outside of this range, higher or lower voltage than expected, the ECU ignores it and sets an OBD Code P010B Error. This OBD code refers to Mass Air Flow (MAF) Circuit Range / Performance.

What causes the problem of Mass or Volume Air Flow “B” Circuit Range / Performance?

• Faulty MAF sensor
• Leakages in Intake Air system
• Mass Air Flow Sensor and Mass Air Filter dirty
• MAF sensor harness open or shorted
• MAF sensor circuit poor electrical connection

1. Mass Air Flow Sensor - If the sensor is unable to measure the air flow pressure correctly, it will hamper the air intake system and fuel delivery system. Replace faulty sensors immediately.
2. Air Intake Kits - Any problem in the intake system affects the fuel air ratio and thus the engine performance. Change to new intake kits now!
3. Air Filters - Check for clogged and damaged air filters and replace them if found so. Buy new air filters form us.
4. Diagnostic Tool - Always use a professional factory grade OBD scanning and testing tools to diagnose the OBD errors. Buy quality tools from us now!

Following are the symptoms indicating OBD code P010B:

 

Common Symptoms

• Check Engine Light On
• Engine running rough and stalling
• Smoke emitting from exhaust tail pipe
• Engine hard starting

Always take help of profession technician to solve the OBD code P010B problem. Diagnosing the problem related to the following components can be the best-case scenario as these components are the first to get damaged for this error.

• Intake Manifold Gasket
• Mass Airflow Sensor

The Related Code is P010B, P010C, P010D and P010E.

The first step is to check for Technical Service Bulletins (TSBs) that apply to your year/make/model/engine, and then do a visual inspection of the wiring and system components. Also take help of an experienced mechanic who used professional diagnostic tools to diagnose this problem. Also, it is important to follow the diagnostic steps properly to avoid any misdiagnosis and stopping the P010B code from returning again. Following are the steps to be followed:

• Inspect all MAF sensor wiring and connectors to make sure they are intact, not frayed, broken, routed too close to ignition wires/coils, relays, motors, etc.
• Check for any obvious air leaks in the air intake system
• Inspect the MAF sensor wires or film to see contaminations such as dirt, dust, oil, etc.
• Carefully clean the MAF and air intake mesh.
• Loss of vacuum to the MAP sensor can trigger this DTC
• A low minimum air rate through the sensor bore may cause this DTC to set at idle or during deceleration. Inspect for any vacuum leaks downstream of the MAF sensor.
• Monitor real-time sensor values from the MAF sensor, O2 sensors, etc. using a scan tool.
• The barometric pressure (BARO) that is used in order to calculate the predicted MAF value is initially based on the MAP sensor at key ON.
• A high resistance on the ground circuit of the MAP sensor can cause this DTC to set.
• Do an exhaust back pressure test to determine if the catalytic converter may be clogged

Common mistakes when diagnosing the P010B code

By far, the most common cause of a P010B being stored is a disconnected MAF sensor. When the air filter is checked or replaced, the MAF sensor is often left disconnected. If your vehicle has recently been service, and a code P010B is suddenly stored, suspect that the MAF sensor has simply been left unplugged.

Some of the common mistakes done while changing diagnosing the OBD code P010B are:

• Intake manifold leakages
• Mass Air Flow (MAF) sensor failure/faulty
• Powertrain Control Module (PCM) failure
• Wiring and Connection issue
