Error Code P010C: What It Means & What To Do?

<<See All OBD Codes

Is your car engine stalling and not starting? Is there an increase in the fuel consumption? Have you lost the response from the engine with sudden downfall in acceleration? All these can be an indication towards OBD Code P010C.

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

OBD Code P010C means that the Powertrain Control Module (PCM) is detecting contradictory readings from the Manifold Absolute Pressure (MAP) Sensor in relation to the voltage range it should project.

The Manifold Absolute Pressure (MAP) Sensor tells the engine control module (PCM) how much pressure is in the engine manifold. This P010C diagnostic trouble code (DTC) means that there is a low condition detected in the Mass Air Flow (MAF) B sensor or circuit. The PCM detects that the actual MAF sensor frequency signal is not performing within the normal expected range of the calculated MAF value.

What causes the problem of Mass or Volume Air Flow “B” Circuit Low?

• Damaged/faulty MAF sensor
• Faulty MAP sensor
• Faulty wirings and connectors of the sensors
• Obstruction in air flow
• Dirty Air Filter
• Defective Electronic Throttle Body
• Obstruction in hose from intake manifold to MAP sensor
• Vacuum leakage in the intake manifold, air induction system, or throttle body
• Damaged/Loose electrical connection related to the sensor and circuit

1. Mass Air Flow Sensor - Check for faulty/damaged sensor along with the wiring and connections associated with it. Replace faulty MAF sensors now!
2. Air Intake Kits - Inspect the problem for leaky air flow hoses and other damages to the intake system. Replace faulty intake components with us!
3. Air Filters - Any problem with filters will result in reduced flow of air as well as particulate matter entering the engine along with the fuel that can hamper the engine performance.
4. Diagnostic Tool - You will need high grade diagnostic tools for correction of the OBD error code which is detected. Buy now to grab amazing deals.

It is important to notice the probable symptoms which can indicate towards the problem of MAF “B” Circuit Low performance issue. Following are the common symptoms of OBD Code P010C Error.

Common Symptoms

• Check Engine Light illumination on dashboard
• Rough Engine Idles
• Engine surging and detonation
• Reduces Acceleration and Throttle response
• Loss of Engine Power
• Engine stalling and not starting

• Intake Manifold Gasket Replacement
• Mass Airflow Sensor Replacement

At Parts Avatar Canada, find the best quality replacement and performance parts at the best price in the market to correctly diagnose the OBD Code P010C error.

A qualified mechanics may need to conduct specific diagnostic steps, depending on the make and model of the vehicle. Also, mechanics uses other tools and testing equipment, such as the volt-ohmmeter, carburettor cleaner can, meter’s wire-piercing probe and an intake cleaner can.

• Check for damaged or broken wirings and connections in relation to the sensors and circuits.
• Check the air cleaner element and look for any signs of clamps or leaking in the pipe starting from the MAF to the Throttle body.
• Then, check the vacuum lines in intake manifold for any cracks, obstructions, or looseness, as these can cause vacuum loss.
• Detach every sensor and check the connector for signs of corrosion and bent pins that are pushed out.
• 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.
• Use a scan tool to monitor real-time sensor values from the MAF sensor, O2 sensors, etc. and check for Technical Service Bulletins (TSBs) for your particular make/model in case of known issues on your vehicle.
• 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.
• Replace the MAF sensor, if a high resistance on the ground circuit of the MAP sensor is detected.
• Also check for any faults in the PCM and replace/reprogram it as necessary. Although this problem is rare but if all the other components are fine, then the check is necessary.

Common mistakes when diagnosing the P010C code

Common mistakes when diagnosing the P010C code include;

• Replacing Mass Air Flow Sensor without thorough examination
• Replacing one or more sensors without testing their functionality prior to the replacement.
• Not checking the wiring and connectors for damages
• Replacing PCM, without checking other components for errors
