The P010E: Mass or Volume Air Flow ‘B’ Circuit Intermittent code indicates that the signal from the mass air flow (MAF) sensor is intermittent, meaning it’s not consistent or steady as it should be. This issue could be caused by an intermittent connection within the MAF sensor circuit, a faulty sensor, wiring or connector issues, or a malfunctioning Powertrain Control Module (PCM). When this code appears, it suggests that the MAF sensor may not be providing reliable readings, which can affect the engine’s air-fuel mixture and performance.
P010E – Quick Overview
| Meaning | P010E: Mass or Volume Air Flow ‘B’ Circuit Intermittent |
| Is it serious? | Yes, this code can be serious as it may cause fluctuations in the air-fuel mixture, leading to unstable engine performance and potential damage. |
| Possible causes | – Intermittent connection in the mass air flow sensor circuit – Faulty mass air flow sensor – Wiring or connector issues – Faulty PCM |
| How to diagnose? | – Inspect the mass air flow sensor for intermittent operation. – Check wiring and connectors for loose or corroded contacts. – Perform a wiggle test to identify intermittent faults. – Replace or repair the sensor or wiring as necessary. |
P010E Meaning
The P010E: Mass or Volume Air Flow ‘B’ Circuit Intermittent code means that the signal from the mass air flow sensor is not steady, causing the engine control system to receive unreliable air flow information. This could be due to an intermittent connection, a faulty sensor, or wiring issues. This code indicates that the air-fuel mixture may fluctuate, potentially leading to performance issues and increased emissions.
Step-by-step diagnostic guide
Follow the outline procedure to diagnose this DTC by eliminating possible causes one by one.
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check if there are any other related codes present. These might give additional clues about the problem. | OBD-II Scanner |
| Inspect Mass Air Flow Sensor | Inspect the mass air flow sensor for any signs of intermittent operation, such as erratic readings. | Multimeter, MAF Sensor Cleaner |
| Inspect Wiring and Connectors | Check the wiring and connectors related to the mass air flow sensor for loose, corroded, or damaged contacts. | Flashlight, Multimeter |
| Perform Wiggle Test | Perform a wiggle test on the wiring harness and connectors to see if any intermittent faults occur. | Multimeter, Diagnostic Tools |
| Repair or Replace Components | If any components, such as the sensor or wiring, are found to be faulty or intermittent, repair or replace them accordingly. | Replacement Parts, Basic Hand Tools |
| Check the PCM | Inspect the PCM for any faults or necessary updates that could be causing intermittent signals from the air flow sensor. | OBD-II Scanner, Multimeter |
| Clear the Code and Test Drive | After completing repairs, clear the P010E code and take the vehicle for a test drive to ensure the issue is resolved. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | After the test drive, re-scan the vehicle to ensure the P010E code has not returned. | OBD-II Scanner |
