P010D - Mass or Volume Air Flow 'B' Circuit High
Mass / Volume Air Flow sensors are used to provide the ECM with information on the amount of air entering the engine. This information can be used for fueling and emissions control.
Fault Code Explained
The ECM has detected the sensor value is above it’s maximum parameter or is higher than expected for the current operating conditions
There are a variety of different sensor types depending on system. It is recommended to follow the manufacturers test plan to diagnose this fault code.
General recommended tests
- Test sensor supply Voltage and Earth
- Test sensor output signal
