P010B - Mass or Volume Air Flow 'B' Circuit Range/Performance
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 output is incorrect for an undefined reason. The value is likely to be within it’s normal operating parameters but is incorrect 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
