P010DMass or Volume Air Flow Sensor B Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- Sensor B is a second mass air flow sensor in a second intake path, found on engines with two air filter boxes – for example the Nissan VR30DDTT twin-turbo V6 (where sensor B belongs to bank 2) or GM's 3.0 litre twin-turbo V6. P010D means the signal of sensor B is above its electrical upper limit – the counterpart of P0103. GM's twin-turbo V6 sets it at 14,500 Hz or more (two trips); Ford's digital sensor B when the signal period drops below 83 microseconds, i.e. above roughly 12 kHz, for 5 s. Typical causes are a signal wire shorted to voltage, failed sensor electronics or interference from nearby ignition or actuator wiring. A substitute value is used.
- What you may notice
- Check engine light on
- Substitute value mode, lack of power
- Rich mixture and higher consumption possible
- Likely causes
- LikelySignal wire of sensor B shorted to voltage
- LikelySensor B electronics failed
- PossibleInterference from harness routing
- RareControl module input faulty
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Easy · Often possible to do yourself.Typical cost: €20 – €350
