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.

Likely causes

Signal wire of sensor B shorted to voltage
Sensor B electronics failed
Interference from harness routing
Control module input faulty

Symptoms

  • Check engine light on
  • Substitute value mode, lack of power
  • Rich mixture and higher consumption possible

Repair estimate
