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. P010E covers brief dropouts or jumps in the signal of sensor B without a lasting low or high fault, the counterpart of P0104. Ford's 2020–2023 petrol summary sets it after more than 25 short open or short-circuit events; GM's twin-turbo V6 does not use it, and Ford does not state the trip count. The usual cause is a loose contact at the connector or a chafed wire that opens as the engine moves.

Likely causes

Loose contact at the sensor B connector
Chafed or partly broken wire
Sensor B electronics dropping out
Poor ground or interference

Symptoms

  • Check engine light on, may come and go
  • Occasional hesitation or stumble
  • Intermittent loss of power
