P010D: Mass or Volume Air Flow Sensor B Circuit High

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.

Symptoms

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

Most likely causes

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

What to check, in order

Start with the simplest. You can tick off each step.

1. Check the air filter and hoses
2. Check the sensor's ground and make sure the signal wire is not receiving voltage from another circuit.
3. Inspect the connector
4. Compare the airflow in live data at idle and while revving
5. Clean the sensor only with a dedicated cleaner
6. Replace the mass air flow sensor if the reading does not follow engine speed

Good to know

• Repair difficulty: easy
• It can trigger limp mode.
• It affects emissions.

What each character of P010D means

• P: Powertrain: engine and transmission
• 0: Generic code: same on every make
• 1: Air and fuel
• 0D: Specific fault in that system

Frequently asked questions

Can I keep driving with code P010D?

You can drive in moderation. If the engine goes into limp mode, go to a repair shop without passing other vehicles or demanding power.

What causes code P010D?

The most common causes are: signal wire of sensor B shorted to voltage; sensor B electronics failed; interference from harness routing.
