P2016: Intake manifold runner position sensor circuit low (bank 1)

What P2016 means

The position sensor tells the ECU where the intake manifold runner flaps are by means of a voltage. Here that voltage is below the possible range, which points to an electrical problem (wiring, connector, earth or the sensor) rather than the actual flap position.

Most common causes

• Loose or corroded position sensor connector
• Signal wire shorted to earth or broken
• Missing sensor reference supply (usually 5 volts)
• Faulty position sensor
• Engine ECU fault (rare)

Symptoms

• Engine warning light on
• Possible slight loss of power
• Sometimes no symptoms

Can you drive with P2016?

Yes, no rush You can keep using the car normally and fix it without rushing; at most it will perform slightly less well.

How to check it

If your scanner shows the flap position live and it reads zero or near zero all the time, suspect the wiring or the supply. Check the connector before replacing parts.

How to read and clear P2016 with Final OBD

Plug an OBD2 scanner in under the steering wheel, switch the ignition on and open Final OBD. Under Faults you’ll see P2016 with this same explanation and whether it’s confirmed, pending or permanent.

With Free you read this code with its short description for nothing, and clear it if the engine stores it over standard OBD. With Pro you get the full explanation, how the car was running when it was logged (revs, temperature, load) and clearing in every control unit.

Clearing the code only turns the light off: if the cause is still there, it comes back. Clear it once it’s fixed, and not right before the ITV. It’s all in how to read and clear fault codes and in the ITV and OBD.
