P2016 code definition

Intake Manifold Runner Position Sensor/Switch Circuit Low Bank 1

What the P2016 code means

P2016 is an OBD-II generic code for the Engine Control Module (ECM) detecting a low voltage failure in the intake manifold runner position sensor/switch circuit, causing the ECM to turn on the Check Engine Light and set the P2016 code.

What causes the P2016 code?

  • The Engine Control Module (ECM) tests the intake manifold runner position on startup to test its operation, and monitors the position during vehicle operation; it will set a fault code P2016 if the signal return voltage is lower than the specified or expected voltage from the sensor.

  • The signal return voltage from the intake manifold runner is low and not within specification.

What are the symptoms of the P2016 code?

  • The Check Engine Light will be illuminated and the code set in ECM memory as a fault.

  • The engine may have low power conditions or acceleration issues, depending on ECM failure management mode for this code.

  • The engine miles per gallon may suffer over time if the intake manifold runner control is disabled..

How does a mechanic diagnose the P2016 code?

  • Scans and documents the codes in the ECM and looks at the freeze frame data for failure

  • Checks the wire connections to the sensor for loose or corroded connections

  • Performs the manufacturer pinpoint test on the sensor to verify the failed sensor

  • Scans the data for the sensor return voltage while wiggling the sensor wiring

  • Disconnects and checks the signal voltage in the connector and tests the sensor for continuity

Common mistakes when diagnosing the P2016 code

  • Clearing ECM memory codes before checking the freeze frame data, so the failure may be duplicated and repaired.

  • Failing to clear the ECM codes after the codes are fixed.

  • Replacing parts when the wiring has been rubbing through from a loose harness tie down.

How serious is the P2016 code?

Code P2016 is a code for the intake manifold runner sensor not working correctly; the problem may not cause major issues with everyday driving except on acceleration. The low voltage output from the sensor may put the vehicle into failure management mode on some vehicles; if this happens, then the vehicle may have reduced power and/or limited systems operation (failure modes vary depending on the manufacturer).

What repairs can fix the P2016 code?

Additional comments for consideration regarding the P2016 code

Code P2016 is to alert you that bank 1 signal is low and will affect the component from working except when the signal is within specifications.
