• Causes
• Solutions

The P2016 fault code indicates an issue with the intake manifold runner position sensor or switch circuit on bank 1. This component is crucial for optimizing engine performance by controlling the airflow through the intake manifold. When the circuit voltage is lower than expected, it can trigger the check engine light and affect engine efficiency.

What are the symptoms of the P2016 code?

Common symptoms associated with the P2016 fault code may include:

• Decreased engine performance and efficiency.
• Rough idling or stalling during acceleration.
• Increased fuel consumption.
• Illuminated check engine light on the dashboard.
• In some cases, the vehicle may enter limp mode to protect the engine.

What causes the P2016 code?

The causes of the P2016 code can vary, but typically include:

• A malfunctioning intake manifold runner position sensor.
• Damaged wiring or poor connections within the circuit.
• A faulty engine control module (ECM) that incorrectly interprets sensor readings.
• Intake manifold defects that prevent the proper operation of the runner.

How to fix P2016?

To resolve the P2016 code, the following steps are advisable:

• Inspect the intake manifold runner position sensor for any signs of damage or wear.
• Check wiring and connectors associated with the sensor for continuity, corrosion, or loose connections.
• Replace the faulty sensor or repair any damaged wiring as necessary.
• Clear the fault codes from the ECM and test the vehicle to ensure the issue is resolved.
