What is the P2016 Fault code? What does it mean
Code P2016 stands as “Intake Manifold Fluid Control Position Sensor/Switch Circuit Lower Bank 1”. This code is applicable to all new vehicles and it is general for transmission systems.
The intake manifold flow position sensor (also known by the IMRC valve/sensor), calculates the volume air entering the intake manifold. The flow control valve is controlled by the powertrain controller module (PCM). It controls a flap that opens or closes depending on the engine’s requirements. If the PCM detects a low voltage signal within the flow control valve circuit, the code P2016 is issued. The code description refers to the engine bank in which cylinder 1 is located.
As a second throttle plate, the intake manifold airflow control valve can be referred to as the air intake system’s second throttle plate. It helps optimize the engine’s air fuel ratio (AFR). It can be opened or closed as required to allow air into the engine more quickly or less. The speed at which the air flows is increased can improve the atomization process. This results in more engine power, lower emissions and less fuel consumption.
When a stationary vehicle is slowing down, the flow control valve will open the flaps slightly to allow more air to enter the engine. This will enable the vehicle to accelerate faster. The engine will improve performance by opening the wings as it revs up.
P2016 fault codes can be found on vehicles made by Subaru, Dodge Jeep, Mercedes and Ford.
What is the cause of P2016 Fault code?
Code P2016 does NOT necessarily indicate that the IMRC sensor/valve has failed. It can sometimes be caused by several failed parts. To ensure a proper diagnosis, it is advisable to examine every component of your system. Below are some reasons why fault code P2016 is set:
- – Corroded, damaged, burned, disconnected, or disconnected wiring and/or connectors
- – Dislodged, split, hardened or cracked vacuum lines
- – Defective or excessive carbon contamination of the intake manifold flow control valve
- – IMRC actuator relay failure (if applicable).
- – Defective IMRC valve/sensor
- – PCM-related issues (rarely).
What are the symptoms for the P2016 fault code?
These symptoms may be present if you own a vehicle that has the code “P2016”:
- – Illumination at the check engine lights
- – Increased fuel use
- – Reduced engine performance
- – Engine hesitation during acceleration
- – Misfire-like symptoms
- – Idle fluctuations
How do I fix the P2016 fault code?
When diagnosing this code the PCM will be assumed to have a problem. The PCM is most likely to be defective in this situation. Before concluding that the PCM has a defect, it is recommended to investigate all possible causes.
The following repairs can help resolve the P2016 fault code
- – Replacing the defective intake manifold flow position sensor (Bank 1)
- Repair of damaged wires and connectors.
- Repair of vacuum leaks or leaks in the intake manifold
- – Replacing an IMRC actuator relay that is defective
- – Replacing the defective PCM
How serious is the P2016 Fault Code
A P2016 code indicates that the intake manifold flow position sensor is not functioning properly. Normal driving conditions may not be affected by this fault code, except for acceleration. Some vehicles may be put in fail-safe mode if the sensor is low. This can cause a decrease in vehicle speed and a loss of performance. Avoiding such situations is crucial.
