Engine DamageIf the cylinder deactivation system is not working properly, it can cause increased wear and tear on the engine components, potentially leading to engine damage. A technician should diagnose and repair the issue as soon as possible to prevent further damage to the engine.

It is important to have a qualified technician diagnose and repair the P16D0 code on a 2014 Chevy Malibu to ensure that the issue is properly resolved and the vehicle is running safely and efficiently. Ignoring the issue can cause decreased fuel efficiency, engine damage, and potential safety hazards.

P16D0 code on a 2014 Chevy Malibu Description

The P16D0 code on a 2014 Chevy Malibu indicates a problem with the cylinder deactivation system. This system is designed to improve fuel efficiency by deactivating half of the cylinders under light load conditions, such as cruising on the highway.

When the system is active, the engine runs on fewer cylinders, reducing fuel consumption and emissions.

The P16D0 code is triggered when the engine control module (ECM) detects a fault in the circuit that controls the operation of the cylinder deactivation system.

The ECM uses sensors to monitor the oil pressure and position of the lifters, which activate or deactivate the cylinders. If the ECM detects a fault in the system, it will trigger the P16D0 code and illuminate the check engine light.

Possible causes of the P16D0 code include a faulty solenoid valve, wiring issues, failed sensor, or an issue with the ECM. A qualified technician can diagnose the issue using specialized equipment and perform the necessary repairs to restore the proper function of the cylinder deactivation system.

If left unresolved, the P16D0 code can cause decreased fuel efficiency, engine misfires, rough running engine, and potential engine damage. It is important to have the issue diagnosed and repaired as soon as possible to prevent further damage to the engine and ensure that the vehicle is running safely and efficiently.

How much does it cost to diagnose and fix the P16D0 code on Chevy Malibu?
