Knock Sensors Bank 1,2 Camshaft Position Sensor Kia Sorento 3.5L 2011-2015 Location and Replacement

Component Location Overview

In this video, I provide a clear and direct look at the exact locations of the Bank 1 and Bank 2 knock sensors, as well as the intake and exhaust camshaft position sensors for the 2011-2015 Kia Sorento with the 3.5L V6 engine. On this V6 platform, the knock sensors are positioned in the deep “valley” of the engine block, while the camshaft position sensors are mounted on the cylinder heads. This visual guide is essential for identifying these distinct components and planning the necessary access to perform a successful repair.

Benefits for DIY Repairs

By documenting these sensors in one comprehensive guide, you can tackle complex diagnostic issues related to engine timing and detonation simultaneously. Having a clear visual reference for these specific locations—especially the buried knock sensors—allows you to plan your disassembly path effectively, reducing the time your engine remains exposed and ensuring you can complete these involved repairs with professional-level confidence.

Common Symptoms of Failure

Issues with these sensors often trigger performance-related trouble codes on the 3.5L Sorento:

• Knock Sensors: You will typically see DTCs related to circuit performance. Symptoms include a noticeable loss of power, reduced fuel economy, and audible pinging under load, as the ECU pulls timing to protect the engine.
• Camshaft Position Sensors: These often result in hard starting, engine misfires, hesitant acceleration, and an unstable, rough idle. The Engine Control Module relies on these signals to synchronize ignition and fuel injection accurately.

Safety Precautions

Working deep within the engine or on multiple sensor systems requires disciplined safety protocols:

• Intake Port Protection: When accessing the knock sensors, the intake manifold must be removed. Once it is off, immediately cover the exposed cylinder head intake ports with clean, lint-free rags or tape. This is vital to prevent debris or dropped hardware from entering the combustion chambers.
• Fuel System Safety: You will be working near the fuel rail. Ensure the engine is completely cold, keep the area well-ventilated, and have a fire extinguisher nearby.
• Electrical Care: Always ensure the ignition is in the “off” position and the battery is disconnected before performing any work on the engine’s sensor harness.
• Protective Gear: Wear safety glasses to protect against falling grime and gloves to shield your hands from sharp edges and hot components.
