Component Location
This video focuses specifically on showing you the exact location of the four camshaft position sensors on the longitudinal 3.6L Pentastar V6 engine. Because the Chrysler 300 uses a rear-wheel-drive layout, tracking these sensors is different from front-wheel-drive platforms. This dual-overhead-cam (DOHC) engine utilizes a total of four sensors—two for Bank 1 (the passenger side bank, cylinders 1-3-5) and two for Bank 2 (the driver’s side bank, cylinders 2-4-6). Each bank has an individual sensor for its respective intake and exhaust camshaft, mounted directly through the rear side of the cylinder head valve covers, facing toward the vehicle’s firewall. This visual guide is designed to show you precisely where to look under the hood so you can isolate and locate each sensor without any guesswork.
DIY Repair Benefits
Locating the specific Bank 1 or Bank 2 camshaft position sensors is the crucial first step if you are planning a DIY vehicle inspection, sensor replacement, or diagnostic process. Knowing their exact positions allows you to narrow down which sensor is faulty based on your scanner data, inspect the individual three-pin electrical connectors for corrosion, check the wiring harness for heat damage near the back of the engine bay, and handle your automotive project efficiently, saving you both time and a costly trip to the repair shop.
Bad Camshaft Position Sensor Symptoms
A malfunctioning camshaft position sensor disrupts the powertrain control module’s ignition and fuel injection timing synchronization. Common symptoms of a failing sensor on this 3.6L engine include engine misfires, a rough or erratic idle, sudden engine stalling while idling or driving, a noticeable drop in fuel economy, a “hard start” or extended cranking condition before the engine fires up, and a triggered Check Engine Light with stored timing-specific trouble codes (such as P0340, P0344, P0345, P0349, P0365, or P0390).
Safety First
Working near the top-end valvetrain components and around tight spaces near the firewall requires proper safety precautions. Always make sure the engine is completely cool, the ignition is turned off, and the negative battery terminal (located in the trunk on the Chrysler 300) is disconnected before beginning your inspection to avoid electrical arcs, short circuits, or contact with hot engine surfaces. Wear appropriate safety glasses and protective gloves, use care when releasing the fragile plastic locking tabs on the electrical connectors, and remain highly attentive to your surroundings to prevent any accidental injuries.
