What if the service information, the wiring diagram, the scan tool, and even AI were all pointing you toward the wrong part — and you had no idea? That is exactly the trap that catches DIYers and even seasoned techs every single day, and it costs real money in wrong parts, wasted hours, and frustrating comebacks.
Here is the painful reality: when a camshaft position sensor code like P0365 shows up, most people do what makes sense — they look up the code, trust the service data, buy the part it points to, and replace it. Then the light comes back. So they replace another part. Then another. Sound familiar? The customer in this video had already thrown parts at his 2013 Dodge Avenger before he ever walked through the shop door, and he was still no closer to a fix. The problem was not his willingness to do the work. The problem was that the information he trusted was flat-out wrong.
Imagine instead walking through a diagnosis where you verify every assumption before spending a single dollar on parts. Imagine unplugging a sensor, reading the code it generates, and knowing with certainty which sensor the computer actually considers bank one sensor two — regardless of what any diagram says. Imagine handing your customer a clear explanation of exactly what was wrong, why the previous parts did not fix it, and what the correct repair is. That is the confidence this checklist gives you.
Eric O at South Main Auto has built one of the most respected automotive diagnostic channels on YouTube by doing exactly this — following the data, never the assumption. In this real-world case on a 2.4L Dodge Avenger with dual VVT, he caught a mislabeled sensor in the OEM wiring diagram, confirmed it live with a scan tool, and resolved the fault with a single correct sensor swap. His process is methodical, honest, and repeatable — and now it is yours in checklist form.
This PDF checklist walks you through every step Eric used: documenting the initial condition, pulling and interpreting codes, cross-referencing wire colors, using the unplug-and-read method to physically verify sensor identity, evaluating repair options for your customer or yourself, selecting the right replacement sensor, and confirming a complete drive cycle with no pending codes. Stop guessing. Stop trusting sources that have not been verified. Grab this checklist and diagnose cam sensor faults the right way the first time.
Every checklist item comes with actionable notes to guide you — things like "Don't forget to do this before you start," "Avoid this common mistake," or "Set a reminder for 30 days out." Nothing vague, just clear next steps.
