2010 Chevrolet Silverado P0016 Code: Diagnosis and Solutions for Camshaft Position Sensor Issue
I'm experiencing a persistent P0016 diagnostic trouble code on my 2010 Chevrolet Silverado with a 5.3L V8 engine. I've already replaced both the crankshaft position sensor (CKP) and camshaft position sensor (CMP), and I've thoroughly inspected all wiring harnesses—no visible damage or faults found. I've also completed the relearn procedures as recommended by the manufacturer, but the P0016 code continues to appear. The issue appears to be related to a timing misalignment between the crankshaft and camshaft, specifically indicating that the CKP and CMP sensors are not detecting Top Dead Center (TDC) simultaneously. I'm seeking further troubleshooting steps or potential causes beyond sensor replacement.
Sorry, this question might be more about getting started than providing answers. Are there any other diagnostic trouble codes present? What specific engine model are you running (e.g., 5.3L)? Have there been any repairs related to the camshaft or timing chain, especially Variable Cam Timing (VCT) system? Is the engine stock—no performance chips, programmers, or modified ECU? In short, the CKP and CMP sensors are not detecting TDC at the same time, which often points to a camshaft being out of sync with the crankshaft.
