P0016 2017 GMC Sierra Code - Crankshaft Position - Intake Camshaft Position Not Plausible

Code P0016 indicates a discrepancy between the readings from the crankshaft position sensor and the intake camshaft position sensor, suggesting that the positions are not aligned as expected. This misalignment can affect the engine's timing and performance.

Common symptoms include poor engine performance, rough idling, difficulty starting the engine, and possibly the engine failing to start. The Check Engine Light will also be illuminated.

Potential causes for this code can include a timing belt or chain that has slipped or is worn out, issues with the crankshaft or camshaft position sensors (such as faulty sensors or wiring problems), or the timing components may be damaged or worn.

Diagnosis typically involves verifying the code with an OBD-II scanner, inspecting the timing belt or chain for integrity and correct alignment, checking the crankshaft and camshaft position sensors for faults, and examining all related wiring and connectors for damage.

Repairs can range from replacing the crankshaft or camshaft position sensors, repairing or replacing damaged wiring, to more extensive repairs such as replacing the timing belt or chain and possibly re-timing the engine.

Driving with the P0016 code can lead to further engine damage and potentially unsafe driving conditions. It is advisable to address the issue promptly to avoid more serious problems.

It is quite urgent to address this code because it relates to the engine's timing, which is crucial for proper engine operation and performance. Ignoring it could lead to engine failure.

While a faulty battery itself is unlikely to cause this specific code, poor electrical connections, especially related to the crankshaft or camshaft sensors, can indeed trigger this error. Ensure all connections are secure and free of corrosion.
