P0016 OBD2 Diagnostic Code on 2007 Dodge Caliber: Camshaft Timing Issue and Symptoms
The check engine light has been on since February 2011 on my 2007 Dodge Caliber. The vehicle runs smoothly and performs well, but the persistent engine light is causing concern. This year, I also noticed that cruise control stopped working unexpectedly. After researching OBD2 code P0016, I found it relates to crankshaft-to-camshaft timing issues. While the symptoms don't seem to directly match typical performance problems, I'm seeking advice on what this could mean and how to address it. I would appreciate any insights into whether this code indicates a mechanical issue or if there are other components involved—such as sensors, solenoids, wiring, or oil pressure. Additionally, knowing the specific engine variant (1.8L, 2.0L, or 2.4L) is critical for accurate diagnosis. Could you recommend scanning the vehicle for diagnostic codes? I'd like to record them, clear the codes, drive under normal conditions, and then report if the light returns or any new symptoms appear?
Since 2011 — that's a long time for this issue to persist. The P0016 code indicates a crankshaft-to-camshaft timing problem, which can affect engine performance. This code specifically relates to the camshaft position and timing mechanism. To assist further, I need to know your exact engine type: 1.8L, 2.0L, or 2.4L. I recommend performing a full OBD2 scan, writing down all detected codes, clearing them, then driving the vehicle under normal conditions. If the check engine light returns or new symptoms appear (like rough idling, stalling, or loss of power), please describe those in detail. This will help pinpoint whether the issue is mechanical, sensor-related, or due to wiring and oil pressure concerns.
