Many manufacturers (particularly Japanese Automakers) have very strict timing chain service intervals. If you’ve recently changed the timing chain, it may very well have not been aligned properly on install. If it jumps more than a few teeth, the odds are that the engine itself will not run at all.

This will happen when it has stretched or jumped a tooth or two. The timing chain or belt will throw cause P0016 to throw. How to test a crankshaft or camshaft sensor (YouTube) We linked to a great video showing you how to do so directly below. Using a simple voltage tester, you’ll be able to determine whether or not they are functioning correctly. How to Diagnose Vehicle Wiring Problems (AA1 Car)Īfter examining the wiring harness, it would be time to check the sensors themselves. Make sure to check the harness where it plugs into both sensors as well. It’s quick and easy to do this before moving on to the sensors themselves. This is a great place to start diagnosing P0016 in your Opel Astra. A lot of the harness leading to and from the Crank/Cam sensors is going to be exposed to hot exhaust and vibration.

You’ll want to inspect the wiring harness for visible damage. One of the most common causes of P0016 in any vehicle is going to be wiring issues. It’ll either be a wiring issue, or it’ll be a physical problem (bad reluctor or timing chain jumped).

Here are the most common causes of P0016 in the Astra, as well as diagnostic advice, and resources to further explore. Here are the major symptoms of P0016 in the Astra: When this timing is off, the engine will typically not run (or barely run) The crank and cam sensors work in tandem to produce the ideal air/fuel ratio for your engine. P0016 should be considered an important trouble code to diagnose and repair. P0016 refers to which camshaft position sensor is out of time with the Crankshaft. We’ll explore the symptoms and causes directly below. P0016 is know to occur in the Opel Astra when the Crankshaft Position Sensor and the Camshaft Position Sensor are out of alignment by a certain number of degrees, or if there is a sensor issue.
