Swapped exhaust camshaft position sensor (BMW brand) This is the only code present when I scan. The most suitable way to avoid the P0016 OBD-II code is always to follow the manufacturer’s maintenance recommendations.I have been fighting the P0014 code ("B" Camshaft Position - Timing Over-Advanced or System Performance (Bank 1)) and after trying things I found while searching the forum and Google, I am at a loss. Tips to avoid a P0016 trouble code in future? Only replace it if other checks and repairs have not solved the issue. Replace the camshaft sensor on bank 1 if it’s having intermittent internal problems due to heat or vibrations, as these are not always verifiable.Replace the camshaft OCV for bank 1 exhaust camshaft.Check the timing chain and guides and replace if needed.Repair the wiring or connections to the components, including the camshaft sensor or camshaft OCV.It is recommended to test drive after each check/work is carried out to see if the P0016 code clears. However, if the cause is more severe than this, the following work may be necessary. In some instances, resetting the fault code and performing a road test can solve the issue. By carrying out a pinpoint test, helps avoid misdiagnosis and replacing good components. In many cases, components such as the sensors are quickly replaced when far more common problems are behind a P0016 OBD-II code. When diagnosing the P0016 code, it’s essential to verify the codes and the failure before making any attempt to repair it, including making a visual assessment for possible common issues, including the wiring and connections of the components. Perform the specific manufacturer’s tests for the P0016 trouble code to establish the cause of the code.Instruct the OCV to on and off to see if the camshaft position sensor is alerting timing changes for the bank 1 camshaft.Reset the Check Engine Light and then road test the vehicle to see if the trouble code still exists.Scan engine codes and view the freeze frame data to see when the code was activated.Confirm engine oil is at capacity and that it’s both clean and with the correct viscosity.Make visual checks for issues with the wiring and camshaft and crankshaft sensors, and the oil control valve.The easiest way to diagnose an OBD-II fault code is to use an OBD-II scanner or book a diagnostic check with a trusted mechanic or garage who will: Oil Control Valve (OCV) has a restriction in the OCV filter.The oil flow to the phaser is hampered by an incorrect oil viscosity or partly clogged passages.Mechanical faults such as the timing chain jumped teeth, a slipped reluctor ring on the crankshaft or slipped reluctor ring on bank 1 exhaust camshaft.Defective or corroded wiring or connections.What are the causes of a P0016 OBD-II code? The engine may be hesitant, stall or generally run rough.The engine may be hard to start or have a reduction in power. The following are the most common symptoms: You will likely notice significant issues with the vehicle if a P0016 OBD-II trouble code is activated. What are the common symptoms of a P0016 trouble code? The car is likely to be hard to start, and once running, the engine may be hesitant and stall. Depending on the part that has failed, driving the vehicle for any lengthy period may cause additional internal engine problems. The timing chain may have issues with guides or tensioners, leading to engine damage if the valves hit the pistons. This particular OBD-II trouble code is deemed to be severe as your camshaft and crankshaft aren’t lining up correctly. In addition, the crankshaft position sensor is to be found on the fuel pump on some diesel applications, the flexplate/flywheel, or the crankshaft pulley (or harmonic balancer as it’s also known). On most vehicle applications, the camshaft position sensor is located near the cylinder head so that the CMP is opposite the timing rotor attached to the engine camshaft. Unfortunately, when the signal from either the CMP or CKP sensors is incorrect or defective, the PCM simply can’t efficiently manage engine timing leading to startup problems and idling issues. The CKP relays crankshaft position and engine RPM to the PCM, and again, the data is used by the PCM to control ignition timing and fuel injection. The PCM uses that data to control the fuel injectors for ignition timing to keep cylinders firing efficiently. The CMP relays the information to the vehicle’s Powertrain Control Module (PCM). When a P0016 OBD-II generic code is triggered, it alerts the driver that the camshaft position sensor (CMP) for bank 1, which detects camshaft rotation, is not corresponding to the crankshaft position sensor (CKP) signal.
