With a camshaft position sensor fault, the first step is to get it diagnosed to figure out what is causing the problem. In many cases, there may be no noticeable issues with your vehicle. The vehicle will not start – may be difficult to start.We recommend reading our guide on how much it can cost to replace a defective camshaft position sensor if you’re thinking about hiring a professional. Stretched or misaligned timing components.Defective, corroded, shorted camshaft position sensor circuit connector.Defective, corroded, shorted camshaft position sensor circuit wiring.Damaged or dirty reluctor ring on the camshaft.It is difficult to determine which of these is the source of the problem without specialized knowledge. There are many potential causes of code P0340. When the trouble code P0340 is set, the ignition spark and fuel injector timing fail due to the engine not knowing when to fire these components. The ECM uses this information to control ignition spark and fuel injector timing. It works hand in hand with the reluctor ring that creates a square wave voltage signal that the ECM interprets as the crankshaft position. The camshaft position sensor located in the internal combustion engine monitors the position and rotational speed of the camshaft. It is extremely important to repair code P0340 as soon as possible. It is possible for more damage to occur inside the engine of the vehicle if disregarded for an extended time period. Diagnosis: The vehicle may be difficult to start and the driver may also experience a lack of power when driving.Repair Urgency: Fix this code immediately (same-day if possible) to avoid internal engine damage.Issue Severity: SEVERE – Stop driving immediately.P0340 definition : Camshaft Position Sensor Circuit Malfunction.This problem should not be ignored because eventually the engine will stop working entirely. The latter can be a dangerous situation.Īs soon as you notice your vehicle does not drive like it used to, the Check Engine Light is on, or the vehicle will not start properly, the sensor may need to be replaced. This can happen while the vehicle is parked, or while you are driving. Eventually, the signal will weaken so much the signal will switch off, and so will the engine. As the camshaft position sensor weakens, the signal it transmits to the vehicle's ECM also weakens. If the other problems are ignored, eventually the vehicle will not start. If you ignore the Check Engine Light, it can lead to serious engine problems, such as the engine failing. The mechanic will scan the ECM and see what error codes are being shown to diagnose the problem quickly. Since this light can come on for many different reasons, it is best to have the vehicle thoroughly inspected by a professional. The Check Engine Light will come on once the camshaft position sensor starts to go bad. Of course, these are symptoms for any number of other problems, too. It needs to be completed before the engine cuts out and dies while you are driving, or does not start at all. If you have any of these symptoms, it could mean the camshaft position sensor needs to be replaced by a professional mechanic as soon as possible. If your vehicle idles roughly, stalls frequently, has a drop in engine power, stumbles frequently, has reduced gas mileage, or accelerates slowly, these are all signs your camshaft position sensor could be failing. There are a few warning signs to watch out for before your camshaft position sensor completely fails and shuts down the engine, making replacement a necessity. Over time, the camshaft position sensor can fail, or become worn down, due to accidents or normal wear and tear. Without this information, the engine would not be able to function properly. The ECM uses this data to determine the timing of the ignition, as well as the timing of the fuel injection that the engine requires. The camshaft position sensor gathers information about the vehicle's camshaft speed and sends it to the vehicle's engine control module (ECM).
