This is only a temporary solution and the problem will reappear so replacement of the sensor is necessary as a permanent fix. A faulty VVT solenoid can cause several problems. This sensor goes bad on me alot so I just domt drive it past 3000 rpms to be safe. Our technicians tell us the engine oil should be checked to make sure it is clean and at the proper level before replacing any parts to correct this concern. A camshaft actuator solenoid--normally installed in the front of each cylinder head -- is used to precisely control the flow of oil into the camshaft actuator.This changes the rotation of the camshaft to adjust valve timing and valve overlap on the go. Certain models of cars with a bad camshaft position sensor will end up with a locked transmission that stays stuck in a single gear. The mechanic has checked the gear and certified it OK. Common Symptoms of a Faulty Camshaft Position Sensor #1 – Check Engine Light Illuminates When your camshaft position sensor is faulty or starts having issues, the first thing you should notice is that your “Check Engine” light comes on in your dashboard. This only happens when the engine is cold. Please do not ignore or postpone scanning your vehicle or getting it inspected when your Check Engine light turns on or else your engine could end up getting seriously damaged. These solenoids are used to control both exhaust and intake camshafts, creating the possibility of lower … "Check Engine" Light. The end result is variable valve timing that improves engine performance, fuel economy and a reduction in emissions. Next try the wiggle test to see if the condition improves or worsens when you physically move the wiring harness around. As oil goes through an engine, over time, the combination of heat and small impurities cause the oil to thicken. I have a 2017 Elantra that has been dying when I slow to a stop, code showed bad camshaft sensors, replaced both lights went off but it is still doing it. It will run fine without it. P1397 – camshaft position sensor circuit (this can be caused by a faulty sensor. The replacement for the camshaft … The most common symptoms of a bad Variable Valve Timing (VVT) solenoid are check engine light, engine performance, rough idle, and increased fuel consumption. It sounded to me like they were trying to sell the battery saver. How are your spark plugs? With everything going on in the world right now we are just trying to make it to work. Old sensor showed ‘melt’ on that end, was tight to remove. A long coil of wire wrapped several times, called a solenoid, controls the amount of oil pressure that is applied. Here are a few symptoms of a worn out or broken VVT solenoid. The Check Engine Light will come on once the camshaft position sensor starts to go bad. Since today's modern cars are controlled by an Engine Control Unit (ECU), virtually all individual components are monitored by the ECU. A bad camshaft position actuator solenoid valve control circuit often comes with symptoms that you should never ignore or prolong. Without the code there’s no way I can even guess at what that problem could be. The end result is variable valve timing that improves engine performance, fuel economy and a reduction in emissions. 1) Ignition Issues The mixture of air and fuel in the internal combustion engine requires a spark in order for the ignition to take place. Check the wiring around the cam sensor if you can. If the engine can’t detect the camshaft position, it won’t be able to start. I am not sure if I should trust Auto Zone’s machine per the mechanic. As already mentioned, the main purposes of variable valve timing is to make sure that the valves open and close at the right time to boost engine performance as well as to reduce the consumption of fuel.
