I bought camshaft position sensor off of eBay and car is cutting off a lot. Still has check engine light for camshaft position sensor. Do you think the part from eBay is bad?
My car has 190000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Hello, thanks for writing in. From my experience with eBay sensors, chances are that it is bad. This happens all of the time with these sensors. A bad crank position sensor can also cause this as well as a failing timing chain. I usually install a computer scan tool to be able to see which codes are coming up and which readings look like they are off. If you would like help, consider having an expert automotive technician from YourMechanic come to your home or office to inspect and diagnose this issue for you, and make or suggest any repairs as needed.
How to Identify and Fix Common car Problems ?

A failing camshaft position sensor begins losing its ability to quickly transfer data. Mismatched fuel delivery and ignition timing, even if off by a few milliseconds, will cause your vehicle to sputter, accelerate poorly, lack power, stall or even shut off.
Unfortunately, there`s no way to reset a camshaft position sensor. If you`re having camshaft issues (check engine light on, acceleration trouble, sputtering and stalling, etc.), you`ll have to replace the part entirely.
In most cases, a faulty camshaft position sensor will cause a vehicle`s check engine light to illuminate. This occurs when one or more timing-related diagnostic trouble codes are logged by a vehicle`s PCM.
your engine isn`t running well: the signal from this sensor is required to operate the fuel injectors, as well as most timing-based engine functions, like spark control. because of this, a faulty sensor can easily cause a misfire, poor acceleration or other problems.
Yes. You can just unplug it. Car will run fine, but will require multiple tries to start.
The most common failure is the crankshaft position sensor. These fail much more frequently than the cam sensor and will cause a no start. It can also occur if the timing belt broke or jumped a tooth. I would do a compression test also to see if there is low compression.
While the new sensor is now installed, and you may get lucky and have it function perfectly right from the start, it`s highly recommended to “relearn” the sensor at this point in order to calibrate the entire system properly.
Reasons for failure of the camshaft sensor can be: Mechanical damage. Break in the encoder wheel. Internal short circuits.
When the engine no longer receives the signal, you will not be able to start your car. Engine Misfires: A failing camshaft position sensor can cause your engine to misfire. Transmission Shifting Problems: The data sent to the engine control module can stop the transmission from shifting properly.
Error code P0340 indicates a malfunction with the camshaft position sensor A circuit. This type of malfunction can cause serious issues that require immediate repair because the underlying cause of the code could damage your vehicle`s engine if you continue to drive it.
If the engine timing of the cam is off, your car will either be running rough or not at all.
What happens if you drive without a crankshaft sensor? Your car`s engine will not function correctly if you do not have a crankshaft sensor.
How to reset the camshaft position sensor? Evidently, you cannot reset a camshaft position sensor. Therefore, you will need to replace the component if your camshaft malfunctions (check engine light on, acceleration issues, sputtering and stalling, etc.).
Bad Sensors
One common culprit for this problem is the crankshaft position sensor, which measures the position and speed of the crankshaft. The computer uses the information from this sensor to know when to fire the spark plugs. If the sensor isn`t working, the spark plugs won`t fire, keeping the engine from starting.
After you`ve replaced the camshaft sensor, be sure to take your car to a qualified mechanic and ask them to reprogram it using a OBD-II scanner. Doing so will clear any error codes and make sure that the engine computer is getting accurate signals from the new sensor.
You don`t need to reset it, once the engine turns over it will send the information to the ECM and the ECM will be ready to start the engine.
Once you install your new camshaft, you may need to go through a break-in procedure, depending on what the manufacturer recommends. This can be quite an extensive job for some vehicles – and if you do it incorrectly, engine damage can occur.
When a camshaft is replaced, it is common to replace the camshaft timing components such as the tensioner, timing chain or belt, and sprockets as well. If your engine has a water pump that is driven by the timing chain, that too will be recommended for replacement.

The computer uses the information from this sensor to know when to fire the spark plugs. If the sensor isn`t working, the spark plugs won`t fire, keeping the engine from starting.
Intermittent Stalling
If the crankshaft position sensor or its wiring have any issues, it can cause the crankshaft signal to be cut off while the engine is running, which can cause the engine to stall. This is usually a sign of a wiring problem. However, a bad crankshaft position sensor can also produce this symptom.
Engine stalling
Your engine may stall when you have a defective crankshaft position sensor. If you don`t replace this sensor soon, your engine won`t run. The only option will be to have your car towed to a shop so that you can replace the sensor.

Venza 2010 L4-2.7L: My check engine light is permanently turned On. I have these codes P0012, P0016, P0017. What needs to be fixe
ANSWER : These are fault codes indicating problems related to the timing of your car’s engine. Normally the car will not run very well or sometimes not at all when these are on. I would suggest having an expert from YourMechanic come to your home to diagnose these trouble codes and potentially reset them to see if they register again. There are also sensors related to the exhaust as well. There is what is called an oxygen sensor which relays information to the car’s computer regarding the content of the exhaust gases which then tells the computer how to adjust the air/fuel mixture.
I have a 96 Ford ranger with cel p0340 I have recently done a timing belt, engine runs great replaced cmp sensor cel still on
ANSWER : Hi There,
This may happen for a couple of reasons. First, check to be sure that the connections to the sensor are clean and not faulty or broken. Secondly, check to be sure you replaced the correct sensor as there are two camshaft position sensors in some applications. If you need further help with this, please reach out to us here at YourMechanic as we are always here to help.

check engine light O2 sensor already replaced same codes still popping up after replacing old O2 sensor
ANSWER : Hi there. What you received from the parts store was a code retrieval, not a diagnostic. The codes are set when a fault is detected against normal operating parameter. The computer does not know what caused the fault, only that the fault meets the criteria for this code to set. There could be a problem in the wire harness, converter, or the ECM. The code and data are needed to properly assess the direction that a diagnosis needs. I strongly suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a check engine light inspection.
CHECK ENGINE LIGHT ON
ANSWER : The on board diagnostic (OBD) sets a pending code each time the ECU detects a problem. It confirms the code if it sees the same problem twice. So you’re really only dealing with the two codes : P0016 and 17.These codes are telling you that the timing between the crankshaft and the camshaft are off on Bank 1 (the driver’s side) cylinder bank. This could be a sensor error, a problem in the reluctor ring on the harmonic balancer, or a timing chain problem. Without doing a thorough diagnosis, it’s impossible to say what parts specifically need to be replaced. If you contact Your Mechanic, they can send a technician to your home or office to investigate the codes on you Mercedes and then let you know what it will take to fix it.
Car won’t start. The check engine light, battery light, and oil change light are coming on. I tried jumping the car and nothing happened. Why won’t my car start?
ANSWER : Hi and thanks for contacting Your Mechanic. If sometimes your vehicle will start with the new alternator and sometimes it won’t, then there is a loose connection in your charging system. Check all of the wires to the alternator and to the battery. Make sure that the battery cables are clean and tight. Make sure that the wires to the starter are clean and tight. A loose ground to the ignition system will cause the vehicle to not crank over. Check all of the ground wires from the battery to the starter. Make sure that they are clean and tight. If you need further assistance troubleshooting your no start situation, then seek out a technician, such as one from Your Mechanic, that can assist you.
Check engine light refuses to go off after engine replaced
ANSWER : Hello there, you have a long series of issues going on with your 2013 Hyundai Sonata. If you keep getting a repeating oil light on than there is likely a fault in that system.
Since this fault has lasted after the engine was replaced it could be a oil pressure sensor, wiring harness fault, ECU fault, oil pump, oil strainer clogged, or low oil pressure.
To diagnose this issue properly you need a complete vehicle inspection to start from square one and identify the root cause of all this.
Car started to slow down and then the check engine light, battery, and engine oil light came on. What could cause this?
ANSWER : Hi there. It is possible that the battery cable came loose or the wires to the oil pressure sensor has came loose or failed. Check the battery cables and make sure that the terminals are tight and clean. Check the wires to the oil pressure sensor and make sure that they are connected and not broken. If everything looks good, then the oil pressure sensor may have failed. Plus, check the computer for codes and see what is stored. This will lead you to the part that could have failed. I recommend replacing the oil pressure sensor then checking to see if the lights will go out. If you need further assistance troubleshooting your vehicle, then seek out a technician, such as one from Your Mechanic, that can assist you with the warning lights that came on.
