Are there 2 camshaft positioning sensors to replace on this car
My check engine light is on and car is running rough error code is 200 1208 cam shaft balancing issue.should I replace the camshaft positioning sensors or is this a deeper issue with balancer. I have read about a class action law suite against mercedes
My car has 102000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
You actually have four camshaft sensors. Two on each head and one for each camshaft. There is likely a deeper issue that should be diagnosed.
1208 is "Constant adjustment of intake camshaft or right cylinder bank in direction retarded."
200 is "(Throttle valve actuator), Position throttle valve."
There is nothing in these codes that suggest there is a balance shaft issue. These codes together could be two separate issues or more than one issue. Only time diagnosing your car will tell. I wouldn’t recommend replacing camshaft sensors without a thorough diagnosis.
The 1200 camshaft code is a cam timing problem. It could be a mechanical problem with the chain or a problem with the system that adjusts the variable valve timing. Variable valve timing system consist of solenoids that advance and retard the camshafts. All manufacturers tend to have issues with these solenoids.
The 200 code has to do with your throttle plate. This could be a TPS (throttle position sensor), throttle valve motor, or a physical problem with the throttle plate itself.
Both of these codes will require a scanner and a technician with experience, like one from YourMechanic, to properly diagnose the trouble codes in your car.
Good luck!
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
You might not have completed the removal and relearning process of the error code. Your car`s ECU might still be coded with the old camshaft position sensor. Your car`s PCM might be faulty. There may be a faulty starter motor causing the issue.
A camshaft sensor determines the exact position of your engine`s camshaft, helping your car keep your engine`s combustion running smoothly. Many modern engines have one camshaft sensor for each camshaft. This can mean up to four, although some cars will only have two.
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.
The code P0016 can be due to the camshaft sensor for bank 1 having an internal intermittent problem due to vibration or heat. These problems may or may not be able to be verified. If repeated attempts to find the failure end up in not verifying the code, then suspect a failing camshaft sensor.
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.
This means that replacing it might require some patience. “name”: “What Happens When A Camshaft Sensor Goes Bad”, Some cars come with four sensors(four-cylinder engine cars, V6 engine cars, and V8 engine cars) whereas other cars come with six sensors(e.g V12 engine cars).
Usually there will only be one crankshaft position sensor. However, there is also a camshaft position sensor as well.
P0335 is a diagnostic trouble code (DTC) for “Crankshaft Position Sensor “A” Circuit Malfunction”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
The camshaft sensor enables the engine control to determine the exact position of the crankshaft drive. This information is required to calculate the ignition point and injection point, among other things.
A P0340 error code indicates a problem with the Camshaft Position Sensor A circuit. It`s possible that the wires leading to the camshaft position sensor are faulty, or that the sensor itself has failed. This error code isn`t a sign of bad camshaft timing.
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.
A P0340 error code indicates a problem with the Camshaft Position Sensor A circuit. It`s possible that the wires leading to the camshaft position sensor are faulty, or that the sensor itself has failed. This error code isn`t a sign of bad camshaft timing.
The main causes may be a damaged timing belt, bad wiring, overheating, crank walks, etc. Some of these also include wear-and-tear, water damage, and oil embedded in the engine, these can also damage the engine`s camshaft since these things will build up over time.

I bought camshaft position sensor off of eBay and car is cutting off a lot. Still has check engine light for camshaft position sensor
ANSWER : 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.
Camshaft Position Sensor
ANSWER : Hello, thanks for writing in about your Dodge Challenger. From what you’ve described it sounds like you may have a different sensor than what the auto parts store has listed. If you go to the dealer you would be able to get the correct one. They use your VIN to get the correct parts. If you need assistance with finding the right sensor or installing it, consider YourMechanic, as a certified technician can come to your home and ensure a correct replacement of your camshaft position sensor.
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.
Can a camshaft position sensor problem masquarade as a timing belt malfunction??
ANSWER : Hi There,
While it may be possible that the motor may have jumped time, this is not likely. It may be much more likely that your issue does in fact relate to a faulty camshaft position sensor as this is one of the main culprits of poor fuel mileage and sluggish running conditions. There are a number of things that can cause poor fuel mileage and a faulty camshaft position sensor is one of them. The camshaft position sensor is a magnetic sensor that monitors camshaft speed to regulate ignition timing and fuel injection timing. It gathers and sends information about the car’s camshaft speed (and as a result the position of each piston) to the car’s electronic control module. This information is received by the computer, which then uses this data to further calculate the time of ignition and the timing of fuel injection required by the engine. When this is not working properly, you may experience a drop in power, poor idling, poor fuel mileage and problems starting the vehicle.
A clogged or dirty EGR valve may also cause poor fuel mileage. The EGR valve is a small component designed to allow the flow of exhaust gases into the intake manifold in controlled amounts. Whenever you start the engine, the valve comes alive and waits in a closed position, blocking the flow of exhaust gases. Once the engine reaches operating temperature and speed increases, the valve, either through vacuum or electronic control will gradually open, allowing burned exhaust gases to enter and combine with the air-fuel mixture inside the combustion chamber. When the EGR valve is clogged or dirty, as they are prone to, it may not function properly causing the engine to idle rough, stall at idle speeds, cause the car to get poor fuel mileage, or emit a strong smell of fuel due to excess hydrocarbons which also results in failing emissions tests.
A clogged or failing catalytic converter can cause the vehicle to have poor fuel economy. As you may already know, the catalytic converter converts toxic exhaust gases into less harmful pollutants that are suitable to be expelled into the atmosphere. When this is clogged, this causes these gases to be backed up into the exhaust system not allowing the engine to breathe properly. When this happens, the engine is forced to work much harder to expel these gases. This often results in the engine bogging down, hesitating, shaking and causing very poor fuel economy. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your vehicle.

Oxygen sensor Bank 2 Sensor 2 for a 2008 ES350. How much to Repair and Replace?
ANSWER : Hi there. The Oxygen sensors are located on the exhaust system in front of the catalytic converter and behind the catalytic converter. You will need to have a Oxygen sensor socket to remove the sensors. The socket is a deep socket with a cut out on it so the harness to the sensor can fit into the slot as you remove the sensor. Make sure that the harness is unplugged before removing the sensor.
Billing question sent to CS for the cost of repair and replace of the Oxygen sensors.
Replaced alternator on car 2 times each time shows it’s charging 14v let car run for a little bit then test drive and car voltage
ANSWER : There are reports that the replacement alternators will not communicate with the engine computer and will not charge correctly. I recommend using only the manufacturer approved replacement part. It can be new or remanufactured but approved for use in the vehicle. Some lower cost alternators on the aftermarket will have charging problems since they will not communicate with the ECM on the vehicle and will stop charging.
