What all needs replaced when you change a camshaft position sensor? 2003 Hyundai Sonata
My car will just shut off while driving down the road, it usually starts right back up, but sometimes you have to let it set a few mins. I was just wondering if the timing belt water pump had to be changed when the camshaft position sensor was changed, bc the check engine light code said it was camshaft position sensor
My car has 109000 miles.
My car has an automatic transmission.

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.
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.
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.).
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.
NOT PERFORMING A RELEARN PROCESS
In rare cases the engine may misfire or go into “reduced power” or “limp mode” especially under high RPM/load situations Additionally, omission of the relearn process could cause the vehicle to be unable to pass an emissions test due to incomplete or failed misfire monitor.
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.
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.
Reasons for failure of the camshaft sensor can be: Mechanical damage. Break in the encoder wheel. Internal short circuits.
Definitely don`t submerge the sensor. Cam/Crank sensors are usually hall-effect magnetic sensors that wear over time due to heat. Cleaning them will not commonly make them work any better.
Typically* a cam kit will contain a cam / cams , cam followers , valve springs , a timing disc and cam installation lube . These Kits offer a saving against purchasing the components separately.

They carefully scrutinize each of the given camshaft`s valve timing events and optimize them for the particular engine, application, and specific RPM range, and it is for this reason that the camshaft should be properly degreed as part of the installation process.

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. The Reluctor wheel might be damaged or malfunctioning.

Need to replace Accelerator Pedal Position Sensor
ANSWER : The TPS and a scanner to test it is all that you need. The code P0122 points to the sensor but a through pinpoint test should be done to make sure the sensor is failing before you replace it.
If you need help with this, contact a certified mechanic who can diagnose your Check Engine Light code and make the necessary repairs to your vehicle.
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.
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.
Hi I have a 2004 2.4L automatic Hyundai Sonata. I change the timing belt as it has chewed teeth. I also change the headgasket and
ANSWER : Hi there. Since you completed so many different repairs, it unfortunately opens the door to multiple possible issues that might be the source of your hard to start issue. The first thing I would do is knock off the easy checks; by verifying that all electrical connections, fuel and / or vacuum lines are correctly attached. If everything checks out there, I would either replace the wiring harness to the crankshaft position sensor or check the output from the PCM. Most of the time when crankshaft position sensor issues exist, it’s the wiring harness itself that is faulty. Try those steps and if you still need a hand diagnosing your problem, feel free to contact one of our mobile mechanics and they can come to your location and complete a car is hard to start inspection.

ANSWER : Diagnostic Trouble Codes in the OBD-II regime do not identify faulty parts nor are such codes sufficient, in and of themselves, to condemn specific parts. Although vehicle parts are always referred to in the code descriptions, all that means is the part, component, system, and so forth has to be individually tested in order to figure out exactly what is wrong. Think of the codes as "clues" but clues only. Diagnosis and testing of individual parts is outside of the scope of what a Code Scanner can even do unless you are talking about a very complex factory, bi-directional code scanner which Autozone does not in fact use. So, if Autozone reads a code and insinuates that that Code means that you need part "x" for sure, Autozone is giving you bad advice because they are just guessing and they are guessing with your money. If the camshaft position sensor (CPS) was not actually tested at the shop there is literally no way of their knowing if it is bad or good. They are merely guessing; sometimes they guess right; sometimes they don’t. The timing of the new code’s occurrence, that refers to the No. 6 fuel injector, is quite a coincidence, as it comes immediately after the code that referred to the CPS. I would wonder if in working on the CPS, maybe the mechanic accidentally disconnected the wiring to the injector, to No. 6 in particular. Certainly, that is something to check. With regard to the injector code for No. 6, again, that code does not conclusively mean there is anything wrong with the injector. There could be a corroded wire, loose terminal, cut or disconnected wire or, indeed there are other causes. What you need is an actual diagnostic, one performed by a certified Mechanic who understands the meaning of these trouble codes, their limitations, and how to test individual components. What I would suggest is request a check engine light diagnostic which we already know will require tracking down a particular code and if you do that a certified Mechanic from YourMechanic will get to the root cause of the issue and get this resolved for you. If there is an issue with cylinder no. 6 not firing properly, possibly due to an injector, or injector circuit issue, that would at least partly account for the engine vibration. Any "additional" or "different" vibration coming through the body or steering wheel on braking would have a different cause, for example warped or improperly installed brake rotors. If new brake pads were installed, but the rotors were not turned on a brake lathe or replaced with new rotors, they did the job wrong. Please let us know if you have any additional concerns or questions and if you schedule the check engine light diagnostic, the mechanic will get this resolved for you.
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.
Warning lights and PO344 Camshaft Position Sensor
ANSWER : This vehicle came with three different engines and they all have different directions to replace the sensors. The sensors also may have specialized removal and installation procedures that require special tools for the seals and sensors. The code P0344 is for sensor 1 bank 1 having an intermittent problem that may not involve just the sensor. A long pinpoint test will need to be performed to verify and isolate the failure. I would recommend having a certified mechanic diagnose the problem for you before following through with the replacements of your camshaft and crankshaft position sensors.
