The test says camshaft, but I put some water in the battery and now work, but not perfect
the gas was low, the light came on and forgot to stop at the gas station. While driving the car started to stalling, then the engine light came on and called AAA. They came and gave me some gas. Then I drove it for a couple of weeks with no problem. Suddenly, the light came back on again and was stalling until one day in the morning stopped working. AAA came with jumper cables and the car worked while it was on, then when turned it off stopped working again so the guy said the problem was the battery. We went to walmart and changed the battery, later on the engine light came back on and took i
Experienced mechanics share their insights in answering this question :
Hi there, thanks for writing in. Your camshaft position sensor is really failing, and needs to be replaced. This sensor can begin to fail for short intervals with heat and vibration, cool off, then work again for a while. Repeat cycle more and more often until total failure as you experience. If you help having this resolved, have a certified professional, like one from YourMechanic, diagnose the stalling issue and replace the camshaft position sensor if necessary.

Hi There, Unfortunately, the flooding or water damage may cause the camshaft position sensor to fail or potentially cause starting or misfiring issues.
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.
The vehicle computer uses the camshaft position (CMP) sensor signal to do a number of things from engine timing to controlling the fuel injectors. Some vehicles determine when to turn on/off the fuel pump with a signal from the CMP sensor signal. So, yes, a faulty sensor can cause exactly what you are experiencing.
Reasons for failure of the camshaft sensor can be: Mechanical damage. Break in the encoder wheel. Internal short circuits.
The more moisture there is in the unit, the more damage it will cause, and the more likely it is that the sensor will turn pink.
Some of the most common sensors that lead to engine stalling include the mass airflow sensor (MAF), engine coolant temperature sensor (ECT) and manifold absolute pressure sesnsor (MAP). The idle air control valve (IAC) and exhaust gas recirculation valve (EGR) are also well known for causing engine stalling.
Car Will Not Start: Over time, as the camshaft position sensor fails, the signal it sends to the engine control module weakens. 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.
When the car eventually starts, the engine will rattle, may make a grinding noise or knocking sound, and the check engine light may remain on. Some drivers have complained that their car starts to go into limp mode. The vehicle may stall or stutter and drivers will have trouble accelerating after coming to a stop.
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.
A broken camshaft is usually caused by a connecting rod or other rotating part coming loose and striking it. Sometimes the cam will break after a short time of use because of a crack or fracture in the cam due to rough handling during shipping or improper handling prior to installation.
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.).
There are a number of reasons your camshaft sensor might break down: grime and oil in the engine, water damage, bad wiring, and overheating can all cause a camshaft sensor to go bad. The biggest thing to do to avoid this is to take care of your car.
Water sensor brick is designed for water detection, which can be widely used in sensing rainfall, water level, and even liquid leakage.
If the engine stalls while idling or driving, the engine may be running out of fuel or not receiving enough fuel pressure to keep it running. The most likely cause of this kind of stalling would be a fuel pump that is not spinning fast enough or is intermittently cutting out.
There are three major causes for a stalled engine: A lack of fuel, a lack of air flow and improper ignition. Running out of fuel is one of the most common causes of engine stalling, but dirty fuel injectors or a plugged fuel filter can also be the culprit.
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.
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.
Will a bad O2 sensor cause rough idle and loss of engine power? You bet. Moreover, you may also notice poor acceleration, engine misfires, and even stalling. Bad oxygen sensors disrupt all kinds of essential engine functions, including engine timing, combustion intervals, and air-fuel ratio.

The failure is usually attributed to one (or more) of the following: insufficient lubrication, improper break-in, reusing old/worn components, mechanical interferences, and inferior hardware/hardware not torqued to spec. Always use the camshaft moly paste that is included with your flat tappet camshaft set.
There are a few things that can cause the crankshaft position sensor to fail, including damage, debris and faulty circuitry. Even for modern electronics, the engine is a violent and destructive environment. Though built for this, most sensors eventually succumb to the ever-present heat and vibrations of the engine.

Water was spilled in the trunk which soaked the car battery. Car won’t start now. Does water destroy a car battery?
ANSWER : Hi, thanks for writing in about the concern with the BMW 320i. If the battery was submerged in water then it’s completely possible for the battery to short out and die. Your friend will need to have the battery replaced. Also be sure to get all of the water out of the trunk. Have a certified technician, like one from YourMechanic, help you guys out if you need assistance with replacing the battery. Good luck.
I have changed battery. I think I put non compatible battery initially and it’s start car alarm loud not turned off with remote ac
ANSWER : As long as the nominal voltage of the battery is 12 volts, it’s compatible. Of course, you need sufficient energy storage capacity, too, which in your case is probably around 850 cold cranking amps. As long as you did not reverse the positive and negative terminals (reverse polarity) when you installed the first battery, the battery is not incompatible. When new batteries are installed, inasmuch as any computer settings are lost, there can appear to be electrical problems, but such are not a fault of the battery. If, for example, you are having problems with the engine immobilizer system (security system) you may see a security warning light on the dash. If the warning light is on, to temporarily override the immobilizer system, see these instructions.
If you are experiencing electrical problems with other components, please simply request an electrical system diagnostic and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
My car ran hot yesterday and I let if cool and put water in it it cranks but it goes dead if I put water in it it stays on
ANSWER : Hi there. In general, when a car overheats it tends to cause excessive steam or hot coolant to spill in the engine compartment. This can cause electrical components to have problems with connections and have difficulty starting. The solution to these common problems is to first determine what is causing the overheating issue initially. You should have a professional mechanic come to your location to complete a car is is overheating inspection to begin the process of diagnosing these problems.
New battery, windows not working, dashboard lights on, radio not working, and the car isnt cranking. No noise.
ANSWER : Hi there:
Usually if one accessory is working after installing a new battery, but select ones are not, it’s not related to the battery itself. It may be an issue with battery cables that are worn out, the main relay or other electrical problems that may have been caused by incorrectly installing the battery perhaps or previous damage occurring before the battery was replaced. However, blemish battery’s are not that reliable and tend to have issues holding a charge. The items you listed as not working are controlled by accessory switches, so it’s possible that these components are faulty. Due to the complexity of trying to diagnose this issue, you might want to have one of our mobile mechanics come to your location and complete a car is hard to start inspection first; so they can pinpoint the source of the issues you’re having and recommend the right repairs be completed.
Battery is not charging properly
ANSWER : Hi There,
What you are describing is most likely a faulty alternator. The alternator charges the battery while the engine runs by generating amperage and recharging the battery while the engine turns the alternator pulley. The voltage regulator is a unit that regulates the charging of the battery by the alternator and maintaining a certain amperage while the engine runs. When the alternator is not working properly, this may result in the battery quickly losing charge and the car losing all power. You may also notice a whining sound as a result of the bearings inside the alternator begin to fail. I would recommend having an expert from YourMechanic come to your location to diagnose and inspect your charging system.

My car will not start I got a new stater, battery and alternate. It work for a minute then stop and now it’s saying battery saver
ANSWER : Hello, and thank you for writing in. The battery saver mode is a function that attempts to cut various components that need a power supply while the vehicle is off. It goes into effect when the power supply to the battery is low and it is trying to save enough to start the vehicle. Both of the battery saver mode and the sounds you are hearing when trying to start, are both signs of a weak battery. You may want to jump start the car or charge the battery. Make sure that your battery cables and the ground connection are all clean, dry, and tight. Also make sure the new alternator and starter connections are in the same stable condition.

Battery light stays on and overnight battery drain. 2006 Land Rover LR3
ANSWER : Hi there – yes, something is going on here that’s draining your battery. Perhaps the pressure of the engine wash dislodged wiring which has shorted, or there was a chemical reaction to the cleaning solution that caused electrical damage in the alternator or voltage regulator. These componnents can be checked off of the vehicle. Vehicle wiring can be diagnosed by connecting an ammeter to the positive (red) battery cable, observe the current drain (likely less than 1 amp), then, one at a time, remove each fuse, check to see if the current drain has dropped to near 0, then reinsert the fuse. This process should identify the faulty circuit in most cases. The specific components on that circuit can then be checked for current drain problems. A professional mechanic, like YourMechanic, can come to your location, and perform this procedure for you, and replace/repair the failing component.
