How to Identify and Fix Common car Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced mechanics :

MALFUNCTION INDICATOR LAMP: If the malfunction indicator lamp comes on and stays on while the engine is running, this indicates that there is an OBD ll problem and service is required. AIRBAG READINESS LIGHT: This light shows if there in an electrical problem with the airbag system.
VEHICLE AHEAD INDICATOR:

This light displays green when a vehicle is detected ahead and will display amber when you are following a vehicle ahead much too closely.

First, start the engine, let it run for one second, then turn it off. After letting the engine sit for two or three seconds, repeat the process two more times.
What is the MIL? A dashboard light that comes on when the vehicle`s computer finds a problem that could cause excess pollution. Often this means you should repair your vehicle to avoid costly damage in the future. If the light is blinking or flashing, have your vehicle serviced at once.
Just be sure to have your car inspected as soon as possible after the light turns on. Don`t neglect needed engine repair! If nothing seems out of the ordinary, you can continue driving the car. The cause could be anything from a faulty oxygen sensor to a bad MAF sensor.
When all your dashboard lights turn on at once, it most commonly indicates an issue with the alternator or the charging system. It is common for all the dash lights to come on with no alternator output; low voltage can cause unusual electrical issues. The alternator should be tested at the time of battery replacement.
If you see orange or yellow dashboard lights it is reminding you that something needs to be serviced soon, like an oil change, or that something is wrong with your emissions system. While not an emergency, you should have a car mechanic look at the problem as soon as possible.
The check engine light — more formally known as the malfunction indicator lamp (MIL) — is a signal from the car`s engine computer that something is wrong. The light could be a minor issue, such as a faulty gas cap, or it could mean something more serious, such as a misfiring engine.
Red – indicates a potentially serious problem or safety issue and should be taken to your dealer as soon as possible. Yellow/Orange – something needs to be serviced or repaired soon. Green/Blue – indicates that your system is operating. You may see this color scheme when your headlights are on.
The emissions/exhaust system is the most likely culprit for many check engine lights being illuminated. There could be an exhaust leak or a problem with the catalytic converter. The mass airflow sensor (MAF) is another sensor that is easily tripped or can fail.
The warning light indicates a malfunction with one of the vehicle`s systems, but even minor problems can trigger an alert. If your check engine light is flashing, there is a serious issue, and you should turn off the engine as soon as it`s safe to get off the road.

Whining noise coming from engine.
ANSWER : Hi There,
I think you are on the right track in thinking of things like the alternator or the water pump as those are two things that immediately will correspond to RPM change when accelerating. If it is the alternator, try to notice if you voltage gauge fluctuates as this will indicate an alternator that is no longer maintaining a consistent charge and may be close to failing. You may also want to check for leaks around your water pump, particularly around the shaft area, as this is a common place for them to leak and will usually be the center point for the whining noise. This will also of course be accompanied by a change in engine temperature as well if there is coolant leaking. If you need any further help with this, please reach out to us here at YourMechanic as we are always hereto help.

I hear chirping from under the hood most prevalent while braking. The noise stops when the car is no longer moving.
ANSWER : Hello there. Thanks for the detailed description on your inquiry – it really helps us out. Based on what you have indicated, my first assumption would be that you have a loose serpentine / drive belt or a pulley that is showing early signs of wearing out. When the noise happens during breaking and normal operation, it tends to be caused by a belt that is frayed or loose. As you accelerate, the belt will tighten naturally; which is why the sound might slow down during idle. If the belt and pulley’s have not been replaced within 40,000 miles or so, it’s probably due to be completed. Since it’s possible that this could be from a different source, it’s also a good idea to have a professional mechanic complete a car is making a noise inspection to verify the source of this noise before making repairs.

Squeaking noise comes from wheels as it spins.
ANSWER : If the noise does not exist with the vehicle stopped (i.e., due to engine noise), then it is likely due to wheel bearings or the brakes. If brake related, unfortunately these sorts of noises can be related to the use of non-OEM rotors and brake pads and also the failure to re-apply factory specified shims and/or appropriate anti-squeal compounds and lubricants. You also want to check and ensure that no pistons are stuck in the calipers and the sliding pins in the torque plates are all freely moving. Unfortunately, once non-OEM parts and materials are used, and thus in essence an "experiment" is set up, brake noise can be a result. Missing shims should be considered and the possibility of a lubricant solution should be considered. If the pads are non-OEM and the noise arises from pad material, really the only solution is to remove the pads and install the more appropriate OEM Toyota friction material (rotors should be re-surfaced and/or de-glazed if any pad substitution is attempted). In the event that your car might have been retrofitted with something like high-performance carbon-metallic brake pads, note that those friction materials are well known to be more prone to unusual noises. If you would like a second opinion regarding this issue, please simply request a brake noise diagnostic and a certified mechanic will be dispatched by YourMechanic to evaluate your brakes, as well as the wheel bearings, and address all of your concerns.

High pitched whine noise is coming from behind or below glove box area. The noise occurs at low rpm at any speed, especially while turning left.
ANSWER : Hi there. The sound that you are hearing is probably from the blower motor to the heater / air conditioning evaporator. Remove the fuse to the blower motor and see if the sound stops. If the sound stops, then the motor or the squirrel cage is bent and rubbing. If the sound is still there when you remove the fuse, then it could be the alternator or power steering pump transmitting the sound through the cabin area. If you need further assistance with locating the source to the high pitch sound near your glove box, then seek out a professional, such as one from Your Mechanic, to help you.

My car makes a very odd beeping noise, what gives?
ANSWER : Hi there. This is most likely a service reminder indicator chiming. Take note of any messages on the display panel. It could also be the seat belt reminder chiming. This could be due to the belt being unfastened or the sensor thinking it is unfastened. A technician with a high end scanner, such as one from YourMechanic, can see which services are due and reset the reminders.
