My car keep overheating. Does the muffler sensor have anything to do with that?
My car has a manual transmission.
Experienced mechanics share their insights in answering this question :
The muffler does not have a sensor but you do have a sensor for the catalyst on the engine called an O2 sensor. This sensor will not have anything to do with the engine overheating. You should have the engine cooling system checked for the overheating. You may have a cooling fan that is not coming on due to a fan switch in the radiator or the fan motor is bad. The most common cause of overheating is the fan switch or the thermostat stuck closed. Have the cooling system diagnosed as soon as possible may help to keep from damaging the engine by warpage on the cylinder head or blowing out a head gasket. Check to see if the cooling fan is coming on when you start to overheat and then check to see if cooling fans are getting power or not. The fan switch controls a fan relay and a thorough check of this system will be needed to isolate the failure. A certified technician from YourMechanic can come to your car’s location to inspect the overheating problem and ensure that the proper is made.

If you`re experiencing bad muffler symptoms, your vehicle is likely to misfire or overheat. A damaged muffler can cause blockages in your exhaust system, which result in abnormally high engine temperatures or a complete loss of power.
Overheating mufflers can be due to an engine problem as manifested in ignition timing. When the timing is horrible, some of the combustions occur in the exhaust system, making the muffler overheat. By all means, the muffler should demonstrate optimum performance, or else it can become defective.
Overheating can be caused by a: Cooling system leak – This is the most common cause for a car to overheat. The radiator, hoses, water pump, head gasket, and thermostat housing are all components of the cooling system, and all can be susceptible to leaks.
One common reason engines overheat while idling is a faulty or broken cooling system. This could include problems with the radiator, water pump, or fan belt.
Mufflers` Effect on Performance

An engine is able to generate more power, faster if it is able to get rid of all of the exhaust gases it produces quickly. By their nature, mufflers restrict exhaust flow or create back pressure, which slightly slows down your engine.

If ignored, any unresolved issues with your car`s muffler can significantly reduce the efficiency of your auto, cause severe engine problems, all resulting in very high auto repair bills.
The most common reasons a Honda Civic is overheating are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat.
The most common causes of overheating include low coolant level (including that due to leaks), a faulty thermostat, a plugged radiator, a faulty radiator pressure cap, collapsed hoses, non functioning cooling fans, and a faulty water pump or drive belt.
In some cases there may be air pockets in the heater core which can cause the heating of the inside of the vehicle to fluctuate between warm and cool air erratically. Engine overheating can be caused by a number of things such as low coolant levels, a faulty thermostat, or a failing coolant fan switch.
Car overheats when driving but not when idling

If your temperature gauge is fine until you make the car work, the most likely issue is coolant flow.

While mufflers do not change the amount of fuel your vehicle consumes, mufflers affect gas mileage because they can improve the vehicle`s fuel economy.
Although a DIY muffler delete is doable, it`s risky if you do not know what you`re doing. If your welding work is faulty, your car may suffer from damaging corrosion and exhaust leaks. So if you want to prevent this from happening, it`s best to pay a professional mechanic.
A cracked muffler could result in carbon monoxide leaking into the cabin of your vehicle. Breathing in these toxic exhaust fumes could cause passengers to become dizzy, nauseous, or even lose unconscious.
Loss of Engine Performance — If the pipes in the exhaust system become damaged or corroded, they can sometimes produce an exhaust leak that can cause the vehicle to experience performance issues, such as a decrease in power, acceleration, and fuel efficiency due to the loss of backpressure.
A broken exhaust can produce a hissing sound, rattling, a low rumble or even a loud roar. It might be louder when you accelerate the engine and quieter when idling. In some cases, it may sound like air being sucked out of the engine instead of an actual noise.
Typically, a car muffler will last 40,000 to 80,000 miles or around two to four years of average driving conditions.
In most U.S. vehicles, mufflers last approximately five to seven years. However, several factors such as frequent exposure to salt on roads, speed bumps, and potholes can result in premature aging. Regardless of the origin, muffler problems generally share common, easily identifiable characteristics.
If you`re noticing slow powertrain performance, reduced acceleration, a smell of rotten eggs or sulfur from the exhaust, dark exhaust smoke, or extreme heat from under the vehicle, these are symptoms of a clogged Catalytic Converter, and it should be replaced quickly.
Your car will still run with a broken or missing muffler, but it could be unsafe to drive. Depending on where you live, you run the risk of getting a ticket if you don`t get it replaced ASAP.
Carbon monoxide poisoning – Driving with a hole in your muffler can route exhaust fumes containing carbon monoxide back into your car`s interior. Even at low levels, carbon monoxide can cause serious health issues for both adults and children.
Leaks are the #1 reason a vehicle begins to overheat. Leaks in hoses, the radiator, water pump, thermostat housing, heater core, head gasket, freeze plugs and a few other things can all lead to problems with the vehicle`s cooling system.
Start your car`s engine and allow it to idle. Look through the radiator filler neck to see if the coolant flows. At this time, it should not be flowing as your car has not reached the operating temperature to cause the thermostat to open. If you find the coolant is flowing, it means the thermostat valve is open.
It gets even more concerning and confusing when car overheating suddenly returns to normal. This phenomenon can happen for many reasons, like a bad thermostat, a faulty radiator, or a coolant leak. As such, it`s best to get your car checked by a professional— like RepairSmith!
Temperature Sensor Failure

The temperature sensor`s role is to determine the engine`s temperature. If your temperature gauge reads hot but engine cool, it`s likely that you are getting a false measurement. This implies that the temperature sensor is failing or has malfunctioned.

My heat in my car stopped working two days ago and now my car is overheating. I put antifreeze in my car and it’s still overheating 2006 Pontiac Grand Prix
ANSWER : Hi there – you may have 2 related events here, a coolant leak, and a problem with the heater system. The current issue may be air inside the cooling system, which can cause overheating, and a lack of heater function. The lack of heater function could have 5 causes: the engine is not getting up to correct temperature (center of the gauge) due to a malfunctioning thermostat, the heater control valve is not letting hot coolant into the heater core, there is a restriction in the heater system that is preventing adequate hot coolant flow through the heater core, the heater fan is not working to transfer heat from the heater core to warm air for the passenger compartment, or the air blend doors inside the heater are not working properly to route warm air to the desired vents. I would recommend a heater system inspection](https://www.yourmechanic.com/services/heater-is-not-working-inspection) by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

Map sensor car won’t start up good ?
ANSWER : Your MAP sensor is an important input for your computer. It helps determine the load on the engine to calculate the correct amount of fuel to inject. It sometimes takes a few seconds for the vehicle to realize that the sensor is not producing a good signal.

At that point, it will use other methods to determine the fuel rate, such as pre-programmed fuel maps, throttle position, etc. I would suggest replacing the MAP sensor and retesting. If you would like to have it checked first, a certified technician from YourMechanic will be able to scan your vehicle and test components to determine the root cause of your starting issue before making a repair.

How long does a muffler last? How many miles it take to replace a muffler? Is theirs any difference between each muffler? (2 muffler)
ANSWER : There is a good chance it is the ’flex’ pipe section leaking. The life of the exhaust depends on mileage, driving conditions, and where you live. Snow and icy climates rip through exhaust systems with rust and road salt.

The 3.0 Hondas come with a stainless steel exhaust system which last for almost forever. The flex pipe typically cracks due to loose engine mounts. If someone has replaced the exhaust, then it may have rusted through. If you have the factory exhaust, then it should last the life of the car unless you live in a snow-type climate. If you want to have the noise looked at, a technician from YourMechanic can come to your home or office to inspect your exhaust system and let you know what adjustments should be done.

car is overheating and leaking water and anti freeze
ANSWER : Coolant leaks can occur because of cracked hoses, leaking gaskets, faulty water pumps, or damaged radiators. When the coolant level goes low, the engine will start to overheat due to the low coolant level. I would first recommend giving the cooling system a visual look over. If it is not obvious where the coolant leak is coming from, I would recommed having the cooling system pressure tested in order to determine the leak source. If you would like to have your cooling system pressure testedcoolant is leaking inspection, consider YourMechanic, as a certified technician can come to your home or office to inspect your cooling system.

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.

Suppose my car has temperature sensors, and if my car ignition is off, then it will allow me to connect my car to a mobile app
ANSWER : Hello, an app for accessing your car temp sensors (whether engine coolant or ambient air temp), will require access to the cars electronics through the OBD-II port, and a programmable communications device. The OBD-II port, and any temperature sensors on the vehicle are powered only while the ignition is in the Run/Start positions. To do what you are suggesting will require pretty much a stand-alone monitor and report piece of hardware, or a function driven by a wake-on-command facility using something like OnStar to retrieve temperature data.

I put the wrong key in my car and a few weeks later my car just shut down and it will not start I believe it’s the computer but…
ANSWER : Hi there. What had happened is the wrong key set the security to the vehicle. This is to prevent the vehicle from starting with the wrong keys. Try removing the battery cables (+) and (-) for 13 minutes. During that time, put the original key in the ignition and turn it on. Activate everything in the car even though there is no power. Then remove the key and hook up the battery cables. The computer should have reset and reset the security. If the security is still being tripped, then I recommend seeking out a professional, such as one from Your Mechanic, to help you
