When the engine of your Honda Accord begins to struggle, it can be frustrating. One of the most common issues is a sudden loss of power while driving, which can be caused by a variety of things.
It’s never a pleasant experience, but rest assured that you’re not alone. Loss of power is a common problem among Honda Accord owners. It usually signifies a problem with the vehicle’s fuel-delivery system or possibly the spark plugs. However, you can do a few things to identify the root cause of the issue.Â
In this blog post, we will discuss five common causes of your Honda Accord losing power while driving and how to address them.
Common Causes Of A Honda Accord That Loses Power While Driving
Many things can cause your Honda Accord to lose power while driving. Here are five of the most common.
Low Fuel Pressure
One possible cause of your Honda Accord suddenly losing power while driving is low fuel pressure. Low fuel pressure affects how gasoline gets from the tank to the engine, which can then cause your car to lose power or even stall completely.
This can be caused by several things, including clogged fuel filters, failing fuel pumps, or old fuel injectors. A hole in the fuel line can also cause the same issue.
Faulty Ignition System
Another possible cause for your Honda Accord suddenly losing power is a faulty ignition system. The ignition system is responsible for producing the spark for combustion to occur and for the engine to function correctly.
If the spark plugs aren’t firing properly or the distributor cap is damaged, your engine won’t get the spark it needs to run properly, and you will experience a loss of power. This will cause your car to lose power or stall completely.
Faulty Mass Air Flow Sensor
The mass air flow sensor (MAF) measures how much air enters your Honda’s engine so that it can adjust the air-fuel ratio accordingly for optimum performance.
If this sensor fails or malfunctions, then it can cause your vehicle to lose power while accelerating. In addition, poor gas mileage and increased emissions output may also indicate a faulty MAF.
Malfunctioning Throttle Position Sensor
The throttle position sensor (TPS) monitors how far open/closed your throttle body is so that it can adjust fueling levels accordingly for optimal performance and efficiency.
If this sensor fails, it can cause a sudden loss of power while driving due to incorrect fueling levels being sent to the engine computer, resulting in poor performance and reduced overall efficiency.
Faulty EGR Valve
The exhaust gas recirculation valve controls emissions levels by recirculating exhaust gases back into the intake manifold so they can be burned again to reduce emissions output.
When this valve goes bad, it can cause your car to lose power due to an incorrect mixture of air and fuel being sent into the cylinders resulting in incomplete combustion happening within them.
Honda Accord Power Loss Fixes
If your Honda Accord is suddenly losing power while driving, then the first step is to identify the root cause of the issue. Once you have done this, you can start to address the problem.
Check The Fuel System
The first thing you want to check is your fuel system. Ensure the fuel filter isn’t clogged and the fuel pump is in good working condition. Also, check for any leaks in the fuel lines and replace them if needed.
You should replace the fuel filter in your Honda Accord every 30,000 to 50,000 miles. The fuel pump should also be inspected and replaced if necessary.
Check The Ignition System
The next step is to check the ignition system. Check the spark plugs, distributor cap, and rotor for any signs of wear or damage. If they are damaged, then You should replace them.
Sometimes the spark plugs need to be gapped correctly for them to work properly. If the gap is too wide or too narrow, it can cause your engine to misfire and lose power. You should also clean dirty spark plugs of deposits to ensure they are working correctly.
Check The Mass Air Flow Sensor
If the fuel and ignition systems are in good working order, you should check the mass air flow sensor. You can locate the MAF between the throttle body and the air filter box.
The MAF should be cleaned or replaced if needed. Clean it with an electrical contact cleaner to remove any dirt or debris that may have built up over time. If cleaning the MAF does not solve the problem, it may need to be replaced.
Check The Throttle Position Sensor
You should also check the throttle position sensor if your Honda Accord is losing power while driving. This sensor can be found on the side of the throttle body.
Clean the TPS if it is dirty and inspect it for any signs of wear or damage. If the sensor is not working correctly, then it should be replaced.
Check The EGR Valve
Finally, check the exhaust gas recirculation (EGR) valve to see if it is functioning correctly. This valve is located at the rear of the engine, on the intake manifold.
Clean the EGR valve with carburetor cleaner and inspect it for any signs of wear or damage. If necessary, replace the EGR valve to fix the issue.
FAQ
Why Is My Honda Accord Not Accelerating Properly?
If your Honda Accord is not accelerating properly, several possible causes exist. Common issues include a lack of fuel or spark, clogged air filters, an issue with the timing belt, or a faulty oxygen sensor. A lack of power while driving can also be caused by a problem with transmission fluid, the engine’s computer system, or an issue with the brake booster.
How Do I Get My Honda Accord Out Of Limp Mode?
Limp mode occurs when the car’s computer detects a problem with its emission system or malfunction somewhere in the transmission. To get your Accord out of limp mode, you must reset the ECU – the car’s computer – by disconnecting the battery or using a scan tool.
Doing this will allow your car to operate normally again. Still, you must get it inspected by a certified mechanic immediately to identify and resolve the underlying issue.
