Ford f150 hesitation and missing while driving is not only annoying, but it can also put you and other road users at risk.
Your F-150’s sluggish acceleration is a sign of a more serious problem that needs to be addressed immediately.
To blame for slow acceleration in a Ford F-150 are dirty air filters and mass airflow sensors (MAF), dirty fuel filters, malfunctioning fuel pumps, worn-out spark plugs (and) a clogged catalytic converter.
Transmission issues, bad ignition coils, dirty fuel injectors, clogged oil filters, and worn piston rings are less common, as are faulty TPS.
Ford F150 Hesitation And Missing While Driving: Causes & Fixes
A Clogged Air Filter
Ford F-150 engines might suffer if the air filter is clogged, as less air can reach the engine, suffocating it and decreasing its performance. Fuel usage will rise as a result. A severely blocked air filter may cause the engine to shut down.
You don’t need any particular training or tools to replace the filter on your F-150. As a result, the first thing you should do is do this check.
A Dirty Or Malfunctioning Mass Airflow Sensor (MAF)
If your Ford F-150’s mass airflow sensor (MAF) is defective or unclean, it can cause a loss of power, unpredictable idling, misfires, and noxious exhaust emissions like black smoke.
The mass airflow sensor is situated between the air filter box and the throttle valve in the engine’s intake system. It’s not just about getting the most out of your F-150’s power, but also about ensuring the lowest possible emissions.
What Happens If The MAF Sensor In A Ford F-150 Malfunctions?
A faulty or filthy MAF sensor won’t deliver accurate measurements to F-150’s control unit. Because it is no longer possible to compute the ideal amount of fuel to be injected into the combustion chambers, either too little or too much fuel is injected.
Too much or not enough fuel is being used by the engine. If the engine warning light in the instrument cluster comes on as a result of this, a diagnostic tool can detect the problem and provide an accurate diagnosis.
What Causes The F-150 MAF Sensor To Fail?
This sensor is prone to wear and tear. The engine control unit in your F-150 may receive increasingly erroneous values as the vehicle’s mileage grows.
A malfunctioning MAF sensor should be considered if the vehicle is experiencing a considerable reduction in performance and a high mileage.
This can happen early in the sensor’s life cycle, but it’s not unheard of. Water can get through the air filter while traveling at high speeds in heavy rain, causing the MAF sensor to malfunction significantly.
Occasionally, oil vapors from the crankcase ventilation can damage the MAF sensor after the engine has been turned off.
Do You Know How To Tell Whether The MAF Sensor In Your Ford F-150 Has Failed?
Reading the error codes with a diagnostic tool is fairly precise. The mass airflow sensor is malfunctioning if the OBD2 scanner displays the P0100 to P0104 codes.
However, there may be no error codes. If in doubt, the sensor may require replacement. After a thorough investigation, the MAF sensor should be replaced, but only if the effects of weak acceleration in your F-150 can be traced back to the sensor.
Is It Possible To Clear A Ford F-150 MAF Sensor That Has Become Clogged?
Restoring accurate readings to the mass airflow sensor might be aided by cleaning the sensor in some circumstances. Sensor parts are extremely delicate and should be handled with care.
Locate the MAF sensor in your F-150 and remove it from the housing by unplugging the electrical connectors.
At least 10 spurts of MAF cleaner should be sprayed onto the sensor and then allowed to air dry for at least an hour or until it has completely dried. To avoid damaging the sensor, never clean it with a cloth or cotton swabs.
There’s a chance that your vehicle doesn’t have a MAF sensor, especially if you’re dealing with an earlier model. Instead, the MAP sensor data is used by the control unit to calculate the mass flow rate of air. The symptoms of a faulty MAP sensor are quite similar to those of a faulty MAF sensor.
A Clogged Gas Filter
You can’t get enough fuel into your Ford F-150’s engine if the fuel filter is blocked. When you accelerate, the vehicle will jolt and lose power because of this. In the worst-case scenario, the engine fails to start because of a lack of fuel.
A lack of fuel might be detected by the F-150’s control unit, and the engine check light will come on. When you connect an OBD2 scanner to your vehicle, you may see an error number P0087, which indicates a problem with the fuel delivery system.
In A Ford F-150, What Causes A Clogged Fuel Filter?
To avoid costly engine damage, the gasoline filter in your vehicle is intended to trap rust particles and other trash from the fuel tank.
Inadequate fuel filter permeability and thus decreased engine fuel pressure can occur if you don’t keep up with the recommended maintenance schedule for your F-150 and don’t replace the filter on time.
The engine’s performance will suffer if the gasoline filter becomes too dirty, but it doesn’t matter much beyond that.
The Catalytic Converter Is Clogged
The Ford F-150’s exhaust system has a catalytic converter, which converts hazardous exhaust gases into more environmentally friendly byproducts.
Toxins build up and clog the catalytic converter over time, especially if the car has been driven a lot.
Ford F-150 Catalytic Converter Failure Symptoms: What Should You Look For?
Catalytic converter clogs in Ford F-150s can manifest in a variety of ways, including erratic engine performance, strange exhaust gas odors, poor fuel economy, illuminated engine check light, reduced performance over a certain speed, and even rattling noises.
Catalytic Converter Life Expectancy In A Ford F-150
Catalytic converters on Ford F-150 typically last 70,000 to 100,000 miles, depending on a variety of factors.
Catalytic converter failure can occur sooner if the engine misfires, the air-fuel mixture is incorrect, the oxygen sensor is malfunctioning, or the coolant in the combustion chambers is leaking.
The Oxygen Sensor Is Faulty
Oxygen sensors in the Ford F-150 continuously check the exhaust gases for pollutants and send the information to a control unit that adjusts the air-to-fuel ratio in the engine based on the data.
Oxygen sensors can malfunction, causing slow acceleration, loss of power, irregular idle, engine reluctance, or stalling if the control unit receives inaccurate information from them.
Can A Faulty O2 Sensor In A Ford F-150 Cause The Catalytic Converter To Fail?
Catalytic converter failures are most often the result of malfunctioning oxygen sensors. A skilled mechanic should be contacted right away if you detect an issue with the oxygen sensor (O2 sensor).
Catalytic converters, on the other hand, can easily cost over $1,000 to replace, making O2 sensors a bargain.
How Can I Tell If The Oxygen Sensor In My Ford F-150 Is Bad?
The F-150’s instrument panel’s engine check light will illuminate if the oxygen sensor malfunctions. Connecting an OBD2 scanner to your vehicle will allow you to figure out what’s wrong with it.
The upstream oxygen sensor is at fault if you encounter an error code between P0130 and P0135 or P0150 and P0155.
If your Ford F-150 isn’t accelerating properly, it could be for any number of reasons. You should always start with the most obvious causes, such as a problem with air intake or fuel delivery when investigating an issue.
Regardless, it’s a good idea for the general public to attend a session. The sluggish acceleration problem can be quickly diagnosed by a competent mechanic.
