Possible Causes of Ford F150 Check Engine Light Flashing on Acceleration

Ignition issues

A flawed ignition system can cause our Ford F150’s check engine light to flash during acceleration. Issues like worn-out spark plugs, defective ignition coil, a failing distributor, or problematic ignition wires can impede proper spark creation, resulting in engine misfires. This problem tends to intensify during acceleration, which could cause the check engine light to flash.

Transmission issues

Our check engine light could also flash due to transmission troubles. This could involve a stuck shift solenoid, low transmission fluid level, or a failing transmission control module. These issues, particularly if experienced during acceleration, can result in rough shifting, slips, or jerks that cause our vehicle’s check engine light to blink.

Fuel and air metering problems

Adequate air and fuel supply to the engine is essential for its optimal operation. If our Ford F150’s check engine light flashes during acceleration, the reason might be a clogged fuel injector, a compromised mass airflow sensor, a dysfunctional oxygen sensor, or a faulty throttle position sensor. This interference with the engine’s proper air-fuel mixture can cause performance issues and a flashing check engine light during acceleration.

Exhaust system abnormalities

Exhaust issues, including a failing catalytic converter or a damaged exhaust gas recirculation valve, could also be the culprits behind our flashing check engine light. These components help control our vehicle’s emissions. If they are compromised, it could lead to increased emission levels and trigger the check engine light.

Common Problems Specific to Ford F150

Spark plug or ignition coil faults

One common issue with Ford F150s is faulty spark plugs or ignition coils. For example, if spark plugs are worn out or the ignition coil is defective, the quality of the spark produced will be poor. This results in engine misfires, poor fuel economy, and the illuminating of our check engine light.

Exhaust gas recirculation (EGR) valve issues

The exhaust gas recirculation (EGR) valve in our Ford F150 recycles a portion of our exhaust gases back into the engine combustion process. This helps lower our vehicle’s emission levels. But if this valve malfunctions, it can lead to enhanced emission levels, reduced engine performance, and, consequently, a flashing check engine light.

Transmission shift solenoid malfunctions

Our Ford F150’s transmission shift solenoids control the fluid flow in our automatic transmission. If these solenoids fail, transmission fluid flow can be hindered, causing the vehicle to experience gearshift difficulties. If we feel a rough shift or the vehicle refusing to shift gears, it could signal solenoid issues catalysing the check engine light.

Using Onboard Diagnostics to Troubleshoot

Brief on the on-board diagnostic (OBD) system

The on-board diagnostic (OBD) system is a vital tool for diagnosing vehicle problems, including why our Ford F150 check engine light is flashing. This system stores codes that provide a snapshot of what could be wrong with our vehicle.

Reading and interpreting OBD codes

To read these OBD codes, we need an OBD2 scanner. We plug this device into our vehicle’s OBD2 port, usually situated beneath the dashboard. Once connected, the scanner will retrieve the codes. Interpreting these codes requires us to either refer to our vehicle’s manual or search for them online to understand their meanings.

Common OBD codes for Ford F150 and their meanings

For instance, some common OBD codes for a Ford F150 include P0300, signifying random/multiple cylinder misfire detected, and P0171, indicating the system is too lean. These codes direct us to areas we need to inspect further in our vehicle for possible issues.

Step-by-Step Guide to Inspecting Your Ford F150

Physical inspection process

While the OBD system helps us diagnose most issues, conducting a physical inspection can prove beneficial. This involves checking under the hood for leaks, inspecting our engine for any visible anomalies, checking the state of our spark plugs, and examining other vital components such as the air filter and fuel injectors.
