Definition and Symptoms

The P0443 code is a diagnostic trouble code (DTC) for the Ford Mustang. This code indicates an Evaporative Emission System (EVAP) malfunction, specifically a problem with the purge valve solenoid or canister purge valve. The EVAP system is responsible for collecting and storing fuel vapors from the fuel tank, and then releasing them into the engine to be burned. If this system malfunctions, it can cause an increase in emissions. Symptoms may include illuminated Check Engine Light, engine misfiring or hesitation during acceleration, and rough idling.

Causes of the P0443 Code

The most common cause of the P0443 code is a faulty EVAP purge valve solenoid or canister purge valve. These components are responsible for allowing air to enter and release fuel vapors from the fuel tank. If they become clogged or damaged, they will not be able to correctly regulate the flow of air and fuel vapors, resulting in an increase in emissions. Other causes may include clogged fuel cap or filler neck, vacuum hoses that have become disconnected or broken, electrical problems with the EVAP system components, and even physical damage to the EVAP components themselves.

Diagnostic Process

In order to diagnose a P0443 code on a Ford Mustang, a technician will first need to do a visual inspection of all related components such as vacuum hoses and connectors, wiring harnesses, relays and sensors. Once any obvious issues have been ruled out or repaired as necessary, a scan tool can be used to check for codes in other systems such as the mass airflow sensor (MAF), oxygen sensors (O2S), evaporative emission control (EVAP) system monitor (EVAPSM) and Fuel Tank Pressure Sensor (FTP). If any additional codes are present related to these systems, they must be diagnosed and repaired as necessary before proceeding with diagnosis of the P0443 code itself.
