If you own a 2003 Ford Sport Track and are experiencing an evap code P0442, this guide will walk you through troubleshooting and fixing the issue using a smoke machine. When dealing with evap system issues, it’s important to have a thorough understanding of the system and its components.
In a separate video, the entire evap system is explained in detail, including how to find small evap leaks without a smoke machine. If you’re interested in learning more about the system itself, that video is a great resource.
For this specific troubleshooting method, a smoke machine from Ready Line, called “Ready Smoke,” is used. This machine, made in the USA, is designed to provide an efficient and reliable way to detect leaks within the evap system.
How the Smoke Machine Works
The Ready Smoke machine is lightweight, easy to operate, and comes with attachments for connecting to the vehicle’s battery. Once powered on, the machine produces smoke, which is then injected into the evap system to identify potential leaks.
The smoke is introduced at the service port and follows the entire pathway, including filling up the charcoal canister and the fuel tank. The process helps visualize any leaks that may be present in the system.
Troubleshooting the Canister Vent Valve
In the case of the 2003 Ford Sport Track, the canister vent valve assembly, a common failure point, is located above the spare tire. Accessing this valve requires removing the spare tire to expose the assembly for inspection and testing.
The vent valve is observed in its rest position to ensure it is functioning properly. Using a scanner or a back probe, the valve can be closed to stop smoke flow, allowing for a thorough assessment of its sealing capability.
Identifying and Fixing Leaks
During the video demonstration, a small leak is discovered at the connection to the charcoal canister. The use of the smoke machine proves instrumental in pinpointing the exact location of the leak. With the leak identified, the necessary repair can be carried out efficiently.
Conclusion
Utilizing a smoke machine for troubleshooting evap system issues offers a targeted and effective method for identifying leaks and faulty components. In the case of the 2003 Ford Sport Track, the use of the Ready Smoke machine facilitated the discovery of a small leak, leading to a cost-effective and timely repair for the customer. By following the steps outlined in the video, drivers can address evap codes like P0442 with confidence.

What is the video about?
The video is about using a smoke machine to detect a small evap leak in a 2003 Ford Sport track with an evap code p0 442.
What equipment is used in the video?
The video demonstrates the use of a Ready Line smoke machine to generate smoke and a scanner to monitor the vent valve function. Other tools include a Schrader valve removal tool, back probe, and power probe.
How is the smoke machine operated?
The smoke machine is connected to the battery using attachments, and upon powering it, the smoke is generated by pressing the red button. The smoke gradually builds up, becoming heavier as it runs.
What is the purpose of removing the Schrader valve?
The Schrader valve is removed to attach the smoke machine hose and inject smoke into the vehicle’s evap system to detect leaks.
How is the vent valve tested?
The vent valve is first observed in the rest position where smoke should come out. It is then closed using a scanner or by back probing the signal wire. The closure is verified by the absence of smoke, indicating a sealed vent system.
What is the outcome of using the smoke machine?
The small leak in the charcoal canister connection is detected, providing a cost-effective solution for the customer. The smoke machine accurately locates the leak, making it a valuable tool for diagnosis.
