The Innova Car Scan Tool Screen 31703 can be a source of confusion for many car owners. Understanding what this code means and how to address it is crucial for maintaining your vehicle’s health. This article will provide a comprehensive guide to the Innova 31703 code, including its possible causes, diagnostic procedures, and solutions.
Understanding the Innova 31703 Code
The Innova 31703 code specifically relates to evaporative emission control system issues. More precisely, it typically indicates a problem with the Evaporative Purge Valve (EPV) or related components. This valve plays a critical role in preventing fuel vapors from escaping into the atmosphere. When the Innova scan tool displays 31703, it suggests a malfunction within this system, which can lead to increased emissions and potentially affect your vehicle’s performance.
What Causes the Innova Car Scan Tool Screen 31703?
Several factors can trigger the 31703 code on your Innova scan tool. A common culprit is a faulty or stuck-open EPV. This can be due to a mechanical failure within the valve itself or electrical issues affecting its operation. Other potential causes include a damaged or disconnected vacuum hose leading to the EPV, a malfunctioning vent control valve, or even a loose or damaged gas cap. Accurately diagnosing the root cause is essential before attempting any repairs.

Diagnosing the 31703 Code on Your Innova Scanner
Diagnosing the 31703 code requires a systematic approach. Begin by visually inspecting the EPV and its associated components. Look for any signs of damage, loose connections, or cracks in the vacuum hoses. Next, you can use your Innova scan tool to perform further tests, such as checking the EPV’s operation and monitoring the fuel vapor pressure. Using a multimeter to test the electrical connections to the EPV can also help pinpoint any electrical faults.
Fixing the Innova 31703 Issue
Once you’ve diagnosed the root cause, fixing the 31703 code can involve several different solutions. If the EPV is faulty, replacing it is often the most effective course of action. Damaged vacuum hoses should be replaced, and any loose connections should be tightened. If the vent control valve is malfunctioning, it too may need replacement. In some cases, simply tightening a loose gas cap can resolve the issue. Remember, addressing the underlying problem, not just clearing the code, is essential for long-term vehicle health.
Preventing Future 31703 Codes
Preventing future occurrences of the 31703 code involves regular maintenance and inspection of the evaporative emission control system components. Ensure your gas cap is always securely tightened after refueling. Regularly check the vacuum hoses for any signs of wear and tear, and consider replacing them proactively. Periodically inspecting the EPV and vent control valve for proper operation can also help prevent unexpected issues.
