Experiencing a tire pressure warning light on your Nissan can be concerning, especially after recent tire service. If you’re seeing a C1704 error code, you’re likely dealing with a Tire Pressure Monitoring System (TPMS) issue. This article, crafted by the experts at obd-de.com, will delve into the C1704 Nissan code, helping you understand its potential causes and how to address it effectively.
Understanding the C1704 Code: TPMS Malfunction
The C1704 code on a Nissan vehicle indicates a malfunction within the TPMS. This system is designed to monitor the air pressure in your tires and alert you when it drops below a safe level. The C1704 code specifically points to a problem within the system’s communication or sensor readings, often occurring after tire rotations or replacements.
Potential Causes of C1704 After Tire Service
If you’ve recently had your tires serviced, particularly at a tire center, and now face the C1704 code, there are a few common scenarios:
-
TPMS Sensor Reset Not Performed: When tires are rotated or replaced, the TPMS sensors might need to be reset or recalibrated to your vehicle’s system. If the technician missed this step, it can trigger the C1704 code. Mechanics usually use a handheld TPMS tool to link with your Nissan’s system and perform this reset. Forgetting this step, especially if in a rush, is a common oversight.
-
Sensor Damage or Malfunction: While less frequent with simple tire service, there’s a slight chance a TPMS sensor could have been accidentally damaged during the tire work. Sensors can also malfunction over time due to battery depletion or wear and tear.
-
Incorrect Sensor Installation: In rare cases, if new sensors were installed, they might be incompatible with your Nissan or incorrectly installed, leading to communication errors and the C1704 code.

Troubleshooting and Solutions
Here’s how you can approach resolving the C1704 Nissan code:
-
TPMS Reset Procedure: Consult your Nissan owner’s manual for the specific TPMS reset procedure for your model. Sometimes a simple reset initiated through the dashboard controls can resolve communication glitches.
-
Check Tire Pressures: Ensure all tires are inflated to the recommended pressure listed on the sticker inside your driver’s side doorjamb. Correcting tire pressures can sometimes clear TPMS errors.
-
Professional TPMS Reset/Scan: Visit a trusted mechanic or tire service center. They can use a professional-grade TPMS scan tool to properly reset the system, read sensor data, and diagnose any sensor malfunctions.
-
Sensor Replacement (If Necessary): If a sensor is identified as faulty, replacement is usually straightforward. Ensure the replacement sensor is compatible with your Nissan model.
Addressing Other Nissan Codes (Like P0448)
While focused on C1704, you might encounter other codes concurrently. For Nissan Frontier owners, the P0448 code (Evaporative Emission Control System Vent Control Valve Circuit) is a known issue, often unrelated to tire service. Nissan has even issued Technical Service Bulletins addressing this P0448 code in Frontiers. If you see this alongside C1704, address them as separate issues.
Conclusion: Resolving Your Nissan TPMS Concerns
The C1704 Nissan code is typically related to TPMS issues, frequently arising after tire maintenance. By understanding the potential causes and following these troubleshooting steps, you can effectively address the problem and ensure your Nissan’s TPMS functions correctly. Remember, for accurate diagnosis and repair, especially if the reset doesn’t work, seeking professional assistance from a qualified mechanic is always recommended.
