Code P0713 Infiniti Description
The P0713 Infiniti trouble code indicates that there is a high input signal coming from the transmission fluid temperature sensor. This sensor is responsible for monitoring the temperature of the transmission fluid, which is crucial for the proper operation of the transmission system. When the sensor detects a higher than normal temperature, it triggers this code to alert the driver or technician of a potential issue.
Common Causes of P0713 Infiniti
- Faulty Transmission Fluid Temperature Sensor: The sensor itself may be malfunctioning, providing incorrect temperature readings.
- Wiring Issues: A damaged or corroded wiring harness leading to the sensor can cause a high input signal.
- Transmission Control Module Malfunction: A problem with the TCM can also result in erroneous temperature readings.
- Transmission Fluid Level: Low transmission fluid levels or degraded fluid can lead to overheating and trigger this code.
- Overheating Conditions: Continuous heavy use or towing can cause the transmission fluid to overheat, triggering the sensor.
Symptoms of P0713 Infiniti
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
- Transmission Slipping: A high transmission fluid temperature can cause the transmission to slip or shift erratically.
- Harsh Shifting: The transmission may exhibit harsh or delayed shifting patterns due to improper fluid temperature readings.
- Overheating: The vehicle may experience overheating issues, especially during heavy use or in hot weather conditions.
- Decreased Fuel Efficiency: An overheating transmission can lead to decreased fuel efficiency as the system struggles to operate efficiently.
How to Fix P0713 Infiniti
- Diagnostic Testing: Use a scan tool to retrieve the trouble code and perform further diagnosis to pinpoint the exact cause of the high input signal.
- Check Sensor and Wiring: Inspect the transmission fluid temperature sensor and its wiring for any signs of damage or corrosion.
- Replace Sensor: If the sensor is faulty, replace it with a new one following manufacturer guidelines.
- Check Transmission Fluid: Verify the transmission fluid level and condition; top it off or perform a fluid flush if necessary.
- Clear Codes: Once the repair is complete, clear the trouble code from the vehicle's computer to reset the check engine light.
Cost to Fix P0713 Infiniti
The typical repair costs for addressing a P0713 Infiniti trouble code can vary depending on the exact cause of the issue. On average, the cost can range from $150 to $400, including parts and labor. However, it's important to note that specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. It's advisable to check with local shops for a more accurate estimate before proceeding with the repairs.

Frequently Asked Questions about P0713 Infiniti Code
1. What does the OBDII code P0713 mean on an Infiniti?
P0713 indicates that the Transmission Fluid Temperature (TFT) sensor is reporting an abnormally high voltage signal, suggesting the fluid temperature is excessively high or the sensor is malfunctioning.
2. What are the common symptoms of a P0713 code in an Infiniti?
Symptoms may include erratic or harsh shifting, transmission overheating, poor fuel economy, transmission going into limp mode, or the check engine light turning on.
3. What causes the P0713 code to appear in an Infiniti?
The code can be caused by a faulty TFT sensor, damaged or corroded wiring, poor electrical connections, low or degraded transmission fluid, or a failing transmission control module (TCM).
4. Can I still drive my Infiniti with a P0713 code?
It’s not recommended to drive for long periods when this code is active, as unresolved transmission temperature issues can lead to further damage and costly repairs.
5. How do I fix the P0713 code on my Infiniti?
Repairs may include replacing the TFT sensor, repairing damaged wiring or connectors, cleaning corroded terminals, or flushing and refilling the transmission fluid.
6. How do I diagnose a P0713 code on an Infiniti?
Start by scanning the vehicle with an OBDII scanner, inspecting the TFT sensor and its wiring for damage, checking transmission fluid levels and condition, and testing the sensor's resistance with a multimeter.
7. What is the Transmission Fluid Temperature (TFT) sensor's role in an Infiniti?
The TFT sensor monitors the transmission fluid temperature and sends this information to the transmission control module (TCM) to ensure optimal shifting and performance.
8. Can low transmission fluid cause a P0713 code?
Yes, low or degraded transmission fluid can cause the sensor to report incorrect readings, potentially triggering the P0713 code.
9. How much does it cost to fix a P0713 code on an Infiniti?
The repair cost depends on the issue but can range from $100 to $400 for parts and labor, with sensor replacement typically being the most common fix.
10. Will resetting the code clear the P0713 issue permanently?
Clearing the code with an OBDII scanner may temporarily turn off the check engine light, but the underlying issue must be addressed to prevent the code from returning.
