P0713 – OBD-II DTC

OBD-II DTC P0713 – Transmission Fluid Temperature Sensor Circuit Low Input

DTC P0713 meaning

DTC P0713 refers to a diagnostic trouble code indicating a low input signal from the transmission fluid temperature sensor circuit. This sensor is crucial for monitoring the temperature of the transmission fluid, which helps the engine control unit (ECU) manage transmission performance and efficiency. A low input signal suggests that the sensor is not providing the expected voltage or resistance, which can lead to improper transmission operation.

DTC P0713 symptoms

Common symptoms associated with DTC P0713 may include:

• Transmission overheating
• Erratic shifting or harsh shifts
• Reduced fuel efficiency
• Check Engine Light illuminated
• Transmission slipping or failure to engage

DTC P0713 causes

Several factors can lead to the occurrence of DTC P0713, including:

• Faulty transmission fluid temperature sensor
• Wiring issues, such as shorts or open circuits
• Corroded or loose electrical connectors
• Faulty engine control unit (ECU)
• Low transmission fluid levels

DTC P0713 seriousness

DTC P0713 is considered a serious issue as it can affect the transmission’s performance and longevity. If left unaddressed, it may lead to further damage to the transmission system, resulting in costly repairs. Additionally, improper transmission operation can compromise vehicle safety and drivability.

How to diagnose DTC P0713

To diagnose DTC P0713, follow these steps:

1. Use an OBD-II scanner to confirm the presence of the P0713 code.
2. Inspect the transmission fluid level and condition.
3. Check the wiring and connectors related to the transmission fluid temperature sensor for damage or corrosion.
4. Test the resistance and voltage output of the transmission fluid temperature sensor.
5. Examine the ECU for any faults or updates.

How to fix DTC P0713 step-by-step instructions

To fix DTC P0713, follow these steps:

1. Ensure the transmission fluid is at the correct level and in good condition replace if necessary.
2. Repair or replace any damaged wiring or connectors associated with the transmission fluid temperature sensor.
3. Replace the faulty transmission fluid temperature sensor if testing indicates it is not functioning correctly.
4. Clear the DTC using an OBD-II scanner and take the vehicle for a test drive to ensure the issue is resolved.
5. Re-scan the vehicle to confirm that the P0713 code does not return.
