P1716 – OBD-II DTC

OBD-II DTC P1716 – TFT Sensor Out Of Self Test Range

DTC P1716 meaning

DTC P1716 refers to a diagnostic trouble code indicating that the Transmission Fluid Temperature (TFT) sensor is out of its self-test range. This code is specific to the transmission system and is triggered when the Engine Control Module (ECM) detects that the TFT sensor’s readings are not within the expected parameters during a self-test. The TFT sensor plays a crucial role in monitoring the temperature of the transmission fluid, which is essential for optimal transmission performance and longevity.

DTC P1716 symptoms

Common symptoms associated with DTC P1716 may include:

• Illuminated check engine light
• Transmission overheating
• Erratic shifting or harsh transmission behavior
• Decreased fuel efficiency
• Transmission slipping or failure to engage

DTC P1716 causes

Several factors can lead to the triggering of DTC P1716, including:

• Faulty Transmission Fluid Temperature sensor
• Wiring issues, such as damaged or corroded connectors
• Short circuits or open circuits in the sensor circuit
• Faulty Engine Control Module (ECM)
• Contaminated or low transmission fluid

DTC P1716 seriousness

DTC P1716 can be considered serious as it may indicate potential issues with the transmission system. If left unaddressed, it can lead to:

• Increased wear and tear on transmission components
• Complete transmission failure
• Unsafe driving conditions due to erratic shifting

It is advisable to diagnose and repair the issue promptly to avoid further damage and ensure safe vehicle operation.

How to diagnose DTC P1716

To diagnose DTC P1716, follow these steps:

1. Use an OBD-II scanner to confirm the presence of the P1716 code.
2. Check for any additional trouble codes that may provide more context.
3. Inspect the Transmission Fluid Temperature sensor and its wiring for damage or corrosion.
4. Test the TFT sensor’s resistance and voltage output according to manufacturer specifications.
5. Examine the transmission fluid level and condition.
6. Clear the codes and perform a road test to see if the code reappears.

How to fix DTC P1716 step-by-step instructions

To fix DTC P1716, follow these steps:

1. Identify and replace a faulty Transmission Fluid Temperature sensor if necessary.
2. Repair or replace any damaged wiring or connectors associated with the TFT sensor.
3. Ensure the transmission fluid is at the correct level and in good condition replace if contaminated.
4. Recheck the sensor’s output after repairs to ensure it is within the specified range.
5. Clear the DTC using an OBD-II scanner.
6. Perform a road test to confirm that the issue has been resolved and the code does not reappear.
