P0716 – OBD-II Trouble Code Technical Description

Trouble code P0716 indicates a problem with the turbine speed sensor (torque converter) circuit signal.

What does the fault code mean P0716?

Trouble code P0716 indicates that the vehicle's computer has received an incorrect input signal from the transmission input shaft speed sensor (torque converter turbine) and is unable to determine the correct shift strategy. This may be caused by an error or malfunction of the sensor itself, its wiring, or other components involved in transmitting speed data.

Fault code P0716.

Possible reasons

Some of the possible causes of the P0716 trouble code are:

  1. Speed ​​sensor malfunction: The Crankshaft Position Sensor itself may be faulty or damaged, resulting in an incorrect or missing transmission input shaft (torque converter turbine) speed signal.
  2. Damaged or broken wiring: The wiring connecting the speed sensor to the vehicle's computer may be damaged, broken, or corroded, resulting in an incorrect signal or no signal at all.
  3. Problems with connections or connectors: Incorrect connections, corroded or oxidized speed sensor connectors can also cause P0716.
  4. Malfunctions of ignition system components: Problems with other ignition system components, such as ignition coils or sensors, can result in an incorrect transmission input shaft (torque converter turbine) speed signal.
  5. Car computer problems: Malfunctions or errors in the vehicle computer software that processes signals from the speed sensor can also cause the P0716 code.
  6. Engine problems: Some problems with the engine itself, such as a faulty power supply or cylinder misfiring, can cause the engine speed signal to be incorrect.

To accurately determine the cause of error P0716, it is recommended to conduct a comprehensive diagnosis of the vehicle using professional equipment and tools.

What are the symptoms of a fault code? P0716?

Symptoms for DTC P0716 may include:

  1. Unstable operation of the engine or its complete stop.
  2. Problems with shifting gears, such as jerking or delays when shifting gears.
  3. Increased engine speed when driving at high speed.
  4. The appearance of errors on the dashboard related to the operation of the transmission or engine.
  5. Loss of power when accelerating or going uphill.
  6. Sometimes you may hear strange noises from the transmission, such as grinding or knocking noises.
  7. Increased fuel consumption due to inefficient transmission operation.

These symptoms may occur to varying degrees depending on the specific cause of the P0716 code and the vehicle's design.

How to diagnose a fault code P0716?

When diagnosing DTC P0716, the following steps are recommended:

  1. Checking error codes: You should first use a diagnostic scanner to read the error codes and identify any other codes that may be related to problems with the transmission or engine system.
  2. Checking the speed sensor: It is necessary to check the condition of the speed sensor (turbine sensor) and its connections. This may include checking the sensor's resistance, its power supply and grounding, and checking for corrosion or damage to the wires and connectors.
  3. Wiring check: You should carefully inspect and check the wiring connecting the speed sensor to the vehicle computer. Pay attention to possible breaks, damage or corrosion on wires and connections.
  4. Checking engine operation: Check the engine for erratic rpms and vibrations or strange sounds that may indicate speed problems.
  5. Checking the car computer: In some cases, it may be necessary to check the operation of the vehicle's computer and its software for errors or malfunctions.
  6. Additional tests: Depending on your specific circumstances and the results of the previous steps, additional tests or inspections may be required to determine the cause of the P0716 code.

If you are unsure of your skills or experience in diagnosing automotive problems, it is recommended that you contact a professional auto mechanic or auto repair shop to perform diagnosis and repairs.

Diagnostic errors

When diagnosing DTC P0716, the following errors may occur:

  • Misinterpretation of symptoms: Some symptoms, such as jerking or loss of power, may be related to problems other than the speed sensor. Misinterpretation of symptoms can lead to misdiagnosis and replacement of unnecessary components.
  • Insufficient wiring check: Wiring and connections must be thoroughly checked to ensure there are no connection problems, breaks or corrosion. Insufficient wiring inspection can lead to undiagnosed electrical problems.
  • Car computer malfunctions: Malfunctions or errors in the vehicle's computer can also cause trouble code P0716. However, their diagnosis can be difficult and requires special equipment.
  • Problems with other transmission components: Some symptoms related to gear shifting or transmission performance can be caused not only by a faulty speed sensor, but also by other components of the transmission system, such as solenoids, valves, and even mechanical parts.
  • Insufficient expertise: Insufficient experience or knowledge of an auto mechanic can lead to incorrect diagnosis and repairs, which can increase repair time and cost.

To successfully diagnose and resolve the P0716 problem, you must have in-depth knowledge of automotive systems and use professional diagnostic equipment and tools.

How serious is the fault code? P0716?

Trouble code P0716 is serious because it indicates a problem with the automatic transmission input shaft speed sensor. A malfunction of this sensor can cause the transmission to not function properly, which can create dangerous driving conditions and cause serious damage to the vehicle. For example, changing gears incorrectly can cause sudden jerking or loss of control of the vehicle. Therefore, it is recommended that you contact a qualified technician immediately to diagnose and repair the problem when DTC P0716 appears.

What repair will help eliminate the code? P0716?

Troubleshooting DTC P0716 may require the following steps:

  1. Replacing the speed sensor: If the automatic transmission input shaft speed sensor is truly faulty, it should be replaced with a new or working one. This may solve the problem and resolve the P0716 code.
  2. Repair or replacement of wiring: If the cause of the error is damaged or broken wiring, it must be repaired or replaced. Connections must be checked for corrosion or oxidation.
  3. Diagnostics and repair of other components: The problem may be related not only to the speed sensor, but also to other components of the transmission. Therefore, additional diagnostics and repairs to solenoids, valves and other parts of the transmission may be required.
  4. Software update: Sometimes problems with error codes can be due to errors in the vehicle's computer software. In this case, a software update or reprogramming of the Engine Control Module (ECM) or Transmission Control Module (TCM) may be required.

Repairs should be performed by a qualified auto mechanic using the correct equipment and tools. After repairs are completed, it is recommended that you test drive and re-diagnosis to ensure that the problem has been successfully resolved and that DTC P0716 no longer appears.
