P0716 - INPUT / TURBINE SPEED SENSOR A CIRCUIT RANGE / PERFORMANCE

POST UPDATED IN February, 2023

Description of DTC code P0716 Generic

When the DTC P0716 OBDII code is stored, it is because the PCM (Powertrain Control Module) has found a malfunction in the circuit that belongs to the ISS (Intake Speed Sensor), which is identified with the letter A. This designation is used on vehicles that are equipped with multiple Turbine Speed Sensors. Vehicles with multiple Turbine Speed Sensors use this designation.

This electromagnetic sensor usually has 3 wires and is used to control the input speed of the transmission. This is recognized by the PCM as the RPM (Revolutions Per Minute). It is located near the rear of the TCC (Torque Converter Clutch) and is screwed directly into the transmission case.

The turbine inlet speed is compared to the engine RPM speed, the amount of engine load, and the transmission output speed to determine the required inlet speed RPM. In case the actual turbine inlet speed does not match the required turbine inlet speed, the Check Engine lamp will turn on next to this code.

Symptoms of fault code P0716 Generic

  • Engine Malfunction Indicator Light (MIL) ON.
  • Constant changes in the speedometer.
  • Transmission shifts are erratic.
  • The transmission may not change at all.
  • Fuel efficiency is affected.
  • The engine may shut off when the vehicle stops.

Causes of OBD2 P0716 Generic

Reasons for setting the P0716 OBD2 fault code:

  • Wires and connectors may be loose or burned.
  • The Input Speed Sensor may be faulty.
  • The Output Speed Sensor may be damaged.
  • The transmission's Torque Converter Clutch may not be working properly.

Possible solutions of the DTC code P0716 Generic

Steps to troubleshoot the P0716 OBDII error code:

  • Check for Technical Service Bulletins (TSB).
  • Inspect the system wiring and connectors. If you find burn spots, corrosion, or any other feature that indicates poor condition, replace o repair these components. Also, check the battery cables.
  • Check the magnetic surfaces of the Input or Output Sensors for excessive metal debris. Remove such debris and reinstall the sensor.
  • Take into account the manufacturer's specifications, and test the sensors individually. If one of these sensors does not meet the specifications, you must replace them. It is necessary to replace both sensors, even though if only one is defective.
