Error code

OBD2 P0716

OBD2P0716
Diagnostic Trouble Code· Standard OBD-II fault code read from the vehicle's onboard diagnostics.

What it means

Input/Turbine Speed Sensor 'A' Circuit Range/Performance.

Severity

moderateCan drive, but harsh shifting and poor performance may occur.

Summary

P0716 indicates an issue with the Turbine Shaft Speed (TSS) sensor circuit range or performance in the transmission control module (TCM). This can affect how the TCM monitors and controls automatic transmission functions.

Symptoms

  • Check engine light on
  • Harsh shifting
  • Poor fuel economy

Common Causes

  • Faulty wiring between TSS sensor and TCM
  • Corroded or damaged connector at the TSS sensor
  • Weak internal transmission component leading to signal issues

Diagnosis

  1. Check TSS connector for corrosion or damage.
  2. Use a DVOM to test voltage at the TSS connector and compare with TCM readings.
  3. If no circuit issues are found, use an oscilloscope or specialized tester to check sensor signal during driving.

Fixes

  • Replace faulty wiring or damaged connectors
  • Replace the TSS sensor if it is defective

FAQ
