What Does Code P0716 Mean? DTC P0716 signifies that the Powertrain Control Module (PCM) or Engine Control Module (ECM) has detected an issue with the Input/Turbine Speed Sensor (ITSS or TSS) circuit’s range or performance. The Input/Turbine Speed Sensor is a critical component in automatic transmissions, responsible for monitoring the rotational speed of the transmission’s […]

What Does Code P0717 Mean? Diagnostic Trouble Code P0717 signifies that the Powertrain Control Module (PCM) or Transmission Control Module (TCM) has detected a loss of signal from the Input Shaft Speed (ISS) sensor, also often referred to as the Turbine Speed Sensor (TSS). This sensor is crucial for the proper operation of an automatic […]

What Does Code P0718 Mean? DTC P0718 signifies an detected by the Powertrain Control Module (PCM) or Transmission Control Module (TCM). The Input Speed Sensor (ISS), often referred to as the Turbine Speed Sensor (TSS) or Transmission Input Speed Sensor (TISS), is a critical component responsible for monitoring the rotational speed of the transmission’s input […]

What Does Code P0719 Mean? Diagnostic Trouble Code P0719 signifies a detected malfunction within the “B” circuit of the Torque Converter Clutch (TCC) / Brake Switch, specifically indicating a circuit voltage below the established operational threshold, often referred to as “Low Input.” The Engine Control Module (ECM) or Powertrain Control Module (PCM) continuously monitors various […]

What Does Code P0720 Mean? The diagnostic trouble code P0720, “Output Speed Sensor Circuit Malfunction,” indicates that the Powertrain Control Module (PCM) or Engine Control Module (ECM) has detected an electrical anomaly within the circuit of the transmission’s Output Speed Sensor (OSS). The OSS is a crucial component responsible for measuring the rotational speed of […]

What Does Code P0721 Mean? DTC P0721 signifies an issue with the Output Speed Sensor (OSS) Range/Performance. The Powertrain Control Module (PCM), or Transmission Control Module (TCM) in some applications, uses the OSS to monitor the rotational speed of the transmission’s output shaft, which directly correlates to vehicle road speed after the transmission. This sensor […]

What Does Code P0722 Mean? DTC P0722 signifies “Output Speed Sensor No Signal.” This code is set by the Powertrain Control Module (PCM) or Transmission Control Module (TCM) when it detects an absence of a rotational speed signal from the Output Speed Sensor (OSS) despite the transmission output shaft being expected to rotate. The OSS, […]

What Does Code P0723 Mean? DTC P0723 indicates an intermittent signal from the Output Speed Sensor (OSS) to the Powertrain Control Module (PCM) or Transmission Control Module (TCM). The OSS, often a magnetic reluctance or Hall-effect sensor, is crucial for monitoring the rotational speed of the transmission’s output shaft. This sensor generates a voltage signal […]

What Does Code P0724 Mean? DTC P0724 signifies that the Powertrain Control Module (PCM), or Engine Control Module (ECM) in some vehicles, has detected an abnormally high voltage condition in the circuit for the Torque Converter Clutch (TCC) / Brake Switch ‘B’. This code specifically points to an electrical anomaly where the PCM is receiving […]

What Does Code P0725 Mean? DTC P0725 signifies an “Engine Speed Input Circuit Malfunction.” This code is set by the Powertrain Control Module (PCM), also commonly referred to as the Engine Control Module (ECM) or Transmission Control Module (TCM) depending on vehicle architecture, when it detects an implausible, intermittent, or completely absent signal from the […]
