What Does Code P1751 Mean? DTC P1751 signifies that the Powertrain Control Module (PCM), or in some applications, the Transmission Control Module (TCM), has detected a performance anomaly within the circuit or mechanical operation of Shift Solenoid A. This code is often categorized as a “performance” fault rather than a definitive electrical circuit failure (which […]

What Does Code P1754 Mean? The diagnostic trouble code P1754 signifies a detected malfunction within the electrical circuit of the Coast Clutch Solenoid (CCS). In automatic transmissions, the Coast Clutch Solenoid is an electro-hydraulic control valve responsible for managing the hydraulic pressure directed to the coast clutch pack. The coast clutch is primarily engaged during […]

What Does Code P1755 Mean? DTC P1755 signifies a detected malfunction within the Intermediate Speed Sensor (ISS) circuit. This code is typically manufacturer-specific and points to an issue with the electrical signal emanating from the ISS, which is a critical component within the automatic transmission. The Powertrain Control Module (PCM) or Transmission Control Module (TCM) […]

What Does Code P1756 Mean? DTC P1756 indicates a performance issue with Shift Solenoid B within the automatic transmission. The Powertrain Control Module (PCM), also referred to as the Engine Control Module (ECM) or Transmission Control Module (TCM), monitors the operation of all shift solenoids to ensure proper gear engagement and hydraulic control. Shift Solenoid […]

What Does Code P1760 Mean? Diagnostic Trouble Code (DTC) P1760 indicates that the Powertrain Control Module (PCM) or Transmission Control Module (TCM) has detected an electrical short circuit within the control circuit for the Pressure Control Solenoid “A” (PCS ‘A’). This solenoid, often referred to as the Electronic Pressure Control (EPC) solenoid, is a critical […]

What Does Code P1761 Mean? DTC P1761 signifies a detected performance issue with Shift Solenoid C within the transmission. The Powertrain Control Module (PCM), or in some applications, the dedicated Transmission Control Module (TCM), monitors the hydraulic pressure and shifting behavior associated with Shift Solenoid C. This solenoid is a crucial component of the transmission’s […]

What Does Code P1762 Mean? DTC P1762 signifies an issue within the automatic transmission’s overdrive (OD) system, specifically indicating that the Powertrain Control Module (PCM), or integrated Transmission Control Module (TCM), has detected an anomaly suggesting the overdrive band has “failed off” or is not engaging properly. In modern automatic transmissions, overdrive typically refers to […]

What Does Code P1765 Mean? DTC P1765 indicates a detected electrical malfunction within the circuit of a specific timing solenoid, often referred to as a Variable Valve Timing (VVT) solenoid, Variable Camshaft Timing (VCT) actuator, or Oil Control Valve (OCV). This is typically a manufacturer-specific powertrain code. The Engine Control Module (ECM), also known as […]

What Does Code P1767 Mean? DTC P1767 signifies a detected malfunction within the Torque Converter Clutch (TCC) solenoid control circuit. This code indicates that the Powertrain Control Module (PCM) or Transmission Control Module (TCM) has identified an electrical anomaly that prevents it from effectively commanding the TCC solenoid. The TCC solenoid is an electro-hydraulic component […]

What Does Code P1768 Mean? DTC P1768 indicates an electrical malfunction within the circuit providing input for the driver-selectable transmission mode, specifically related to “Performance,” “Normal,” or “Winter” modes. In vehicles equipped with an automatic transmission and driver-selectable shifting characteristics, the Powertrain Control Module (PCM) or Transmission Control Module (TCM) receives a signal from a […]
