What Does Code P1582 Mean? The diagnostic trouble code P1582, often specific to Ford vehicles but appearing in others, signifies “Electronic Throttle Monitor Data Available.” Unlike most OBD-II codes that indicate a malfunction, P1582 is typically an informational code. It means that the Powertrain Control Module (PCM), also referred to as the Engine Control Module […]

What Does Code P1583 Mean? DTC P1583, commonly defined as Electronic Throttle Monitor Cruise Disable, indicates that the Powertrain Control Module (PCM) or Engine Control Module (ECM) has detected a critical anomaly within the Electronic Throttle Body (ETB) monitoring system. This code is often specific to Ford vehicles and points to an inconsistency or fault […]

What Does Code P1584 Mean? DTC P1584 signifies a malfunction detected by the Transmission Control Unit (TCU) within the Idle Position Error (IPE) circuit. The IPE circuit, often directly related to or deriving its signal from the Throttle Position Sensor (TPS) or a dedicated Idle Position Switch, provides crucial data to the TCU regarding the […]

What Does Code P1585 Mean? DTC P1585 indicates a detected malfunction within the vehicle’s Throttle Control Unit, often specifically referring to issues with the Electronic Throttle Body (ETB) assembly itself, or its immediate control circuit. In modern drive-by-wire systems, the Engine Control Module (ECM) or Powertrain Control Module (PCM) directly commands the throttle plate position […]

What Does Code P1586 Mean? The diagnostic trouble code P1586 signifies that the Powertrain Control Module (PCM), also referred to as the Engine Control Module (ECM) in many applications, has detected an inconsistency or malfunction within the electronic throttle control (ETC) system, specifically regarding the throttle plate position. In drive-by-wire (DBW) systems, the PCM commands […]

What Does Code P1587 Mean? The OBD-II diagnostic trouble code P1587 signifies a Throttle Control Unit Modulated Command Malfunction. This code is specifically related to the electronic throttle control (ETC) system, often referred to as “drive-by-wire.” In this system, the Engine Control Module (ECM) or Powertrain Control Module (PCM) does not directly manipulate the throttle […]

What Does Code P1588 Mean? DTC P1588 signifies that the Powertrain Control Module (PCM), or Engine Control Module (ECM) in some applications, has detected a critical malfunction within the Electronic Throttle Body (ETB) assembly, specifically indicating a loss of function or integrity of its mechanical return spring. In a Drive-by-Wire (DBW) system, the throttle plate […]

What Does Code P1589 Mean? DTC P1589 indicates that the Transmission Control Unit (TCU) is unable to achieve or maintain the desired throttle angle as communicated to the Engine Control Module (ECM/PCM). This code specifically flags a discrepancy between the throttle angle requested by the TCU (which dictates engine torque for smooth gear shifts, traction […]

What Does Code P1600 Mean? The OBD-II diagnostic trouble code P1600 signifies a “Loss of Keep Alive Memory (KAM) Power; Open Circuit.” This code is set by the Powertrain Control Module (PCM), also commonly referred to as the Engine Control Module (ECM) or Engine Control Unit (ECU), when it detects an interruption or absence of […]

What Does Code P1601 Mean? Diagnostic Trouble Code (DTC) P1601 indicates a serial communication error between the Engine Control Module (ECM), often referred to as the Powertrain Control Module (PCM), and the Transmission Control Module (TCM). This code is set when the ECM/PCM fails to receive expected data or receives corrupted/implausible data from the TCM […]
