What Does Code P1302 Mean? The diagnostic trouble code P1302, commonly identified as “Boost Calibration Low,” indicates that the Engine Control Module (ECM) or Powertrain Control Module (PCM) has detected a condition where the actual boost pressure within the forced induction system (turbocharger or supercharger) consistently falls below a predetermined, calibrated minimum threshold for a […]

What Does Code P1303 Mean? The OBD-II diagnostic trouble code P1303 signifies an EGR Calibration Fault. This indicates that the Powertrain Control Module (PCM) or Engine Control Module (ECM) has detected an inconsistency in the operational characteristics or expected flow rate of the Exhaust Gas Recirculation (EGR) system, rendering it outside its calibrated parameters. Unlike […]

What Does Code P1304 Mean? DTC P1304, defined as “EGR Calibration High,” signifies that the Engine Control Module (ECM), also known as the Powertrain Control Module (PCM), has detected an out-of-range condition within the Exhaust Gas Recirculation (EGR) system’s operational parameters. The EGR system is designed to reduce nitrogen oxide (NOx) emissions by recirculating a […]

What Does Code P1305 Mean? DTC P1305 indicates “EGR Calibration Low.” This signifies that the Engine Control Module (ECM), also commonly referred to as the Powertrain Control Module (PCM), has detected an inconsistency in the Exhaust Gas Recirculation (EGR) system’s performance. Specifically, the ECM monitors the actual flow or effective opening of the EGR valve […]

What Does Code P1306 Mean? DTC P1306 indicates a detected fault within the pull-in circuit of the automatic transmission’s kickdown relay. The powertrain control module (PCM), or in some architectures, the transmission control module (TCM), monitors the electrical characteristics of this circuit. The kickdown function is critical for rapid acceleration, allowing the transmission to downshift […]

What Does Code P1307 Mean? DTC P1307 signifies a detected fault within the “Kickdown Relay Hold Circuit.” This code indicates that the Powertrain Control Module (PCM), or Engine Control Module (ECM) in some architectures, has identified an electrical anomaly in the circuit responsible for controlling the automatic transmission’s kickdown relay. The kickdown function is critical […]

What Does Code P1308 Mean? DTC P1308 signifies an electrical fault within the Air Conditioning (A/C) compressor clutch control circuit. The Powertrain Control Module (PCM), often referred to as the Engine Control Module (ECM) or Engine Control Unit (ECU), is responsible for monitoring the operational integrity of various vehicle systems. In the context of P1308, […]

What Does Code P1309 Mean? DTC P1309 stands for Misfire Monitor AICE Chip Fault. This code is predominantly found in Ford vehicles and indicates that the Powertrain Control Module (PCM), also known as the Engine Control Module (ECM), has detected an internal fault within its misfire monitoring system. Specifically, it refers to an issue with […]

What Does Code P1313 Mean? The OBD-II diagnostic trouble code P1313, commonly defined as “Misfire Rate Catalyst Damage Fault – Bank 1,” indicates that the Engine Control Module (ECM) or Powertrain Control Module (PCM) has detected a critical level of misfires occurring specifically on Bank 1 of the engine. This level of misfiring is deemed […]

What Does Code P1314 Mean? DTC P1314 signifies a Misfire Rate Catalyst Damage Fault – Bank 2. This diagnostic trouble code is set by the Engine Control Module (ECM) or Powertrain Control Module (PCM) when it detects a misfire rate on engine Bank 2 that is sufficiently high to cause impending or actual damage to […]
