The P1351 trouble code is a manufacturer-specific diagnostic code that generally indicates an issue with the ignition control circuit or camshaft position sensor, depending on the vehicle make and model. This code can be triggered when the engine control module (ECM) detects a problem with the ignition system or camshaft timing while the engine is running. Understanding and resolving this code is crucial for maintaining

The P1273 trouble code is a manufacturer-specific diagnostic code primarily associated with Nissan vehicles. It indicates an issue with the air-fuel ratio (A/F) sensor 1 on bank 1 of the engine, specifically a lean shift in the fuel mixture. This code suggests that the engine control module (ECM) has detected a lean condition, meaning there’s too much air or not enough fuel in the combustion

The P1401 code is a diagnostic trouble code (DTC) related to the Exhaust Gas Recirculation (EGR) system, specifically indicating an issue with the Differential Pressure Feedback EGR (DPFE) sensor circuit. This code is commonly found in Ford vehicles, but can also appear in other makes equipped with similar EGR systems. When your vehicle’s onboard diagnostic system detects a problem with the DPFE sensor circuit, it

The P1494 trouble code is a diagnostic code related to the Evaporative Emission Control (EVAP) system in vehicles. Specifically, it indicates a problem with the Leak Detection Pump (LDP) switch or a mechanical fault in the system. This code is commonly found in Chrysler, Dodge, and Jeep vehicles, though it can appear in other makes as well. When this code is triggered, it means the

The P0422 diagnostic trouble code (DTC) is a generic OBD-II code that indicates a problem with the catalytic converter efficiency in Bank 1 of the engine. This code is typically triggered when the vehicle’s powertrain control module (PCM) detects that the catalytic converter is not operating at the expected efficiency level. Understanding and resolving this issue is crucial for maintaining your vehicle’s performance and ensuring

The P0326 trouble code is a diagnostic code related to the engine’s knock sensor system. When this code is triggered, it indicates that the powertrain control module (PCM) has detected an issue with the knock sensor circuit’s range or performance, specifically for bank 1 or a single sensor configuration. This code is crucial for maintaining optimal engine performance and preventing potential damage caused by engine

The P0110 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Intake Air Temperature (IAT) Sensor Circuit. This sensor plays a critical role in engine management by measuring the temperature of air entering the engine, which helps the Engine Control Module (ECM) or Powertrain Control Module (PCM) optimize the air-fuel mixture for efficient combustion. When the ECM detects a voltage

The P0894 diagnostic trouble code (DTC) is a generic powertrain code that indicates a transmission component slipping. When this code is triggered, it means the powertrain control module (PCM) has detected a discrepancy between the input and output speed sensor signals, suggesting that an internal transmission component is not functioning as intended. This code is applicable to many OBD-II vehicles manufactured from 1996 onwards, including

The P0223 trouble code is a diagnostic trouble code (DTC) that indicates a high input issue in the throttle/pedal position sensor or switch circuit “B.” This code is common in vehicles equipped with drive-by-wire (DBW) systems, where the throttle and accelerator pedal positions are electronically monitored and controlled. When this code is triggered, it often results in reduced engine performance or limp mode, signaling a

The P0513 diagnostic trouble code (DTC) is a generic powertrain code that indicates an issue with the vehicle’s immobilizer system. When this code is triggered, it means the Powertrain Control Module (PCM) has detected an incorrect or unrecognized immobilizer key. This code is crucial for vehicle security and can prevent the engine from starting if not resolved properly. P0513 Code Meaning P0513 Code Common Causes
