The P0562 trouble code is a diagnostic trouble code (DTC) indicating “System Voltage Low.” This code is triggered when the Powertrain Control Module (PCM) detects that the voltage in the vehicle’s electrical system has dropped below a predetermined threshold. A low voltage condition can lead to various performance issues, including difficulties starting the engine, malfunctioning
The P0137 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the oxygen sensor circuit, specifically signaling low voltage from the downstream oxygen sensor (Bank 1, Sensor 2). This sensor is crucial for monitoring the efficiency of the catalytic converter and ensuring optimal fuel-to-air ratios in the engine. When the powertrain
The P0134 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the oxygen sensor circuit, specifically stating “Oxygen Sensor Circuit No Activity Detected (Bank 1, Sensor 1).” This code is crucial for vehicle owners and DIY mechanics as it points to issues with the upstream oxygen sensor that monitors the air-fuel
The P0457 trouble code is a diagnostic trouble code (DTC) that indicates an issue within the Evaporative Emission Control (EVAP) system of a vehicle. Specifically, it signifies that the system has detected a large leak, often due to a loose, damaged, or missing fuel cap. The EVAP system plays a crucial role in preventing fuel
