The P0330 trouble code indicates a malfunction in the Knock Sensor 2 Circuit for Bank 2 of the engine. This diagnostic trouble code (DTC) is part of the OBD-II system and is triggered when the Engine Control Module (ECM) detects an issue with the knock sensor’s operation, which is crucial for monitoring engine knocking and
The P015B trouble code is a diagnostic trouble code (DTC) that indicates an issue with the oxygen sensor in your vehicle. Specifically, it signifies a delayed response from the upstream oxygen sensor (Bank 1, Sensor 1) in the engine’s exhaust system. This sensor plays a critical role in monitoring the air-fuel mixture by measuring the
The P2187 trouble code is a diagnostic trouble code (DTC) that indicates the engine control module (ECM) has detected a lean air-fuel mixture at idle in bank 1 of the engine. This means that there is too much air and not enough fuel being delivered to the engine during idle conditions, which can lead to
The P0603 trouble code is a diagnostic error code that indicates a malfunction in the Powertrain Control Module (PCM), specifically related to its Keep Alive Memory (KAM). The KAM is crucial for storing important data about driving conditions, fuel efficiency, and engine performance, which the PCM uses to optimize vehicle operation. When the PCM fails
The P0125 trouble code is a common diagnostic error that indicates “Insufficient Coolant Temperature for Closed Loop Fuel Control.” This code is triggered when the Engine Control Module (ECM) does not detect the expected coolant temperature required for optimal engine operation within a specified timeframe after starting the vehicle. Essentially, it signals that the engine
The P1399 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the engine’s performance, specifically related to misfires or issues in the ignition system. This code is often manufacturer-specific, meaning its exact definition can vary between different car brands. However, it generally suggests that the vehicle’s onboard diagnostic system has detected
The P0405 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Exhaust Gas Recirculation (EGR) system, specifically relating to the EGR sensor circuit. When this code is triggered, it means that the Powertrain Control Module (PCM) has detected a low voltage signal from the EGR sensor, which is responsible for
The P0068 trouble code is a diagnostic fault code that indicates a discrepancy in the readings from the manifold absolute pressure (MAP) sensor, mass airflow (MAF) sensor, and throttle position sensor (TPS). This code typically arises when the Powertrain Control Module (PCM) detects that the signals from these sensors do not correlate correctly, which can
The P0193 trouble code is a diagnostic trouble code (DTC) that indicates a high input signal from the fuel rail pressure sensor. This sensor plays a critical role in monitoring the fuel pressure within the fuel rail, ensuring that the engine receives the appropriate amount of fuel for optimal performance. When the sensor detects a
The P0130 trouble code indicates an O2 Sensor Circuit Malfunction (Bank 1, Sensor 1). This code is a common diagnostic trouble code (DTC) that signals a problem with the oxygen sensor located upstream of the catalytic converter on the first bank of cylinders in your vehicle. The oxygen sensor plays a crucial role in monitoring
The P0421 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the efficiency of the warm-up catalytic converter, specifically stating that its efficiency is below the threshold during the warm-up phase of the engine. This code is triggered when the Powertrain Control Module (PCM) detects that the catalytic converter is not
