The P1135 trouble code is a manufacturer-specific diagnostic trouble code (DTC) primarily associated with Toyota and Lexus vehicles. It signifies an issue with the Air/Fuel Ratio Sensor (Bank 1, Sensor 1) heater circuit. This sensor plays a crucial role in regulating the air-fuel mixture by providing the engine control module (ECM) with real-time data about
The P1326 trouble code is a diagnostic trouble code (DTC) that specifically relates to the Knock Sensor Detection System (KSDS) in certain Hyundai and Kia vehicles. When this code is triggered, it indicates that the engine control module (ECM) has detected an abnormal vibration signal from the knock sensor, which may suggest excessive wear on
The P0320 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the ignition/distributor engine speed input circuit. This code is triggered when the powertrain control module (PCM) detects a malfunction in the signals from the crankshaft position sensor (CKP) or camshaft position sensor (CMP). These sensors are crucial for determining the
The P0307 trouble code indicates that the Engine Control Module (ECM) has detected a misfire in cylinder number 7. This misfire can lead to incomplete combustion, resulting in poor engine performance, increased emissions, and potential engine damage if not addressed promptly. Understanding the causes, symptoms, and solutions for this code is essential for vehicle owners
The P305F trouble code is specific to certain Chevrolet vehicles, particularly those equipped with a dual battery system, such as the Chevy Malibu. This code indicates a performance issue with the Dual Battery Control Module (DBCM). The DBCM is responsible for managing the power distribution between the primary and auxiliary batteries, especially in vehicles that
The P0154 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the oxygen sensor circuit, specifically stating “O2 Sensor Circuit No Activity Detected (Bank 2, Sensor 1).” This code is logged when the Engine Control Module (ECM) detects that the signal from the oxygen sensor located in Bank 2, Sensor 1
The P0100 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the Mass Air Flow (MAF) sensor or its circuit. This sensor plays a crucial role in measuring the volume and density of air entering the engine, which is essential for the engine control module (ECM) to calculate the correct fuel-to-air
The P1133 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Heated Oxygen Sensor (HO2S) on Bank 1, Sensor 1. This sensor plays a crucial role in monitoring the air-fuel mixture in the engine exhaust, helping to ensure optimal performance and emissions control. When the engine control module (ECM) detects
The P2098 trouble code indicates a problem with the post-catalytic fuel trim system on Bank 2 of the engine, specifically that it is too lean. This means that the oxygen levels detected by the post-catalytic converter oxygen sensor are higher than expected, suggesting that there is an imbalance in the air-fuel mixture after combustion. The
The P2004 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Intake Manifold Runner Control (IMRC) system, specifically that the solenoid for Bank 1 is stuck in the open position. This code is generated by the vehicle’s Powertrain Control Module (PCM) when it detects that the IMRC actuator is not
The P0136 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the oxygen sensor circuit, specifically for Bank 1, Sensor 2. This code is part of the On-Board Diagnostics II (OBD-II) system, which monitors various components of the vehicle’s powertrain to ensure optimal performance and emissions control. When the Engine Control
