The P0055 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the heated oxygen sensor (HO2S) heater circuit for Bank 1, Sensor 3. This code is part of the OBD-II (On-Board Diagnostics II) system, which monitors various components of the vehicle’s engine and emissions systems. When the powertrain control module (PCM) detects an issue with the heater circuit of this specific
The P1305 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the igniter circuit, specifically related to cylinder number two in the ignition system. This code is primarily associated with vehicles manufactured by Toyota and Lexus, where it signifies that the Engine Control Module (ECM) is not receiving the Ignition Feedback (IGF) signal from the ignition coil of cylinder 2. Understanding
The P0783 code is a diagnostic trouble code (DTC) indicating a “3-4 Shift Malfunction” in a vehicle’s transmission system. This code is triggered when the powertrain control module (PCM) detects an issue with the transition between third and fourth gears, which can lead to performance problems and potential damage if not addressed promptly. Understanding this code is crucial for vehicle owners and DIY mechanics, as
The P0179 trouble code indicates a problem with the fuel composition sensor circuit, specifically a high input signal detected by the Engine Control Module (ECM). This code is crucial for vehicles equipped with flex-fuel systems, as it helps manage the fuel mixture based on the type of fuel being used. When the ECM detects a signal that exceeds the expected voltage range from the fuel
The P1164 trouble code is an OBD-II diagnostic code that indicates a problem with the Air/Fuel Ratio Sensor 1. This sensor plays a crucial role in monitoring the oxygen content in the exhaust gases and ensuring that the engine operates efficiently by maintaining the correct air-fuel mixture. When this code is triggered, it typically signifies that the sensor is experiencing a range or performance issue,
The P1764 trouble code is an OBD-II diagnostic code that indicates a malfunction within the vehicle’s transmission system, specifically related to the governor pressure sensor. This code can lead to various transmission performance issues, such as erratic shifting, failure to engage gears, and overall poor drivability. Understanding this code is crucial for vehicle owners and DIY mechanics who wish to diagnose and rectify the underlying
The P1170 trouble code is an OBD-II diagnostic code that indicates a problem with the engine’s oxygen sensor system, specifically related to the front heated O2 sensor. This code can lead to various performance issues in vehicles, including poor fuel economy, increased emissions, and potential engine damage if not addressed promptly. Understanding the P1170 code is crucial for vehicle owners and DIY mechanics who wish
The P2179 trouble code is a diagnostic trouble code (DTC) that indicates a “System Too Lean Off Idle Bank 2” condition in vehicles equipped with OBD-II systems. This code is triggered when the engine control module (ECM) detects that the air-fuel mixture in bank 2 of the engine is too lean (i.e., there is too much air compared to fuel) during off-idle conditions. A lean
The P1282 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the fuel pump relay control circuit. This code is generated when the Powertrain Control Module (PCM) detects an open or shorted condition in the fuel pump relay circuit while the ignition is on and the fuel pump relay is commanded to be active. Understanding this code is crucial for vehicle
The P2202 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the nitrogen oxide (NOx) sensor circuit on bank 1 of a vehicle’s engine. Specifically, it signifies that the NOx sensor is reporting a low voltage input to the engine control module (ECM). This can lead to increased emissions and reduced engine performance. Understanding the causes, symptoms, and solutions for this
