engine and transmission. They are split into several categories and can cover fuel, injection, ignition and emission control problems. Below is a list of some of the most common \"P\" codes and their descriptions. OBD-II codes related to fuel injection and air-fuel mixture P0171 - System too lean (Bank 1): Indicates that the air-fuel mixture is too lean in Bank 1, which may be caused by a vacuum leak or a faulty oxygen sensor. P0172 - System Too Rich (Bank 1): The air-fuel mixture is too rich in Bank 1. This can be caused by a faulty MAF sensor, faulty fuel injectors or a faulty fuel pressure regulator. P0174 - System too lean (Bank 2): Similar to P0171, but applies to Engine Bank 2. P0175 - System Too Rich (Bank 2): Indicates that the engine is receiving too much fuel in Bank 2. P0190 - Fuel Pressure Sensor Faulty Circuit: Problems in the fuel pressure sensor circuit that could cause an incorrect fuel pressure reading. OBD-II codes related to the ignition system P0300 - Multiple Misfires: The engine has experienced multiple misfires and the error is not cylinder specific. P0301 - P0312 - Cylinder 1-12 misfire: These codes indicate a specific ignition problem in each cylinder. For example, P0301 indicates a problem with cylinder 1 and P0312 indicates a problem with cylinder 12. P0320 - Crankshaft position sensor circuit failure: This code indicates a problem with the crankshaft position sensor, which is responsible for synchronising ignition and fuel injection. P0350 - P0358 - Primary\/Secondary Ignition Coil Circuit: Problems in the ignition coil control circuit affecting the operation of the corresponding cylinder. OBD-II codes related to the emissions system P0420 - Catalyst Efficiency Below Threshold (Bank 1): This code indicates that the efficiency of the catalytic converter in Bank 1 is lower than expected, suggesting that the converter is not functioning properly. P0430 - Catalyst Efficiency Below Threshold (Bank 2): Similar to P0420, but for Engine Bank 2. P0440 - Evaporative Leak Control System: This code indicates a problem in the Evaporative Emissions Control System (EVAP), which is responsible for capturing fuel vapour from the fuel tank and sending it to the engine. P0455 - Large EVAP Leak: Detecting a large leak in the evaporative emissions system. Transmission-related OBD-II codes P0700 - General malfunction in transmission: This is a general code indicating a problem with the automatic transmission, without giving specific details. P0715 - Input Speed Sensor Circuit: A problem in the transmission input speed sensor circuit, which may affect shift performance. P0730 - Incorrect Gear Ratio: This code indicates that the transmission gear ratio is not correct, suggesting a mechanical malfunction or faulty sensor. OBD-II codes related to engine control P0600 - Fault in the serial communication network: This indicates a problem in the communication network between ECUs. P0606 - ECU processor fault: The engine ECU has detected an internal problem and needs to be checked or replaced. P0620 - Generator\/Alternator circuit fault: Problems in the alternator control circuit, which may lead to battery charging problems. P0650 - Check Engine Indicator Light Circuit Fault: This code indicates that the Check Engine light is not working properly or not illuminating when required. How to use these codes for diagnostics? OBD-II codes are extremely useful for diagnosing vehicle problems. However, a single fault code does not always provide all the information needed to fully repair your vehicle. Once you identify a code, it is important to check for possible causes, physically inspect the components involved, and perform the necessary tests to confirm the diagnosis. Frequently asked questions about OBD-II codes How do I read OBD-II codes? You need an OBD-II scanner that plugs into your vehicle's diagnostic port. Once connected, the scanner will display the codes stored in the ECU. What do I do if I get a fault code? Depending on the severity of the code, you can either try a reset to see if the problem is temporary, or consult a mechanic for further diagnosis. Do all vehicles have the same OBD-II codes? Yes, OBD-II fault codes are standardised for all OBD-II compatible vehicles. However, there may also be manufacturer-specific codes.
