5. What Are The Common OBD2 Error Codes And Their Meanings?

Understanding common OBD2 error codes is essential for diagnosing vehicle issues. Here’s a list of some of the most frequent codes and their meanings:

5.1. P0101 – Mass Air Flow (MAF) Sensor Circuit Range/Performance

This code indicates an issue with the mass air flow (MAF) sensor, which measures the amount of air entering the engine. A faulty MAF sensor can cause poor engine performance, reduced fuel economy, and stalling. According to a 2023 study by AAA, MAF sensor issues are responsible for approximately 5% of “Check Engine” light incidents.

5.2. P0171 – System Too Lean (Bank 1)

This code indicates that the engine is running lean, meaning there is too much air and not enough fuel in the air-fuel mixture. This can be caused by a vacuum leak, a faulty oxygen sensor, or a clogged fuel injector.

5.3. P0300 – Random/Multiple Cylinder Misfire Detected

This code indicates that the engine is misfiring, meaning one or more cylinders are not firing properly. This can be caused by faulty spark plugs, ignition coils, or fuel injectors. A misfiring engine can cause rough idling, reduced power, and increased emissions.

5.4. P0420 – Catalyst System Efficiency Below Threshold (Bank 1)

This code indicates that the catalytic converter is not functioning efficiently. The catalytic converter reduces harmful emissions from the exhaust system. A faulty catalytic converter can cause increased emissions, reduced fuel economy, and a failed emissions test.

5.5. P0442 – Evaporative Emission Control System Leak Detected (Small Leak)

This code indicates a small leak in the evaporative emission control system (EVAP). The EVAP system prevents fuel vapors from escaping into the atmosphere. A leak in the EVAP system can cause increased emissions and a failed emissions test.

5.6. P0505 – Idle Air Control (IAC) System Malfunction

This code indicates a problem with the idle air control (IAC) system, which regulates the engine’s idle speed. A faulty IAC system can cause rough idling, stalling, and difficulty starting the engine.

5.7. P0700 – Transmission Control System Malfunction

This code indicates a problem with the transmission control system. This can be caused by faulty sensors, solenoids, or a malfunctioning transmission control module (TCM). Transmission issues can lead to shifting problems, reduced performance, and potential damage to the transmission.

5.8. P0113 – Intake Air Temperature Sensor Circuit High Input

This code indicates a high voltage reading from the intake air temperature (IAT) sensor, which measures the temperature of the air entering the engine. A faulty IAT sensor can cause incorrect fuel calculations, leading to poor engine performance and reduced fuel economy.

5.9. P0135 – O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)

This code indicates a problem with the heater circuit of the oxygen sensor. The heater circuit helps the oxygen sensor reach its operating temperature quickly. A faulty heater circuit can cause delayed sensor response and inaccurate readings.

5.10. P0301 – Cylinder 1 Misfire Detected

This code indicates a misfire in cylinder 1. This can be caused by a faulty spark plug, ignition coil, fuel injector, or other engine issues.

Understanding these common OBD2 error codes can help you diagnose and address vehicle issues more effectively. Visit OBD2-SCANNER.EDU.VN for more comprehensive code definitions and troubleshooting guides.
