6.1. P0300: Random/Multiple Cylinder Misfire Detected

This code indicates that the engine is experiencing misfires in multiple cylinders or that the misfire is random. It could be caused by faulty spark plugs, ignition coils, fuel injectors, or vacuum leaks. According to a study by AAA, misfires can reduce fuel efficiency by up to 30%.

6.2. P0171: System Too Lean (Bank 1)

This code indicates that the air-fuel mixture in Bank 1 of the engine is too lean, meaning there is too much air and not enough fuel. It could be caused by a vacuum leak, a faulty oxygen sensor, or a clogged fuel filter.

6.3. P0420: Catalyst System Efficiency Below Threshold (Bank 1)

This code indicates that the catalytic converter in Bank 1 of the engine is not functioning efficiently. It could be caused by a faulty catalytic converter, a damaged oxygen sensor, or exhaust leaks.

6.4. P0113: Intake Air Temperature Sensor Circuit High Input

This code indicates that the intake air temperature (IAT) sensor is sending a high voltage signal to the engine control unit (ECU). It could be caused by a faulty IAT sensor, a wiring problem, or a problem with the ECU.

6.5. P0301: Cylinder 1 Misfire Detected

This code indicates that the engine is experiencing a misfire in cylinder 1. It could be caused by a faulty spark plug, ignition coil, fuel injector, or vacuum leak in cylinder 1.

6.6. P0401: Insufficient EGR Flow

This code indicates that there is insufficient flow in the Exhaust Gas Recirculation (EGR) system. The EGR system is responsible for recirculating a portion of the exhaust gas back into the engine to reduce NOx emissions. This code may be caused by a clogged EGR valve, a faulty EGR sensor, or a vacuum leak in the EGR system.

6.7. P0011: A Camshaft Position – Timing Over-Advanced or System Performance (Bank 1)

This code indicates an issue with the camshaft position in Bank 1 being over-advanced. It suggests the camshaft timing is more advanced than what the engine control unit (ECU) is commanding. Potential causes include a faulty camshaft position actuator, low oil level, or a timing chain issue.

6.8. P0102: Mass or Volume Air Flow Circuit Low Input

This code indicates that the Mass Air Flow (MAF) sensor is sending a low voltage signal to the ECU. The MAF sensor measures the amount of air entering the engine. This code may be caused by a dirty or faulty MAF sensor, a wiring problem, or a vacuum leak.

6.9. P0131: O2 Sensor Circuit Low Voltage (Bank 1, Sensor 1)

This code means the oxygen sensor in Bank 1, Sensor 1, is reporting a low voltage. This sensor is crucial for monitoring the oxygen levels in the exhaust gases. Causes could include a faulty oxygen sensor, wiring issues, or exhaust leaks near the sensor.

6.10. P0507: Idle Control System RPM Higher Than Expected

This code indicates that the engine’s idle speed is higher than the manufacturer’s specified RPM. This can be caused by a faulty idle air control valve, vacuum leaks, or throttle body issues.
