When your vehicle detects a problem, it stores a DTC in the OBD2 system. The DTC is a five-character code that provides information about the nature and location of the issue.

• P0171 – System Too Lean (Bank 1): Indicates that the engine is receiving too much air or not enough fuel.
• P0300 – Random/Multiple Cylinder Misfire Detected: Suggests that one or more cylinders are not firing correctly.
• P0420 – Catalyst System Efficiency Below Threshold (Bank 1): Indicates a problem with the catalytic converter.
• P0101 – Mass Air Flow (MAF) Sensor Circuit Range/Performance: Suggests an issue with the MAF sensor.
• P0113 – Intake Air Temperature Sensor Circuit High Input: Indicates a problem with the intake air temperature sensor.

5.2 Identifying Misfires

Misfires can cause rough idling, reduced power, and increased emissions. Use the OBD2 app to monitor the misfire counters for each cylinder. If a cylinder shows a high misfire count, it may indicate a problem with the spark plug, ignition coil, or fuel injector.

5.3 Monitoring Fuel Trim

Fuel trim values indicate how the engine control unit (ECU) is adjusting the fuel mixture to compensate for lean or rich conditions. High positive fuel trim values suggest a lean condition, while high negative values suggest a rich condition.

5.4 Checking O2 Sensor Readings

Oxygen (O2) sensors monitor the amount of oxygen in the exhaust gas. Abnormal O2 sensor readings can indicate problems with the fuel system, exhaust system, or catalytic converter.
