Clearing a DTC will reset the check engine light, but it’s important to address the underlying issue to prevent the code from returning.

According to the Society of Automotive Engineers (SAE), standardized DTCs are essential for accurate and consistent diagnostics across different vehicles.

3.2 Monitoring Live Sensor Data

Live sensor data provides real-time information about your car’s performance. This can include:

• Engine Speed (RPM): The rotational speed of the engine.
• Coolant Temperature: The temperature of the engine coolant.
• Intake Air Temperature: The temperature of the air entering the engine.
• Oxygen Sensor Readings: The amount of oxygen in the exhaust gases.
• Fuel Trim: Adjustments made to the fuel mixture by the engine control unit (ECU).

Monitoring live sensor data can help you identify problems that may not trigger a DTC, such as a failing oxygen sensor or a vacuum leak.

According to a study by the National Institute for Automotive Service Excellence (ASE), understanding live sensor data is a critical skill for automotive technicians.

3.3 Using Freeze Frame Data

Freeze frame data captures a snapshot of the sensor data at the moment a DTC was triggered. This can provide valuable clues about the conditions that led to the problem.

Analyzing freeze frame data can help you narrow down the possible causes of a DTC and identify the specific component or system that is malfunctioning.

According to a training manual by Bosch, freeze frame data is an essential tool for diagnosing intermittent problems.
