Solution

1. Preparation

Gather tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool before starting work.

2. Address Diagnostic Trouble Codes (DTCs)

Sub-step 1: Interpret the DTCs obtained from the OBD-II scanner.
Sub-step 2: Research specific fixes related to the codes, such as replacing faulty sensors or components.
Tools Required: OBD-II scanner, service manual for code reference.

3. Replace Faulty Components

Sub-step 1: If the DTC indicates a faulty oxygen sensor, locate the sensor in the exhaust system.
Sub-step 2: Use a socket wrench to remove the old sensor and install the new one, ensuring it is properly torqued (typically around 30 ft-lbs).
Tools Required: Socket set, torque wrench, oxygen sensor.

4. Clear DTCs and Reconnect Battery

Sub-step 1: After repairs, reconnect the negative battery terminal.
Sub-step 2: Use the OBD-II scanner to clear the DTCs and reset the check engine light.
