Inspection Procedure

HINT: 

• When viewed from the rear of the engine assembly, Bank 1 is on the left side and Bank 2 is on the right side.
• Read freeze frame data using the Techstream. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.
