★ Top Answer
The error code p1442 in a 2005 Toyota Sequoia indicates a problem with the second air injection vacuum valve being stuck closed. This prevents the correct amount of oxygen from entering the engine, leading to a rich or lean air-fuel mixture. As a result, the engine will not run efficiently and could exhibit symptoms ranging from sluggish performance to stalling or difficulty starting. Ignoring this issue, even if seemingly minor, can cause costly damage to the engine. It is advisable to have the car checked by a professional if this error code appears.
