Just what I needed

Like Javier, I had “Check Engine” and “VSC Trac” lights on a 2001 Toyota 4Runner. Had an auto parts store pull the code (P1135) from the truck’s computer, and decided to shop around when they wanted $200 for the part. I saved about $70 by buying the part here and probably $60-80 more by doing the repair myself. It’s not a bad job, especially if you search online for a how-to. The hardest part was actually unplugging the connector on the old sensor. Looking at the new sensor helped me to figure out how to do it; basically I used a small screwdriver to lift up a tab that locks the connector into place. Also, once the new sensor is installed you may need to disconnect the battery in order to reset the computer and turn off the check engine light. Once I did that, the problem was fixed!

Worked perfectly

I saved about $70 with this purchase. I replaced the bad Oxygen Sensor on my 2001 Toyota 4Runner and the Check Engine light and VSC/Track light when off. It worked perfectly.
