5Just what I needed
By A. Miller
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!

5OEM Part, Works Great... Cheapest Price Around
By A. Silva
This is an OEM Denso front Oxygen Sensor. I installed it in my '01 Toyota Tacoma 4x4(3RZFE 4-Cyl) and it plugged right into the OEM wiring plug plug for the front O2 sensor.. perfect fit. It also comes with the oxygen sensor gasket, which is an added bonus because that part sells for $6 at the Toyota dealership.

5Denso is factory OEM
By Patrick H. McMurray
My 4runner had 70,000 miles when the oxy sensor coded. Average is around 75,000 miles. The sensor ahead of the cats-california models had 2 catalytic converters and is also called the "air/fuel sensor" on those- is usually first to go.Replacement is basic. Now the annoying "check engine" light is off, and the engine is running per spec. Denso is considered the best replacement brand by most toyota fans.
