Review on Denso 234 9002 Fuel Ratio Sensor by Jamal Sandridge

Arrived very quickly! The product is perfect for my 2001 4WD Toyota 4 Runner SR5. My Check Engine and VSC lights have been cycling on and off with code P1135 for the past 5 months. My mechanic replaced the same sensor about 4 years ago and charged $384 for the sensor and labor. I couldn't believe how easy it was and it only cost me $101 and some of my time. It took me about 15-20 minutes in total and I just took my time. Didn't have to lift my SUV, but it was tight underneath. I would definitely recommend removing the bolt holding the cable connector for easier access as others have said. I tried without removing the bolt but there just wasn't enough room to loosen. I held one side of the fork with slotted locks and used a small flathead screwdriver to pry up the tab to loosen the fork. A few days earlier I sprayed the screws onto the PB Blaster sensor to make them easier to remove. I haven't had any problems, but then again, there just isn't a lot of room to work with. I would say that you don't need to leave this simple job to a mechanic if you have at least basic car knowledge. Buy this, do it yourself and save a lot of money,
