Super quick delivery as expected from Amazon and a super price - half the cost of the same item with a Toyota label on at the dealers.This fixed error code P1135 on my 2001 Rav 4 and took just a few minutes to fit with a 22mm spanner / wrench.

My daughter's 2003 RAV-4 Check Engine light came on recently -- error code showed P1135 (Upstream Left Air/Fuel Ratio Sensor). I replaced it with the Denso 234-9023 sensor from Amazon and it fixed the problem.I also ordered the Tektron 4929 oxygen sensor socket from Amazon (about $7) at the same time as the sensor. It made the job simple - less than 10 minutes! The sensor is located on the driver's side near the radiator and is easily accessible from the top. Use the socket with a 3/8" breaker bar. There is no need to remove anything to access the sensor. Be sure to use the anti-seize compound that comes with the sensor and don't over-tighten the new sensor.

Worked great on 2001 toyota rav4. fits sensor 1 position 1 (in the usa that is the top drivers side sensor). first i read the trouble codes with scangauge II , bought the appropriate oxygen sensor , replaced it, cleared the code, and i haven't had any trouble since. before the rav was stumbling really bad on acceleration and not much power.a week later i pulled out the mass air flow (maf) sensor and cleaned it with maf sensor cleaner because the scangauge was giving me 2 new codes about lean mixture. i used half a can on that sensor. i cleared the codes and haven't seen them since. rav runs great now. i am about to pull the fuel injectors and get them cleaned because the car has over 80K miles on it so i know they need cleaning. i found out you should clean the maf once every few years depending on your environment because air filter lint and other contaminants can built up on it. the maf is actually a combo of maf and iat. i have pics but i will post later. the scangauge2 works great by-the-way , well worth the money. oh, rav is getting 29mpg on highway with the tires at 55psi. can't wait to see what i get with clean fuel injectors. i'll probably clean the throttle body when i remove the injectors i am sure it needs it.
