                Perfect fit for 2003 Rav4. Easy to remove & replace if you warm engine up first. Costly item $$$$. The 25% discount & free shipping sealed the deal!

                      A:

                      I'm glad to assist, K360ff! This Denso Direct Fit Air Fuel Sensor (Part No. 234-9023) is the correct sensor to correct the bank 1 sensor 1 code on your 2002 Toyota RAV4 2.0L L4. In 1993-2008 Toyotas with the following engines: 1AZ–FE, 2AZ–FE, 2AZ–FE (PZEV), 1GR–FE, 2GR–FE, 2GR–FSE, 2JZ–GE, 1MZ–FE, 3MZ–FE, 1UR–FSE, 3UR–FE, 2UZ–FE, 3UZ–FE, 5VZ–FE,
                      and 1ZZ–FE; Toyota indicates in a technical service bulletin that Bank 1 will include cylinder 1. Also, this Denso Air Fuel sensor interchages with NTK Part No. 24657 which is for cylinders 1 and 4.

                      Denso's use of the term "upstream left" can certainly be confusing here. When looking at the engine from the side that you can see the exhaust from it would be the right sensor.

                      When replacing a sensor in the exhaust, you may want to pick up an AutoCraft Offset Oxygen Sensor Wrench (Part No. AC679) and some rust penetrant such as, WD-40 Specialist Rust Penetrant (Part No. 300004) or PB B'Laster Penetrating Catalyst (Part No. 16-PB).

                  • Q:

                    I have a 2001 Rav4, 1998cc, L4, FI, Vin. 1AZFE. I am looking for a air/fuel ratio sensor. Your part no. 234-9023 & 9028 are listed as air/fuel sensors. If not please direct me to correct part no. My diagnostic tester indicated that A/F sensor in bank 1/sensor 1 is the cause of my check eng light being on. Do I need to replace both bank 1 & 2? Thanks Ed

                      A:

                      The exact direct fit replacement Air fuel sensor for your 2001 Toyota RAV4 should be the Denso Air Fuel Sensor Direct Fit with part# 234-9028 which is for Upstream Right and the Denso Oxygen Sensor Direct Fit with part# 234-4048 which is for Downstream Left. It is not necessary to replace both bank one and bank two sensors, if the diagnostic tester indicates that the bank one sensor is the cause of the issue.
