Hi, my EML came on and scanning the car shows a fault in Bank 1 sensor 1.Advice would be handy in the cheapest sensor to buy and ones you have used. Many thanks.
That is the right hand top (pre cat) sensor.

I have the same problem, and indeed have replaced all four sensors in the past. I did a fair bit of research and took advice, both from our own tame mechanic, and another Toyota specialist, and offer the following advice. If you find that the fuel consumption has gone up, then the sensor is in the fail mode, and as a result the mixture supplied is richer, and thence more fuel used. The general advice is to replace all four sensors at once and do NOT buy cheap ones, but stick to the OEM make which is Denso. Using cheaper sensors can result in a problem or indeed a failure of the ECU, and that is pricey!! Also, with the fault light cleared, monitor the light, as there can be spurious warnings, and indeed, the manifolds of 2003 to 2005 cars were suspect, and the later models had modified manifolds. Here's a link to what I will probably be buying, and you will need the special tool if you fit them yourself, and do one at a tine as they are colour coded! www.ebay.co.uk/itm/BANK-1-BANK-2-LAMBDA-SENSOR-TOYOTA-RAV4-2-0VVTI-1AZFE-4-LAMBDA-SENSORS/303068436072 |

I bought one of those 'special' sockets waste of space, time & energy, they are a normal socket with the side cut out of the side to allow the cable to go through. They are great to install the sensor, as you only nip them up tight. But come to undo a rusted in solid sensor all they do is expand & then round off the sensor making them even harder to get out. If you are just removing them to throw away then just cut the wires & use a 'proper' 6 sided socket, if you need the wires & you can get a long ring spanner on go that way.

I use a Jubilee clip to keep the split socket tight to the sensor 'nut'. Socket on sensor, open Jubilee clip to slip over the wire and then re-assemble clip around socket and tighten.
