hi all,

my car is giving me code p1135 which i found out that this corresponds to A/f ratio sensor B1S1, which is located in the back of the engine before the cat. my problem is that i need help determining which sensor to buy as there are many types and don't want to get the wrong one. i went to amazon.com which has the best prices plus free shipping. i looked at the following but i'm not sure which one is the correct:

Denso 234-4622 Oxygen Sensor $70
Denso 234-9009 Air and Fuel Sensor $120
Bosch 15217 Oxygen Sensor, OE Type Fitment $101

please help me in making the correct choice.

get the one that is for bank 1 sensor 1, upstream its also called.

but, getting an 02 sensor just because you have a code for it is not 100% correct decision. you also shouldn't just replace one, but both upstream right now.

every website like rockauto.com tells you upstream or downstream, i dont know why you're troubling us to do so

bigflippa

not every website says upstream or downstream. about troubling you - - go >>>>>

PLEASE NOTE!!!!!!!!!!!!!!!!

O2 and AF are two DIFFERENT types of sensors, and can NOT be switched.

The AF sensor from the dealer is around $55 more then the O2 sensor. If your near Stamford, CT, I may be able to get the sensor from the dealer for around $175 for you if you get it.

asg14 thx for the offer, but unfortunaly i'm in NY. do you know if the Denso 234-9009 Air and Fuel Sensor is the right sensor for Bank 1 sensor 1 code p1135? i just want to get rid of the engine light.
