I have a 2001 Toyota Camry V6 engine. My check engine light came on while i was driving on a side street. The codes that came up were P1135 and i think P0135. It came up as a air/fuel ratio sensor. I replace the sensor closest to front of the car (the one between my engine and radiator) but the light keeps coming back on after i reset it. I even tried unplugging my battery. Any help would be appreciated! :confused:

i believe P1135 relates to AFR heater on rear bank sensor (by firewall), not by the front of car.

P0135 is Heated Oxygen Sensor Circuit - Bank 1 Sensor 1.

Personally, I'd replace them in pairs because you'll soon get a P1155 or even a P1153 for the one on the front bank (closest to the radiator).

Denso 234-9021 (2001+ only) at Amazon is around $106.

OE spec, but not an OE/stealership price. Not sure if you already knew that.

If they're interchangeable, I'd opt to see that that error goes away by swapping in the new one. If it fixes it, go ahead and budget for the other. . .

just my poor 2 cents...
