Hell-o my name is Steve, I own a 2002 Toyota Rav4 automatic with 110,000 miles on. The other day the check engine light call on , plugged in my scan-tool and got code P1135, I changed the O2 upstream sensor on right side of engine but light comes back on. I need some help, thank-you, Steve

You may have change the wrong one, bank 1 sensor 1 in your case is the one on the driver's side. BTW, it is an A/F sensor.

N.E.O.

You are right about that being a A/F sensor, The sensor that I changed is on the driver's side. Thank-you, Steve

So you did change the right sensor and the light is still on?

N.E.O.

Yes the light came back on same code P1135

Did you use a Toyota sensor? Did you check for 12V across the terminal for the heater circuit of the connector?

N.E.O.

Bosch sensor, Sorry but it's all I could afford, I will check for 12 volt at the plug tonight, Thanks for your insight, Steve

Check and compare the heater element resistance between the two sensors, the Toyota one and the Bosch one. It is possible the resistance value difference causing higher draw in the Bosch sensor.

N.E.O.

Hi Steve, welcome to the forum

Hi,

I have a 2002 Highlander (V6) and I had a code of p1135. I replaced Bank 1 Sensor 1 with a new Bosch AFR Sensor.

The check engine light and VCS light went off, but now when I start to drive only the VCS light comes back on.

I checked again for codes and there were none. The dealership was confused about this as if there is a problem a code should could up. I don't want to bring it to the dealership and pay $$ to find out nothing is wrong.

Could this be related to using a Bosch sensor vs Denso?

Any help would be appreciated.
