P1135 and P 1155 What do these mean and what next??

P1135- A/F Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)

P1155 - "A/F Sensor Heater B2S1 Circuit Malfunction

DTC Detecting Condition

When the heater operates, heater current exceeds 8 A (2 trip logic detection)

Trouble Area

-Open or in heater circuit of A/F sensor (bank 1 sensor 1)

-A/F sensor (bank 1, sensor 1) heater

-ECM

What year/model? Also why did you have those sensors changed? Was it for the same codes? Could just be your light needs to be reset? I had the same codes on my camry due to the AF sensor in B1S1... After recieving and installing a defective sensor from oxygensensors.com I came to find out that it was covered under warranty at toyota... of course i felt stupid but at least i didn't have to buy another sensor.

After you changed the sensors did you reset the code with the scanning device? There is a simple 2 minute procedure to do this.

2001 RX 300 replaced o2 sensors because of 02 sensor codes. Now can't get the warning lights to go off.

took it to be re-scanned and these were the codes that came up

the relay for the heater circuit is most likely bad. about $45 from yota
