Did you reset the trouble light after changing out the sensors? It'll take a long time for them to go out by themselves. How does one reset the trouble light....?? You'll have to take it to a place like Autozone (or your dealer) and ask them to reset it using their diagnostic tester. Autozone should do it for free. So much for fixing this stuff by yourself! After 2 diiferent garages charged $170 and $85 for their computer diagnostices the end diagnosis is "bad ECM" and after $1000. bucks to replace that...now they tell us the bad ECM toasted the new 02 sensors...which will now have to be replace again. Goota love these foreign cars.,.

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 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.
