I have a 01 Lexus IS300 , my OBDII reader show these three code P0135 ,P0141 and P0155 , and they happen to be O2 Heater , so I went ahead and changed out the o2 sensor, I purchased a Bosch universal sensor 4 wires. ( well, I bought them online and they happen to be 4 wires o2 sensor for ford , but then I assume all 4 wires sensor are the same ...and I realize that the heater resistance are different between car , correct me if I"m wrong) as a result the code still pop up , so then I tried to trick the computer by use the working sensor which is the B2S2 ( no code appear to be for the sensor) so I shared that Heater signal to all other sensor, drove for 120miles no code and the CHK engine light come back on again, now it pop a code for P0161 .... I'm so confused and tired of this engine light... can somebody help me
I haven't measure the Universal (ford) Bosch O2 Sensor heater resistance but I have been reading up they are about 4-8ohm.... the FSM said it should be at 11-16ohm , can I trick the ECU by adding a resistor to it ? or I really have to get the Denso O2 sensor?
are all the Denso sensor heater resistance from 11-16ohm?
