Where is the oxygen sensor code p1155 located in toyota mini van sienna?
You need to a new oxygen sensor if you are getting a p1155 code on a 1998 Lexus. This means that heater circuit is malfunctioning.
Trouble code P1155 means: A/F Sensor Heater Circuit Malfunction
01 toyota salara oxygen sensor how to replace it code p1135 p1155
Trouble code P0136 means: HO2S-12 (Bank 1 Sensor 2) Circuit Malfunction
You probably put an O2 sensor where you should have an Air ratio sensor, they are different they only look similar but they are different internally.
Bank 2 sensor 1 Air fuel sensor heater circuit. This sensor is NOT an O2 sensor, though it operates like one and in the same location(in exhaust stream). Basically the PCM detected that the heater circuit was drawing excessive amperage or no amperage. Usually it's a bad a/f sensor and replacing it will fix it, however, it doesn't rule out the possibility of damaged wiring or an open in the power or ground circuit, or a short in the power or ground circuit.
sensor before the catalytic converter
Trouble code P0174 means:System too lean (Bank 2)
Trouble code P0172 means: System Too Rich (Bank 1)
Trouble code P0136 means: HO2S-12 (Bank 1 Sensor 2) Circuit MalfunctionThis means that your o2 sensor (oxygen sensor) after the catalytic converter is faulty. This can either be the wiring and circuit itself or it can be the actual sensor. (9 times out of 10 for me, it is the sensor itself). The wires are well protected and unless they've been messed with before they should never be harmed!
That code indicates a fault in the 'downstream heated O2 sensor' , bank 2.That code indicates a fault in the 'downstream heated O2 sensor' , bank 2.
