Light doesn't clear
SOURCE: where is the b1 s1 o2 sensor located on my 2003
bank 1 sensor 1 il locates right infront of the catalytic converter . bank 1 sensor 2 is located in the catalytic converter
SOURCE: Check engine light is on and it shows code P0032
P0032 - Oxygen (A/F) Sensor Heater Control Circuit High (Bank 1 Sensor 1)
A P0032 DTC (diagnostic trouble code) refers to the O2 sensor (oxygen sensor) located on Bank 1 in front of the catalytic converter. There is also an oxygen sensor behind the converter which is Sensor #2.
This O2 sensor #1 may also be refered to as an air/fuel ratio sensor since on some vehicles it is. The sensor detects the amount of oxygen in the exhaust gas compared to the outside air and then vehicle's computer adjusts the air/fuel ratio going into the engine. The sensor is less effective when the exhaust gas temperature is low, so it includes a heater which is activated to help get better readings from the O2 sensor. Essentially this P0032 code means that the resistance of the heater circuit is higher than normal. In some cases, that resistance level must be higher than 10 A to trigger the DTC code.
Note, this code is very similar in nature to P0031, P0051, and P0052
Most likely you'll not notice any symptoms other than the MIL (malfunction indicator lamp, a.k.a. the check engine light) will illuminate.
A P0032 DTC trouble code may be caused by one or more of the following:
A short in the heater circuit in the sensor
A failed O2 sensor heater
Wiring/connectors broken/frayed leading to sensor and/or relay
Failed PCM/ECM
I hope this helps, abd just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment. Have a nice weekend and thanks for using FixYa.

Check your wires. You may have a bad connection or broke wire. other than that you may have an issue with it running too rich or lean. The o2 sensor will turn on the check engine light if its out of specs.
