Hi, welcome to Just Answer. I'm acuramstr. this code is for the secondary oxygen sensor heater . is your car a 4 cyl or a V6?
heres what the sensor looks like it's under the car bu the converter . the connector is under the passenger seat. be sure to use a factory part the after market ones dont last and end up costing more in the long run.
