P1135 2000 4 cyl
 

CEL is on. Scanned code came back with P 1135. Can i get a little help on this? From some little research i see this is a Bank 1 Sensor 1 O2 sensor.

Does anyone know what I need to do to fix this (whats parts ill need to purchase specifically and approximate cost). Thanks in advance for anyones time.

Looks like you have a problem with the heater circuit at your air/fuel ratio sensor. This is a fairly common issue- that in most cases is cause by a failed heater within the sensor itself. If you decide to change the sensor on your own- be sure to buy the part from the dealership. Your car needs an air/fuel ratio sensor- NOT AN 02 sensor. They look the same but work differently and are NOT INTERCHANGEABLE.
