I have a code P0141 which is the o2 sensor heater circuit malfunction is there any way to check the circuit for a bad connection or any way to solve the problem without taking it to the dealer i would appreciate some help since the search is not working. Thanks

 

A heater failure is usually simply a faulty wire or O2 sensor.

where are the heater circuit wires located?

 

^ there is four wires going to the o2 sensor. Im not sure exactly what colors are what but you will see all four going into the actual sensor.
