Check to make sure the o2 was put in correctly.. if it is the same there should be an issue.. if after market try using a bigger fuse but not one rated higher then the wires which is 25amps i think.. if it still blows then put the old o2 sensor back in and see what happens good luck..

Hi! Yes it would keep it from starting so I strongly suggest that you have it looked by your trusted mechanic for this will require on hand trouble shooting for grounded wires. HOpe this helps and thank you for using FixYa!

1999 hyundai sonata. bank1 sensor1 o2 heater circuit malfunction. I think that there may not be a pulse coming from pcm.what else could it be


this is fairly common with these o2 sensors. replace the one that has failed. they have a 4 wire set up that incorporates a circuit for a preheater that warms up so it reads more efficiently and even controlls emissions at start up. there is a fuse under the hood on the left side for o2 sensor heater circuit. check this first and then replace if necessary.

The not ready may be for a HEATED O2 sensor and HEATED catalyst. Since these cars are not equipped with the HEATED versions, they would never be ready.

2002 Lancer OZ Rally...


I had the same problem with my 2003 Lancer OZ. The oil level and pressure were ok. Car was fine with no light when starting. After 10 to 15 mins of driving it would come on when I was stopped. It would go away when I pressed accelerator. Try replacing the Oil Sending Unit. It's about $10 and easy to swap. That was my problem.
