I need the right information. What liter size engine?
Mid-size Cherokee or Grand cherokee.

Cost is going to vary. Testing should be done first in the event the oxygen sensor heaters are okay. That will run $35-150 as a guess. Depends on the shop and how they bill.

The same remains true for the part replacement. Shops have unique mark-ups on parts and labor charges may be actual time or book time.

If I were to confirm that it is 3 bad o2 sensors within an hour, then I would charge approx. $475 plus tax.
