Thank you for trusting Just Answer. What code did you have to begin with, and which sensor did you replace?

its ford windstar 1999 3,8l first from the engine
Did you have a check engine light on prior to this? What was the code?

yes it was P0171 P0174 and when i changing o2 sensor i also change heater sensor
Ok, first off, in the battery junction box, right next to your battery. There is a 15A fuse number 19. It is most likely blown. Did you replace the O2 sensor with the proper one now? Factory replacements are recommended here to avoid these problems.

yes i replace o2 with a new one 4 wires same as old one
You said you replaced sensor heater? The heater is part of the sensor. That is why there are 4 wires instead of 2. Replace that fuse and retest.
