With the little info you gave, not telling us if the check engine light is on? Did you have the car scanned for codes? if so what are they? Engine size? Mileage? does it feel like the transmissions not shifting? engine running rough? ECT. I will leave you with this… [Hyundai Elantra: Transmission Not Shifting! Severe Engine Power Loss! No Check Engine Light On - YouTube](https://www.youtube.com/watch?v=8dCjBbIFiOA) ---

It would be a very big & expensive job to replace all the sensors the car uses. I doubt that happened. Suggest to tell us exactly which sensors were replaced, and why. Likewise, explain what you mean by “loss of power.” Which of these? - Car wouldn’t accelerate as quickly? - Car wouldn’t move? - Engine wouldn’t crank? - Engine would crank ok, but wouldn’t run? - Battery went dead, no electrical power? Besides the other info requested by WW above, suggest to also post the car’s engine & transmission configuration. ---

Proof once again that randomly throwing parts at a problem rarely fixes it! ---

> [@OPENATION](#): > > I replace all the sensors in the car and still the same. 1. I really doubt you got them all. 2. The cost of “all” the sensors probably exceeds the value of the car 3. Good luck. ---
