The day after I bought my CR-V, the check engine light came on, approximately 50 miles on the car. The dealership tested the light, and found it to be a faulty ftp sensor, which they replaced off of another CR-V on the lot. Since the day after I bought my car, I have had the phantom check engine light coming on and off about every month. I brought my car into another Honda dealership in March 2012, and they found the ftp sensor was causing the check engine light to go on, but could not identify where in the sensor was bad. They cleared the code, and all was fine for about another month. The light came back on again a few weeks later, but when I got to the dealership, the light had gone off as I pulled into service. April 6, the check fuel cap light was flashing(which seems to happen everytime the light is about to go on) and the check engine light went on April 7. took it back to the dealership again for the 4th time.they said I had yet another bad ftp sensor, and replaced it again, this time with a new part in stock. This has been an ongoing issue since the car was bought, and is effecting my gas mileage. Right before the light goes on, my mileage goes from 27 mpg to around 22mpg.
