A couple of days ago the check engine light came on. The next day, the RPM dial quite working and the speedometer work incorrect. I refueled with good gas and the next day the check engine light went off. However, the next day my wife went to pick up our son from school and when she tried to drive it, she said it acted like the parking brake was on. What could be the problem?

thanks for your help.

Thank you so much I wish I tried what you said because I took it into the shop and charged me 340.00 for the sensor replacement and I found the sensor for 45.98.
