You need to set the tps voltsge o that engine between .55 volts and .60 volts. with a voltmeter- check to find one of te three wires on the tps plug and find the wire that has less than 2 volts on it. the other two have 5 volts and ground. loosen the screws on the tps and rotate it until the voltage is arround .56 volts. - good luck

your talking voltage so i will assume you know how to use a voltmeter and how to check tps voltage.with the voltmeter connected if you loosen the sensor screws you can move the sensor a little maybe enough to lower the sensor voltage.some of these are not adjustable.
I saw exact same problem for few days. Now I see check engine light all the time and engine speed is normal.
The cruise control stopped working. Cruise control sign so nOT light up when I turn it ON. Nor does it works.
But car seems to work fine.
locate the throttle body and on the side match your new T.P.S sensor, its usually held on by 2 screws, torx kind, so you might have to buy that screw driver since it is not common. remove and disconnect the old one and install. if its adjustable you need to set it, with a voltmeter. if its not just make sure it engages and slides in fine.
Basically Theres to scews that hold it on and behind the sensor theres a lever.When you take it off do it slow.And remember the exact location as where the bolts tighten on it..As long as you put it in the exact position it will work perfect.Just remember the way it comes off put back same way on and you'll have no problems.
turn on car and use voltmeter on the sensor get the base reading then get a reading with the throttle partly opened and see if it increases or what. it could be faulty, if it is not within spec then get a new one, unplug the batter negative terminal and install new sensor. reconnect everything and you shuold be on your way!
There is a Turn Signal "Flasher" that should be on the Fuse Panel inside the Car. If not it will be in the Fuse Relay Box under the Hood. This is the Problem and needs to be Replaced. Let me know if you need more Help! Please Rate my Response, I need all the Help I can get! Thanks!
