My car is Sonata model 1994 automatic with 4 cylinder.
I have a problem in THROTTLE POSITION SENSOR (TP SENSOR) adjustment.
I have done the adjustment just like the instructions that is mentioned in the Service manual.
I used a digital voltmeter to measure the voltage between connector 1 and 3.the voltage is 480-520 mV.
I also disconnected the negative connector of the battery for 30 seconds.But it didn’t work and the car is not idling well now.
I have RPM fluctuation while idling.in Idling mode the RPM is about 1100.
I would greatly appreciate if you help me about this case and tell me the correct way for TP SENSOR adjustment.
Posted 09-10-2013, 06:55 AM Thanks for taking the time to create this thread. It answers a lot of questions and is exactly what we are experiencing now. Our '07 has acted up four times so far and I've just unhooked the battery after each time to reset the check engine indicator.
I'll have to take it to the dealer soon because the wife isn't excited by the prospect of the engine losing power on the interstate. We've only been back to the dealer once in 85,000 miles and it's something I dislike doing.
Seems odd to me that the vehicle warranty does not cover a known fault...... I called the 800 number and after ten minutes of nonsense and then five more minutes of waiting on line ......... They said "Nope... Not covered".
Thanks again for the info.
Posted 08-19-2014I know the thread is a year old ...... but I just paid $260. to have the $30. part installed ...primarily because of the new programming required.
The dealer also wanted $155. to replace the throttle body air hose assembly that was cracked. I ordered it from Amazon for $30. (Dorman 696735)
