Hi, everyone, we have a 99 sonata, having some weird issues, we are thinking its the pcv valve or throttle position sensor. Does anyone know where these are located? It's a 2.4L 4 cyl.

 

A. PCV Valve


----------------------------------------


The TP Sensor is a variable resistor type that rotates with the throttle body throttle shaft to sense the throttle valve angle. As the throttle shaft rotates, the output voltage of the TP Sensor changes. The ECM detects the throttle valve opening based on voltage change.

 

Thank you for your help, we appreciate it

 

I am going to post what the car is doing, and see if anyone has any ideas on what the problem could be....When driving the car, we were stopped, to make a turn, after the turn, we gave it gas, it seemed to jump hard (like being hit from behind) and then go fine, but as soon as you stop or slow down and have to give it gas again, it has no pick up to it. This has happened 3 times in the last week, not only after a turn, but also just driving, stopping at a light, and trying to go again. Does anyone have any ideas on what this could be?
