I am 17 years old and me and my dad are working on a 2003 Dodge Neon SXT. I found out how to check the engine code and everything I just need to find out what to do after I find out the problems. I need to know what is TPS, what do I need to do about the Idle Speed High, and the Engine Oil Pressure Sensor/Switch Circuit Low Voltage. If any one can help me it will be greatly appreciated thanks.

 

tps is teh throttle position sensor. and thats probably the reason your idle is crap. and id check wires going to the oil pressure sensor

 

yup Throttle Position Sensor...that will fix your idle...as for that low voltage??? hmm.....fix the TPS first and see if it goes away...if not then I have no clue except to ask 03NEONRT lol....but no..low voltage...replace the wires or the oil pressure sensor and switch themselves...they arent too expensive..

 

First make sure there is oil.ok the oil pressure sender is at the back of the block just above the the oilpan on tranny side. the plug has only one green wire make sure you did not hurt it or some thing
