03 kia sedona ex was getting tps code, replaced that with 1 from auto store, although the guy put it on, and messed with idleing it down, van will slowly pick up speed downhill, lose speed up hill


The age of your kia warrants scan of the OBDII Fault codes with a print out (Autozone can do it). The TPS Should not effect engine speed Creeping up or down. Check the codes first to avoid buying parts you don't need. Also don't throw those coils away, the are probably OK. Check out some of my other post concerning drivability problems . Always start with cheapest fixes first.

I've pulled the OBD1 Codes, reading: 12, 13, 41, and 43. What's my next steps in troubleshooting malfunctions with Revolution signal (RPM), Throttle Position signal (TPS), and Starter Sensor


Lets start with - whats the make model and year ?
If it is a GM product, code 12 is system normal, 13 is a problem with the O2 sensor, 41 is a computer problem, and 43 is electronic spark control.
You could do a compression test to make sure all of the cylinders are normal as far as the valve train goes. Code 41 could cause the other codes and your performance issues.

I have a 99 Buick Regal, it hesitates and even stalls out. I had the oil and filters changed as well as the fuel filter. It is still hesitant and feels like it wants to dye. When I changed the fuel filter...


A combination of problems could be causing your hesitation/stall issue:
  1. Bad MAF (Mass Air Flow) sensor
  2. Bad TPS (Throttle Position Sensor)
Getting a free diagnostic test to pull codes will make narrowing down your problem a bit easier. Most chain auto parts stores will do a complimentary diagnostic test. The most common cause with a car that stalls when warm is the TPS. It controls your idling speed under all conditions. Even replacing the MAF alone doesn't always fix the problem although it may show up as being problematic. The 2 parts basically go hand in hand with your particular problem.

Car stalling


Did the 'Check Engine' Light come ON? Whenever the 'CHECK ENGINE' light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on. You'll need to use/find an OBDII (On-Board Diagnostic) Scanner to retrieve any code which have been stored in the ECU computer. Afterward, we might be able to help you DIAGNOSE and perhaps eventually fix the problem.
NOTE: Commonly, the throttle position sensor (TPS)can cause the symptom you describe without turning on the CHECK ENGINE light. The TPS is a simple dash-pot (potentiometer) which can develop problems with age/time. Recommend you find a mechanic/ electrician who knows how to test it for bad spots -- if they find any, replace it.

Jolting and throttle problems


what size engine? 2.4?... 2.7?... 3.5? each one has a different fuel delivery system. Was there a Check Engine Light when this happens? Whenever the 'CHECK ENGINE' (Service Engine Soon) light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on.

First impression is a MAP sensor. If you take the car to a service station or an auto parts store that features free diagnostic tests, I'm sure the MAP sensor fault will appear. Other cause could be the TPS which controls the idle at cold,warm, and AC operation settings. It's possible that you're stalling due to insufficient idle speed setting on the TPS.

My Kia Sorento won't gear down and accelerate when I floor it. Dealer says it's a sensor in the transmission and they need to drop the transmission ($400 labor) to replace the sensor. I have a feeling that...


TPS of Throttle Position Sensor needed adjusting and is the problem and not the gearbox.

This usually happens when the engine light comes on and the TPS is adjusted but most dealers forget (or maybe intentionally) to reset the gearbox P/TRN Fuse.

Whenever the engine light comes on the gearbox is set to run in Sick Slow mode which is why you have this problem.

Before doing anything, try pulling the P/TRN fuse for 5 mins and put it back. Then try the car.

Hope it works, i did for me.
