OK, this is my sister in law’s van. She has done very little in way of maintenance as far as I can see. Currently, it is sitting in my driveway where it has for the last 4 to 5 months, and I am looking for any ideas on problems to get it out of my way before winter… When it first got here, it w…

Why did you replace the fuel pump? Was this a guess or did you check the pressure with a gauge? Either way, checking the fuel pressure is a must. Did it get a new fuel filter? How about an air filter? If you have a vacuum gauge you can check it for exhaust blockage. If you don’t try pulling th…

we replaced fuel pump as we also thought of the fuel filter being clogged however the nice little filter is in the pump so it got a whole new pump

ok gang I broke down and got a computer scanner. the code it came up with was for a intake air temp sensor but no auto part store has one… where do i get one??

You would call Kia. Or use the internet to find one. Tons of parts on the internet. There’s little that you can’t get from rockauto.com , for example. Do you even put a fuel pressure gauge on it? Check for exhaust blockage? No code will tell you that a sensor is bad. What was the exact code? …

FWIW, Would A Bad TPS (Throttle Position Sensor) Cause All These Symptoms ? Does this vehicle have a 3.5L engine ? A Kia Technical Service Bulletin (written for Kia technicians) indicates that TPSs on 2002 - 2005 Sedonas with the 3.5L engine can have TPSs that go to hxxl in a hand basket (suffer f…

I will try to answer all of these questions… first it is a 3.5 tried to get to the bulletin above but cant? How did you get to it maybe I am doing something wrong there… Dont have a vaccuum gauge but did pull the o2 sensor and no change in it… we did take the mass air flow sensor off and it idles…

You still need to report the actual, specific code. The “high” in the code description will not refer to high temperature. It will refer to high voltage. E.g. the code P0113 just means that the PCM saw an air intake voltage higher than 5V. This is bad b/c the PCM only ships the sensor 5V - the…

ok thanks for all but it will be sat before i post again and have time to look at it some more

well I managed to get off work early and played with this van again… first i plugged back in the o2 sensor, cleared all codes on computer and rescanned… only thing that came up was po123 throttle/pedal position sensor/switch a circuit high. what’s our best guess???

An intake air sensor is not going to cause a vehicle to be anemic.
I’d suspect a large vacuum leak or a clogged catalytic converter. A vacuum gauge should reveal if either one of these conditions exist.
