i had found a problem with a kia rio. it was saying tps sensor but after a couple of hours and alot of cursing it turned out to be the maf mass air flow sensor. these are expensive so i suggest that you take it to a kia dealer to have it tested or find someone who can do it for alot cheaper

SOURCE: No spark, 1988 Toyota Camry 3SFE 4cyl, 5 speed.

there is no crank sensor on this vehicles 2.0L. If you have power to the coil, new coil, cap and rotor try this if not done yet>>>Unplug coil power first....Try pulling off the distributor cap, and make sure the rotor is spinning with the cam...If this fails to spin, inspect the entire distributor assembly. If it passes, Inspect all the power circuit and wiring to the dist assembly, if ok possible ecu. i recommend having a mechanic check it out!! Hopefully this helps...please rate...thanks

2005 Kia Sedona 3.5 eng. will not go over 15 mph with pedal to the floor cleaned the throttle with spray cleaner and did CPS two weeks ago and coils and tune up last night still same problem


I would recommend a scan test on the ECM to see if any trouble codes are there and point you in the right direction. The MAF sensors on thesr vehicles are problamatic and cause throttle actuator to go into limp mode. Unplug the MAF sensor and see if it makes any difference

Will not run over 25 mph


check your speed sensor and your crank position sensor. I did a clutch job on my RIO and forgot to plug the crank sensor in all the way and it wouldn't go above 25 Mph. If that doesn't work, try replacing your Mass air flow sensor, it sets on top of your throttle body and bolt to your air box.

The first you should be taking when getting error code should be to replace the faulty spark plugs and their respective wiring. Also check for faulty distributor and ignition coil. If everything till now is fine then and only then go for cleaning throttle body.

It almost sounds like you have a bad crank position sensor. Is the check engine light still on? Do you know what the codes are, if any? I see where it told you about the coils/misfire, but no other codes were stored?
