I have a 2011 Sorento EX with 75,000 miles. It has the V-6 motor. I am the 2nd owner so my warranty is up. My check engin light has come on so I had it checked. It's showing code P0200. I had them erase it and it came back on 4 days later. I know what P0200 code is but I'm having none of the symptoms. Vehicle is running great with no hesitation. I'm still getting the same MPG. no raw gas smell. I checked the wires leading to the fuel injector on the rail facing vehicle grill and found no issues. I can't figure out the issue. Should I just bite the bullet and let Kia check it?

Possible Solutions

1. If you have multiple misfire/injector codes, a good first step is to unplug all the fuel injectors and then turn the ignition on, engine off (KOEO). Check for presence of battery voltage (12 Volts) at one wire of each injector connector. If all are missing, check for continuity to ground on the voltage circuit by using a test light connected to positive battery and probe each voltage feed. If it lights up, then there is a short to ground on the voltage feed causing a short. Get a wiring diagram and repair the short on the voltage feed and reestablish proper battery voltage. (Don't forget to check for a blown fuse and replace as necessary). NOTE: It's possible for one injector to short out the whole battery voltage feed to all the injectors. So if you have lost voltage to all the injectors, replace the blown fuse and plug each injector in, one by one. If the fuse blows, the last injector you plugged in is shorted. Replace it and retest. If only one or two battery feeds are missing, then it's more likely to be a shorted battery voltage feed in the individual injector wiring harness. Inspect and repair as necessary.

2. If you have battery voltage fed to each injector harness, then the next step is to get a noid light to check for injector driver operation. A noid light will insert into the injector harness in place of the fuel injector and flash rapidly when the injector driver operates. Check each fuel injector connector. If the noid light flashes rapidly then suspect the injector. Ohm each fuel injector if you have a resistance specification. If the injector is open or the resistance is higher or lower than the spec, replace the fuel injector. If the injector tests out, the problem is likely an intermittent wiring problem. (Remember that a fuel injector can work properly when cold but go open when hot, or vice versa. So it's best to do these checks when the problem is occurring). Check the wiring harness for any chafing, or the injector connector for loose pins or a broken lock. Repair as necessary and retest. Now, if the noid light doesn't flash, then there's a problem with the driver or the driver circuit. Unplug the PCM connector and ohm the fuel injector driver circuits. Any resistance means there's a problem. Infinite resistance points to an open in the circuit. Find it and repair it, then retest. If you can find no problem with the harness and there is no fuel injector driver operation, then check the PCM powers and grounds. If they are okay, the PCM may be at fault.

I'm going to try that but the problem is how to you get to the back bank of fuel injectors? The front bank is easy to get to.

This code may also indicate clogged/sticking injector(s). Suggest you trying running a FI cleaner as a possible (and easy) fix. Recommend two tankfuls of Techron to see if this helps clear things up.

I will surely try this first. I have the tools for this also. Lol
