2006 Other Isuzu Models 4 cyl Four Wheel Drive Automatic 46400 miles
----------------------------------------------------------------
I was driving my 2006 Isuzu i-350 tonight and was going up a hill and it shut off on me and then the engine light came on. I shut it off, then restarted it. I took to an parts store and they hooked up their code reader and gave me this code. P2101, which i found out is the code for the Throttle Actuator Control Motor CKT range. perf. It is still under warranty but is this a real code or can i just reset it and it will go away?

Why would you think when the car dies, and the light comes on, the code would be false? Some of these parts are expensive! Get it done under the warranty
