Hi Everyone,

First time poster here. I uploaded a video for ease but in a nutshell the truck won't start unless the throttle plate is slightly open. Once the plate closes the truck turns off completely. I checked the TPS sensor and it reads perfectly but I don't know how to determine if it's the IAC valve or something else. Please let me know your thoughts on this. Thanks.

 

Getting a P0505 code??? That's IAC circuit. If the check engine lite ISN'T on, could try cleaning the throttle body.... Disconnect the battery, physically remove the throttle body, remove the IAC valve, and clean all the passages. Carb cleaner works pretty good, compressed air doesn't hurt either. Once you have it squeaky clean, reinstall everything, hook the battery back up, turn the ignition to On, (not start), count to 10, THEN start the engine. PCM should figure out idle pretty quick.

 

Cleaned the IAC valve and the truck started right up; thanks for the suggestion.

 

Gotta love the easy ones.

 

I worked on this for 3 weeks and was about to call the scrap yard. I checked spark, fuel and only assumed their was air coming in. All my previous vehicles had a screw to keep the throttle body plate open and I thought the Dakota had the same. I made one last effort to fix the truck and checked the air coming into the engine as a long shot. Wedged the plates open the she fired right up.

Thanks again for the help. Saved me $10 - $15 grand on buying another truck.

Regards,

 

I know I'm in the wrong place to ask this but I got a problem. 2001 Dodge Dakota V-6 Got a series of oddball electric problems. The only thing they all have in common is they go thru the electric module.under the kick panel on the drivers side. I can't find one local but was wondering where I might look .VIN #1B7GL2X61S208046
Thanks if anyone can help. I love the old thing and when its running it's a bear.

 

Car-part.com. They can tell you who has the right year truck, then CALL them, see if they have what you need. Having the part number handy doesn't hurt either.
