2G CEL Code: P0505

[vietdude]

I did a DTC Lookup for this code and it says Idle Control System Malfunction. Anybody idea how to fix this? thanks in advance.

Ahh, another victim of the idle control failure. I went through this myself, and the best way to do it is to either buy a refurbished or new ISC. I know someone on here has the link for the repaired ISC, I can't seem to find it. Also try the dealer. It's kind of an expensive part, but a real easy install. Not really anyway around it. Some people leave their ISC unplugged, but I don't know how that works.

This is the same problem i had. It kind of putters when accelerating and the occational backfire. I had the same code come up can someone please fill us in where the ISC would be located.. Thank you in advance. Some guy from the shop said it would be 500 bucks to fix.

The auto idle speed control motor on your car is attached to the throttle body by 2 bolts and a 4 pin connector.

The sensor is located under your TB... lil black thing(brown in 1g). goes out alot on our cars.. Im havin the same prob.. ordered one off ebay should b here soon. real easy to change. 2 bolts .. one on eaach side.. 8mm rachet should do the trick. make sure u unplug the battery terminals u gotta reset the ECU for it to work right.
