Answer
The EE26 is the one you want to worry about . This code is caused by a shorted throttle switch circuit in the idle speed control motor. There is a diagnostic chart and specific instructions to test and replace and adjust this ISC motor. I can provide you with all the documentation. E-mail me at;
