Pulling Codes: The Story of Codes P1128 and P1129

It was Saturday, June 11, 2011, at 8:30 in the morning. I had just arrived at an automotive repair facility located in Merriville, IN, owned by a very good friend of mine.

Tech Tip: Kia Has Intermittent MIL On with No Fault Code Stored

In affected vehicles, an intermittent short to ground in a circuit only intended for testing purposes may cause the MIL to illuminate and a DTC P1330 (Spark Timing Adjust) to be stored.

Tech Feature: Kia Driveability Diagnostics

We’ll be taking a look at the Kia line of cars and SUVs this month with an eye toward driveability issues and check engine light concerns.
