OBD code P1330 on 2003 Kia Sorento?

P1330 = Spark Timing Adjust

Appears to be indication of a connector problem, wiring harness problem or ECM problem.

If the ECU/ECM is already replaced.

Then its spark timing adjustment problem.

The ECM computes ignition timing in response to the signals from several sensors. The timing is fixed during the start-up phase. However, when the engine has been started and the vehicle is driven away, the ECM computes the optimum timing based on the engine speed, load and temperature.The ignition timing is fixed BTDC 5 and DTC P1330 is set when connecting Ignition control terminal of Data Link Connector and ground. If disconnect Ignition control terminal of Data Link Connector and ground, the DTC is erased automatically.Make sure to check for short circuit to ground between Ignition control terminal of Data Link Connector and chassis ground when DTC is set.
If the ignition control terminal of the Data Link Connector is grounded, the ECM determines that a fault exists and a DTC is stored.Need to check this next.

Check resistance from pin no.19 on the DLC to ground.If that wire is grounded,then you have to fix that wire.
This will help.
