Kia Sedona (2008 year). Instruction — part 113

5. Does "UD SOLENOID DUTY" follow the reference data?

YES



Fault is intermittent caused by poor contact in the sensor's and/or TCM (PCM)'s connector or was
repaired and TCM (PCM) memory was not cleared. Thoroughly check connectors for looseness, poor
connection, bending, corrosion, contamination, deterioration or damage. Repair or replace as necessary
and go to "VERIFICATION OF VEHICLE REPAIR" procedure.

NO



Go to "TERMINAL & CONNECTOR INSPECTION" procedure.

TERMINAL & CONNECTOR INSPECTION

Refer to DTC P0750.

POWER SUPPLY CIRCUIT INSPECTION

1. Disconnect "A/T SOLENOID VALVE" connector.

2. Measure voltage between terminal "5" of the sensor harness connector and chassis ground.

3. Turn ignition switch OFF --> ON.

Specification: 12V is measured only for approx. 0.5sec
