The 3.0L and 3.5L engines in the XG300, XG350 and Santa Fe incorporate a Variable Induction System (VIS). The VIS is a secondary set of throttle plates in the upper intake plenum used to increase low end torque while maintaining high rpm performance. The Powertrain Control Module (PCM) uses a Variable Intake Motor (VIM) to control the opening and closing of the additional throttle plates called the Intake Control Valve (ICV).
At low rpm the (ICV) is closed and, as rpm increases, it is opened a specified amount for optimum airflow.
A VIS system condition is not likely to affect drivability, however, a diagnostic trouble code (DTC) may set. The DTC for the VIS system is P1159 (Variable Intake Target Position). The PCM controls the desired valve position and when the feedback of the
valve position does not correlate with the requested position this code is set. This DTC will not turn the check engine lamp on, however the code will remain in memory.
NOTE: P1159 has been changed to P2015 for the 2005MY.
Please refer to DTC P2015 in the 2005 Shop Manual for further diagnostic information on P1159. (XG350: page FL-555) (Santa Fe: page FL-633)
DTC Strategy Target position monitoring • Poor connection
• Open or short to battery
in harness
• VIS Motor or VIS Motor
Rotation Sensor
Enable Condition Engine speed > 3750 rpm
Threshold Value Unable to obtain target value
Diagnosis Time Unable to obtain target position 4 times
MIL On Condition N/A

The VIM is not available as a separate unit from the upper plenum if replacement is needed, therefore the entire plenum assembly must be replaced.
NOTE: With the intake plenum removed, inspect the gear on the VIM to see if it has stripped. Carefully inspect the throttle plate retaining screws that attach the plates to the VIS shaft. If any of the screws are missing (2 screws per throttle plate) inspect for engine damage.
Once the intake replacement is completed (see appropriate Shop Manual for the vehicle you are working on) the Electronic Throttle Position System (ETS) should be re-initialized by turing the ignition key On and Off within 1 second. Then, wait 30 seconds before starting the vehicle. Refer to TSB 05-36-002 for the complete ETS
initialization procedure.

I have a 2001 xg 300 and now for over a year, the airbag light has been on. What's the deal?? I can't afford to take it to a dealer, I am ASE certified myself, I just want to know how to reset the light...

You have to fix the problem to reset the light. You need to have the dealers computer to find the problem. Could be an airbag bad, a bad clock spring, bad pre tensioners. If it has rear and side curtain, just add to the list.
