Component Inspection

2010 Kia Rondo LX, 2.7 6SECTION Component Inspection
  1. Check FTPS
    1. IG "OFF" and connect scantool to DLC (Data Link Connector).
    2. Monitor "FTPS" parameter on service data
      1. Specification:
        PRESSURE AND VOLTAGE SPECIFICATION CHART

        Pressure (kPa) -3.75 0 1.25
        Voltage (V) 4.5 1.5 0.5
    3. Is the "FTPS" parameter on the service data OK?

      YES

      1. Go to " 2 Check PCM" as follows.

      NO

      1. Substitute with a known-good FTPS and check for proper operation.

        If the problem is corrected, replace FTPS and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

  2. Check PCM
    1. IG "OFF" disconnect FTPS connector
    2. Connect scantool and IG "ON" & ENG "OFF"
    3. Select simulation function on the scantool.
    4. Simulate voltage at terminal 2 of FTPS harness connector.

    5. Does the signal value of FTP sensor change according to simulation voltage?

      YES

      1. 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

      1. Substitute with a known-good PCM and check for proper operation.

        If the problem is corrected, replace PCM and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

        CAUTION: There is a memory reset function on the scantool that can erase optional components automatically detected memorized by the PCM. Before or after testing PCM on the vehicle, use this function to reuse the PCM.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
