Component Inspection

  1. Reconnect FTPS connector
  2. Ignition "ON" & Engine "OFF".
  3. Measure voltage between terminal 2 of the sensor harness connector and chassis ground (Do not disconnect FTPS harness connector)

    Specification : Voltage increases proportionally with decreasing pressure (Approx. 2.5V to 4.5V)

    PRESSURE CHART

    Pressure -3.75kPa (-1.10inHg) 0 kPa (0 inHg) 1.25 kPa (0.37 inHg)
    FTPS output voltage 4.5V 1.5V 0.5V

  4. Is voltage within the specification?

    YES 

    • Check for poor connection between ECM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure

    NO 

    • Check FTPS for contamination, deterioration, or damage. Substitute with a known-good FTPS and check for proper operation. If the problem is corrected, replace FTPS and then go to "VERIFICATION OF VEHICLE REPAIR " procedure
