Fuel Tank Pressure Control Solenoid Valve (FTPCSV)

  1. Turn ignition off. Disconnect FTPCSV harness connector. Using an ohmmeter, measure resistance between terminals of FTPCSV. Resistance should be 30-34 ohms Swift, or 28-36 ohms on Vitara at 68°F (20°C). Resistance between each terminal and body of solenoid should be one megohm or greater. If resistance is as specified, go to next step. If resistance is not as specified, replace FTPCSV. Retest system.
  2. Blow into port "A". Air should flow out of filter. See Figure . Use fused jumper wires to connect battery voltage and ground to solenoid valve terminals. Blow into port "A". Air should flow out of port "B" and not to filter. If FTPCSV operates as specified, check for an open or short circuit between FTPCSV, ECM/PCM and main relay. See WIRING DIAGRAMS article. If FTPCSV does not operate as specified, replace FTPSCV.
