Tank Pressure Control Solenoid Valve (TPCSV)
- Disconnect hoses from TPCSV. TPSCV is located on intake plenum chamber. Disconnect TPCSV harness connector. Using an ohmmeter, measure resistance between terminals of purge valve. Resistance should be 33-39 (Esteem), or 30-34 ohms (Swift) 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 TPCSV. Retest system.
- Blow into port "A". Air should flow out filter. See Fig 1
. Connect battery voltage to solenoid valve terminals. Blow into port "A". Air should flow to intake manifold. If TPCSV operates as specified, solenoid valve is functioning correctly. If TPCSV does not operate as specified, replace TPSCV.
