EVAP System Leakage Check

  1. Disconnect purge hose from intake manifold and fuel tank pressure control valve hose from solenoid vacuum valve. Plug EVAP canister air valve hose end. Connect scan tool to Data Link Connector (DLC). Select MISC TEST mode. Turn canister purge valve on using scan tool. If scan tool is not available, Using fused jumper wire, ground ECM/PCM terminal C21 terminal No. 7 on Esteem and Swift, E91 terminal No.26 on Esteem 1.8L, C51-2 terminal No.17 on Vitara 1.6L and 2.0L, C51-2 terminal No.1, on Grand Vitara 2.5L, and C51-1 terminal No.15 on XL-7. See PIN VOLTAGE/CIRCUIT RESISTANCE CHARTS article for ECM/PCM connector and terminal identification. Go to next step.
  2. Connect vacuum pump to disconnected fuel tank pressure control valve hose. Apply 3.5 kPa (14.0 in Aq) to purge hose and seal it. After 15 seconds, vacuum should still be 3.3 kPa (13.6 in Aq) or more. If system does not meet specified results, leak is present in EVAP system. Locate leak using soapy water or leak detector.
