WARNING: This page is about a different car, the 2002 Suzuki Esteem. However, it is still accessible from the selected car via links, so may be relevant.
  1. If engine system check has been performed, go to next step. If engine system check has not been performed, go to A4: ENGINE SYSTEM CHECK  under SYSTEM TESTS.
  2. Turn ignition off. Disconnect EVAP-CPV 2-pin harness connector. EVAP-CPV is located on end of intake manifold. Measure voltage between ground and EVAP-CPV harness connector terminal No. 2 (Red/Black wire). Voltage should be 10-14 volts. If voltage is as specified, leave harness connector disconnected and go to next step. If voltage is not as specified, check for and repair open or short to ground in Red/Black wire between EVAP-CPV, main relay and ECM. See WIRING DIAGRAMS article. If problem is found, repair as necessary. After repair, repeat DTC CONFIRMATION TEST  .
  3. Check EVAP-CPV circuit operation. See EVAP CANISTER PURGE VALVE under FUEL EVAPORATION in SYSTEM & COMPONENT TESTING article. If problem is found, replace EVAP-CPV. If no problem is found, substitute a known good ECM, and repeat DTC CONFIRMATION TEST  . If DTC does not reset, testing is complete.
