Diagnosis & Repair
Using Toyota hand-held tester or scan tool, read FREEZE FRAME data. Freeze frame data records engine conditions when malfunction is detected. When the ENGINE RUN TIME in the freeze frame data is less than 200 seconds, carefully check the vapor pressure sensor.
For EVAP system component locations, see Fig. 86 . For EVAP emission control system wiring diagram, see Fig. 87 . For diagnosis and repair procedure using Toyota hand-held tester, see Fig. 88 -Fig. 108 . For diagnosis and repair procedure using OBD II scan tool, see Fig. 109 -Fig. 116 .
When access to, or replacement of ECM is necessary, Engine Control Module (ECM) is located behind glove box. See Fig. 8 . For ECM connector terminal view, see Fig. 10 . For vacuum or EVAP hose routing, see VACUUM DIAGRAMS article. For testing of systems or components, see BASIC DIAGNOSTIC PROCEDURES - 4-CYLINDER article or SYSTEM & COMPONENT TESTING - 4-CYLINDER article. For adjustments, see ON-VEHICLE ADJUSTMENTS - 4-CYLINDER article. For removal and installation of components, see REMOVAL, OVERHAUL & INSTALLATION - 4-CYLINDER article.
