2AZ-FE ENGINE CONTROL SYSTEM – SFI SYSTEM ES–1 ES SFI SYSTEM PRECAUTION NOTICE: • Perform RESET MEMORY (AT initialization) when replacing the automatic transmission assembly, engine assembly or ECM (See page AX-16). • Perform REGISTRATION (VIN registration) when replacing the ECM (See page ES-16). HINT: Initialization cannot be completed by removing the battery. ES–2 2AZ-FE ENGINE CONTROL SYSTEM – SFI SYSTEM ES DEFINITION OF TERMS Terms Definition Monitor Description Description of what ECM monitors and how detects malfunctions (monitoring purpose and details). Related DTCs Group of diagnostic trouble codes that are output by ECM based on the same malfunction detection logic. Typical Enabling Condition Preconditions that allow ECM to detect malfunctions. With all preconditions satisfied, ECM sets DTC when monitored value(s) exceeds malfunction threshold(s). Sequence of Operation Order of monitor priority, applied if multiple sensors and components involved in single malfunction detection process. Each sensor and component monitored in turn, when previous detection operation is completed. Required Sensor/Components Sensors and components used by ECM to detect each malfunction. Frequency of Operation Number of times ECM checks for each malfunction during each driving cycle. "Once per driving cycle" means ECM only performs checks for that malfunction once in single driving cycle. "Continuous" means ECM performs checks for that malfunction whenever enabling conditions are met. Duration Minimum time for which ECM must detect continuous deviation in monitored value(s) in order to set DTC. Timing begins when Typical Enabling Conditions are met. Malfunction Thresholds Value, beyond which, ECM determines malfunctions exist and sets DTCs. MIL Operation Timing of MIL illumination after malfunction is detected. "Immediate" means ECM illuminates MIL as soon as malfunction is detected. "2 driving cycle" means ECM illuminates MIL if the same malfunction is detected second time in the next sequential driving cycle. 2AZ-FE ENGINE CONTROL SYSTEM – SFI SYSTEM ES–3 ES PARTS LOCATION PZEV: PURGE VSV CANISTER CANISTER PUMP MODULE FUEL PUMP ECM ENGINE ROOM R/B AND ENGINE ROOM J/B EFI NO. 3 FUSE EFI NO. 2 FUSE EFI NO. 1 FUSE (ENGINE ROOM J/B) - - EFI MAIN FUSE CIRCUIT OPENING RELAY MASS AIR FLOW METER EFI RELAY INTEGRATION RELAY A137360E01 ES–4 2AZ-FE ENGINE CONTROL SYSTEM – SFI SYSTEM ES EXCEPT PZEV: PURGE VSV CANISTER FUEL PUMP ECM ENGINE ROOM R/B AND ENGINE ROOM J/B EFI NO. 3 FUSE EFI NO. 2 FUSE EFI NO. 1 FUSE (ENGINE ROOM J/B) - - EFI MAIN FUSE CANISTER PUMP MODULE CIRCUIT OPENING RELAY MASS AIR FLOW METER EFI RELAY INTEGRATION RELAY A137361E01 2AZ-FE ENGINE CONTROL SYSTEM – SFI SYSTEM ES–5 ES PZEV: FUEL INJECTOR IGNITION COIL HEATED OXYGEN SENSOR PARK/NEUTRAL POSITION SW INTAKE MANIFOLD RUNNER VALVE (IMRV) CAMSHAFT POSITION SENSOR CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY CRANKSHAFT POSITION SENSOR ENGINE COOLANT TEMPERATURE SENSOR KNOCK SENSOR THROTTLE BODY AIR-FUEL RATIO SENSOR A135059E01 ES–6 2AZ-FE ENGINE CONTROL SYSTEM – SFI SYSTEM ES EXCEPT PZEV: FUEL INJECTOR IGNITION COIL AIR-FUEL RATIO SENSOR HEATED OXYGEN SENSOR PARK/NEUTRAL POSITION SW CAMSHAFT POSITION SENSOR CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY CRANKSHAFT POSITION SENSOR ENGINE COOLANT TEMPERATURE SENSOR KNOCK SENSOR THROTTLE BODY A132270E01 2AZ-FE ENGINE CONTROL SYSTEM – SFI SYSTEM ES–7 ES INSTRUMENT PANEL J/B COMBINATION METER CLUTCH START SWITCH IGNITION SWITCH STOP LIGHT SW DLC3 - IGN FUSE - STOP FUSE ACCELERATOR PEDAL ROD A132271E01 ES–8 2AZ-FE ENGINE CONTROL SYSTEM – SFI SYSTEM ES SYSTEM DIAGRAM M M EFI MAIN EFI No. 1 EFI No. 2 EFI No. 3 Purge VSV IGN IG SW ST/AM2 ALT AM1 AM1 AM2 IG1 IG2 C/OPN To C/OPN Combination Meter GAUGE No. 2 FL MAIN STOP Stop Light SW To IGN To IGN Battery To Battery STP ST1- E1 E01 E04 E03 IAC+*1 IAC-*1 W MIL ETCS IMRV (Intake Manifold Runner Valve) Motor +BM ALT Generator DLC3 TC FC TACH Fuel Pump ECM BATT +B +B2 MREL PRG IGSW *1: PZEV Only EFI To Park/Neutral Position SW A132314E01 2AZ-FE ENGINE CONTROL SYSTEM – SFI SYSTEM ES–9 ES Mass Air Flow Meter Engine Coolant Temperature Sensor Air-fuel Ratio Sensor Heated Oxygen Sensor Throttle Actuator No. 1 Fuel Injector No. 3 Fuel Injector No. 2 Fuel Injector No. 4 Fuel Injector Knock Sensor ECM GE01 #10 #20 #30 #40 E02 ME01 E2G VG THA ETHA THW ETHW To INJ HA1A A1A+ A1A- HT1B OX1B EX1B KNK1 EKNK M+ M- A132315E01 ES–10 2AZ-FE ENGINE CONTROL SYSTEM – SFI SYSTEM ES Crankshaft Position Sensor Camshaft Position Sensor Throttle Position Sensor IMRV Position Sensor Camshaft Timing Oil Control Valve No. 1 Ignition Coil No. 2 Ignition Coil No. 3 Ignition Coil No. 4 Ignition Coil Park/Neutral Position SW or Clutch Start SW To Starter To IG SW To IG SW ST To INJ *1: PZEV Only *2: Automatic Transaxle Only ECM OC1+ OC1- IGT1 IGT2 IGT3 IGT4 IGF1 NSW*2 STA NE+ NE- G2+ G2- VCTA VTA1 VTA2 ETA VCIA*1 IACA*1 EIA*1 A132316E01 [...]...
