The composite vehicle type 3 powertrain control system is based on designs common to many vehicle manufacturers, but is not identical to any actual production vehicle.  \nGENERAL DESCRIPTION  \nThis generic four cycle, V6 engine has four overhead chain-driven camshafts, 24 valves, distributorless ignition, and a mass airflow-type closed-loop sequential multiport fuel injection system. The Engine Control Module (ECM) receives input from sensors, calculates ignition and fuel requirements, and controls engine actuators to provide the desired driveability, fuel economy, and emissions control. The ECM also controls the vehicle’s charging system. The powertrain control system has OBD II-compatible sensors and diagnostic capabilities. The ECM receives power from the battery and ignition switch and provides a regulated 5 volt supply for most of the engine sensors. The engine is equipped with a single exhaust system and a three-way catalytic converter, without any secondary air injection. Engine control features include variable valve timing, electronic throttle actuator control (TAC), a data communications bus , a vehicle anti-theft immobilizer system, and onboard refueling vapor recovery (ORVR) EVAP components. The control system software and OBD II diagnostic procedures stored in the ECM can be updated using factory supplied calibration files and PC-based interface software, along with a reprogramming device or scan tool that connects the PC to the vehicle’s data link connector (DLC) .  \nAUTOMATIC TRANSMISSION  \n● Four-speed automatic overdrive transaxle, with shifting controlled by a transmission control module (TCM) . The TCM communicates with the ECM and other modules through the data bus.  \n● The TCM provides its own regulated 5 volt supply, performs all OBD II transaxle diagnostic routines, and stores transaxle diagnostic trouble codes (DTCs) . The control system software and OBD II diagnostic procedures stored in the TCM can be updated in the same way as the ECM.  \n● Failures that result in a pending or confirmed DTC related to any of the following components will cause the TCM to default to fail-safe mode: range switch, shift solenoids, turbine shaft speed sensor, and the vehicle speed sensor. The TCM will also default to fail-safe mode if it is unable to communicate with the ECM.  \n● When in fail-safe mode, maximum line pressure will be commanded, the transmission will default to 2nd gear, and the torque converter clutch will be disabled.  \nFUEL SYSTEM  \n● Sequential Multiport Fuel Injection (SFI)  \n● Returnless Fuel Supply with electric fuel pump mounted inside the fuel tank  \n● Fuel pressure is regulated to a constant 50 psi (345 kPa) by a mechanical regulator in the fuel tank. Minimum acceptable fuel pressure is 45 psi (310 kPa) . The fuel system should maintain a minimum of 45 psi (310 kPa) for two minutes after the engine is turned off.  \nIGNITION SYSTEM  \n● Distributorless Ignition (EI) with six ignition coils (coil-on-plug)  \n● Firing Order: 1-2-3-4-5-6  \n● Cylinders 1, 3, and 5 are on Bank 1, Cylinders 2, 4, and 6 are on Bank 2  \n● Ignition timing is not adjustable  \n● Timing is determined by the ECM using the crankshaft position (CKP) sensor signal  \n● The ignition coil drivers are integrated into the ECM  \nVARIABLE VALVE TIMING  \n● Intake camshaft timing is continuously variable using a hydraulic actuator attached to the end of each intake camshaft. Engine oil flow to each hydraulic actuator is controlled by a camshaft position actuator control solenoid. Exhaust camshaft timing is fixed.  \n● A single timing chain drives both exhaust camshafts and both intake camshaft hydraulic actuators. While valve overlap is variable, valve lift and duration are fixed.  \n● Cam timing is determined by the ECM usin","cbCairFBpVqx3KFA","https://ap.wps.com/l/cbCairFBpVqx3KFA","pdf",5813163,24,"English","# General Description\n## Automatic Transmission\n## Fuel System\n## Ignition System\n## Variable Valve Timing\n## Electronic Throttle Control","[{\"question\":\"What engine features are covered in this reference booklet?\",\"answer\":\"It describes a generic four-cycle V6 with four chain-driven camshafts, 24 valves, distributorless ignition, and a mass airflow-type closed-loop sequential multiport fuel injection system.\"},{\"question\":\"How do ECM and TCM interact for diagnostics and control?\",\"answer\":\"The ECM and TCM communicate through a data communications bus, with the TCM performing OBD II transaxle diagnostic routines and storing transaxle DTCs.\"},{\"question\":\"What happens when the electronic throttle control system detects sensor failures?\",\"answer\":\"If one APP/TP sensor fails, the ECM limits maximum throttle opening to 35% and turns on the MIL; if two or more sensors fail, it disables electronic throttle control and defaults to limp-in mode with a 15% throttle opening.\"}]","ADVANCED ENGINE PERFORMANCE SPECIALIST TEST - COMPOSITE VEHICLE TYPE 3 REFERENCE BOOKLET | PDF",1790930363]
