Fuel Charging and Controls The fuel charging and controls system consists of: fuel pressure regulator (9C968) fuel injection supply manifold (9F792) fuel injectors (9F593) fuel shut off valve solenoid (9D278) fuel pressure relief valve (9H321) injection pressure sensor engine fuel temperature sensor fuel charging wiring harness Component Location Fuel Pressure Regulator The fuel pressure regulator is located on the inside of the LH frame rail just forward of the transmission support crossmember. It is part of an assembly that includes the coalescer/filter. The fuel pressure regulator reduces the line pressure from tank pressure 20685 kPa (3000 psi) to line pressure 655 kPa (95 psi). Heating/Defrosting—Natural Gas Vehicle Fuel pressure regulator heating is provided by two 3/8-inch taps from the existing heater supply and return hoses on the RH rear of the engine. Two high-temperature 3/8-inch ID heater hoses (packaged with the front low-pressure fuel line) are used to connect the fuel pressure regulator to the tap points on the engine heater hoses. Refer to the Line — Low Pressure Fuel procedure in Section 310-01B for fuel pressure regulator heater hose replacement. Fuel Pressure Regulator Heater Hoses Fuel Injection Supply Manifold The fuel injection supply manifold delivers high-pressure fuel from the vehicle fuel supply line to the fuel injectors. The fuel injection supply manifold consists of the following: a tubular fuel rail eight fuel injector connectors a fuel pressure relief valve a fuel shut off valve solenoid mounting attachments which locate the fuel injection supply manifold and provide fuel injector retention. a fuel inlet connection which has a push-connect fitting an injection pressure sensor an engine fuel temperature sensor Fuel Injection Supply Manifold Fuel Injectors The natural gas fuel injectors are electro-mechanical devices that meter fuel delivered to the engine. The natural gas fuel injectors are mounted in the lower intake manifold (9424) and are positioned so that their tips direct fuel just ahead of the engine intake valves (6507). The natural gas fuel injector bodies consist of a solenoid and a needle and valve assembly. Natural gas fuel injectors can be identified by an aqua cap on the injector body. Fuel Shutoff Valve Solenoid The fuel shut off valve solenoid seals the upstream fuel pressure from entering the fuel injection supply manifold when the engine is not running. The fuel shut off valve solenoid is open only when it is activated by the solenoid valve (fuel pump) relay. Fuel Pressure Relief Valve The fuel pressure relief valve is located on the fuel injection supply manifold, and is used to relieve fuel system pressure from the fuel delivery system. Injection Pressure Sensor The injection pressure sensor is located on the fuel injection supply manifold, and is used to provide a signal to the powertrain control module (PCM) (12A650) that is proportional to pressure in the fuel injection supply manifold. Engine Fuel Temperature Sensor The engine fuel temperature sensor is located on the fuel injection supply manifold, and is used to provide a signal to the powertrain control module that indicates the temperature of the fuel in the fuel injection supply manifold. Fuel Charging Wiring The fuel charging wiring is a single harness that includes electrical connectors for the fuel injectors, ignition coils and various sensors, valves and senders that monitor all engine functions.

Removal WARNING: Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel-related components. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in personal injury. WARNING: Fuel in the fuel system remains under high pressure even when the engine is not running. Before working on or disconnecting any of the fuel lines or fuel system components, the fuel system pressure must be relieved. Failure to follow these instructions may result in personal injury. All engines 1. Disconnect the battery ground cable (14301). For additional information, refer toSection 414-01. 2. Relieve the fuel pressure. For additional information, refer toSection 310-00A. 3. Partially drain the cooling system. For additional information, refer toSection 303-03A or Section 303-03B. 4. Remove the power steering reservoir bracket. 1. Remove the bolts. 2. Position the power steering reservoir bracket out of the way. 5. Remove the accelerator control splash shield. 1. Remove the bolts. 2. Remove the accelerator control splash shield. 6. Disconnect the fuel pressure regulator valve vacuum hose. 7. CAUTION: After disconnecting, plug the fuel lines to prevent leakage. Disconnect the fuel lines. For additional information, refer toSection 310-00A. 8. Disconnect the eight ignition coil electrical connectors. 9. Disconnect the eight fuel injector electrical connectors. 4.6L engines 10. Remove the nut and disconnect the brake booster vacuum hose and bracket 5.4L engines 11. Remove the brake booster bracket and tube. 1. Remove the nut. 2. Release and move the two hose clamps. 3. Remove the brake booster tube. All engines 12. Remove the positive crankcase ventilation (PCV) hose. 5.4L engines 13. Disconnect the water heater inlet tube hose. 1.

1988 FUEL INJECTION Bosch AFC Toyota; Camry, Celica, Corolla, Cressida, Land Cruiser, MR2, Pickup, Supra, Van, 4Runner DESCRIPTION For specifications on Throttle Position Sensor (TPS), idle speed and mixture, and fuel pump output volume, see appropriate article in TUNE-UP PROCEDURES section. The Bosch AFC (L-Jetronic) fuel injection system is used on all models. However, variations may exist between model applications. This article covers the Bosch AFC system in general, with manufacturers’ differences noted under SPECIAL FEATURES. For computer control information, see the appropriate article in 1988 COMPUTERIZED ENGINE CONTROLS section. The Bosch Airflow Controlled (AFC) fuel injection system is an electronically controlled system operated by incoming airflow. Some vehicles are equipped with a potentiometer to measure incoming air flow, while other vehicles use a hot wire type airflow sensor.
