2008 Mazda 3 Engine Compartment Fuse Panel

The 2008 Mazda 3 vehicle’s electrical system is protected by fuses. If any lights, accessories, or controls don’t work, inspect the appropriate circuit protector. If a fuse has blown, the inside element will be melted. Note: If the same fuse blows again, avoid using that system and consult an Authorized
Mazda Dealer as soon as possible.

The following schematic diagram shows 2008 Mazda 3 (without turbocharger) Engine Compartment Fuse Panel, description, fuse rating and protected component.

2009 Nissan Sentra Refrigerant Flow Schematic Diagram

The 2009 Nissan Sentra refrigerant flows in the standard pattern, that is, through the compressor, the condenser with liquid tank, through the evaporator, and back to the compressor. The refrigerant evaporation through the evaporator coil is controlled by an externally equalized expansion valve, located inside the evaporator case. The refrigerant system is also protected by a pressure relief valve, located in the rear head of the compressor. When the refrigerant pressure in the system increases to an abnormal level [more than 3,600 kPa (36.7 kg/cm2, 522 psi)], the release port on the pressure relief valve automatically opens and releases refrigerant into the atmosphere.

The refrigerant system is protected against excessively high or low pressures by the refrigerant pressure sensor, located on the liquid tank. If the system pressure rises above or falls below the specifications, the refrigerant pressure sensor detects the pressure inside the refrigerant line and sends the voltage signal to the ECM.

1990 Toyota Supra MA70 Fuel System Circuit Diagram

Toyota Supra MA70 Fuel System Circuit
The following circuit diagram shows 1990 Toyota Supra MA70 Fuel System Circuit Diagram. The Fuel system is composed of 3 basic sub systems: Fuel, Air Induction and Electronic Control Systems. The Electronic Control System controls the following functions: Electronic Fuel Injection (EFI); Electronic Spark Advance (ESA); Idle Speed Control (ISC); Diagnosis (detects any malfunctions or abnormalities in the sensor network and lights the "CHECK ENGINE" warning light on the instrument panel); and Fail-safe Function. (click image to enlarge).

The ECU receives signals from various sensors indicating changing engine operating conditions such as: Exhaust oxygen content, Intake air volume, Intake air temperature, Coolant temperature, Engine rpm, Acceleration / deceleration etc. These signals are utilized by the ECU to determine the injection duration necessary for an optimum air-fuel ratio.

The ECU is programmed with data for optimum ignition timing under any and all operating conditions. Using data provided by sensors which monitor various engine functions (rpm, AIC signal, coolant temperature, etc.), the microcomputer (ECU) triggers the spark at precisely the right instant. (See IG section).

The ECU is programmed with target engine speed values to respond to different engine conditions (coolant temperature, air conditioner on/off, etc.). Sensors transmit signals to the ECU which control the flow of air through the by-pass of the throttle valve and adjust idle speed to the target value.

2000 Nissan Pathfinder Heater Circuit Diagram and Air Conditioner Wiring Diagram

Nissan Pathfinder Heater Air Conditioner Circuit Wiring
The 2000 Nissan Pathfinder Heater and Air Conditioner System flows in the standard pattern, that is, through the compressor, the condenser, the liquid tank, through the evaporator, and back to the compressor. The refrigerant evaporation through the evaporator coil is controlled by an externally equalized expansion valve, located inside the evaporator case. Under normal operating conditions, when the A/C is switched ON, the compressor runs continuously, and the evaporator pressure, and therefore temperature, is controlled by the V-6 variable displacement compressor to prevent freeze up.

The refrigerant system is protected against excessively high or low pressures by the dual-pressure switch, located on the liquid tank. If the system pressure rises above, or falls below the specifications, the dual-pressure switch opens to interrupt the compressor operation. The refrigerant system is also protected by a pressure relief valve, located in the rear head of the compressor. When the pressure of refrigerant in the system increases to an abnormal level [more than 3,727 kPa (38 kg/cm2, 540 psi)], the release port on the pressure relief valve automatically opens and releases refrigerant into the atmosphere.
