- INSPECT FUEL PRESSURE SENSOR
- Check the fuel pressure sensor output voltage.
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Condition Specified Condition 3 (VOUT1) - 2 (GND) Apply 5 V between terminals 4 (VCC) and 2 (GND) Approximately 0.5 V TEXT IN ILLUSTRATION*a Component without harness connected
(Fuel Pressure Sensor)NOTE:- Be careful when connecting the leads, as the fuel pressure sensor may be damaged if the leads are connected to the wrong terminals.
- Do not apply a voltage of 6 V or more to the terminals 4 (VCC) and 2 (GND).
HINT:
If a stable power supply is not available, use 4 1.2 V nickel-metal hydride batteries, etc.
If the resistance is not as specified, replace the fuel pressure sensor.
