Toyota Corolla Cross: Inspection
INSPECTION
PROCEDURE
1. INSPECT FUEL PRESSURE SENSOR
(a) Check the fuel pressure sensor output voltage.
| (1) Apply 5 V between terminals 1 (VC) and 2 (E2).
NOTICE:
- 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 more than 6 V to terminals 1 (VC) or 2 (E2).
HINT: If a stable power supply is not available, connect 4 nickel-metal hydride batteries (1.2 V each) or equivalent in series. |

| (2) Measure the voltage according to the value(s) in the table below.
Standard Voltage: |
Tester Connection | Condition |
Specified Condition | |
3 (PR) - 2 (E2) | Pressure not applied to fuel pressure sensor |
Approximately 0.4 to 0.6 V* | *: The output voltage changes depending on the voltage applied to the terminals.
If the result is not as specified, replace the fuel pressure sensor. |

DESCRIPTION The engine stop and start ECU determines changes in the brake booster assembly pressure based on the voltage signal received from the vacuum sensor assembly in the brake booster assembly.
If the output value of the vacuum sensor assembly remains the same even though the brake booster a
