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. |
