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. |

*b | Voltage Applied between Terminals | | |
| (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 E.F.I. vacuum sensor assembly detects the intake manifold pressure as a change in voltage. The ECM calculates the intake manifold pressure based on this voltage. The ECM calculates the EGR valve assembly and purge VSV (No. 1 vacuum switching valve assembly) opening amount accordin
