Toyota Yaris: Fuel Pressure Sensor (for High Pressure) / 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. |
| *a | Component without harness connected (Fuel Pressure Sensor) | *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 | e2-3 (PR) - e2-2 (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. |

No special break-in is necessary, but a few precautions in the first 600
miles (1,000 km) may add to the performance, economy, and life of
the vehicle.
Do not race the engine.
Do not maintain one constant speed, either slow or fast, for a long
period of time.
Do not drive constantly at full-throttle or high engine rpm for
extended periods of time.
Avoid unnecessary hard stops.
Avoid full-throttle starts.
