FUEL RAIL PRESSURE SENSOR
1.
Reconnect harness connector disconnected.
2.
Start engine and warm it up to normal operating temperature.
3.
Check voltage between ECM terminals 48, 49 (Fuel rail pres-
sure sensor signal) and ground under the following conditions.
4.
If the voltage is out of specification, disconnect fuel rail pressure
sensor harness connector and connect it again. Then repeat
above check.
5.
If NG, replace fuel rail.
