3.
Measure resistance between the terminals 1 and 2 of the rail pressure control valve connector.
Rail pressure control valve(PCV) is installed in common rail.
If controls common rail pressure fast as regulating returning quantity if fuel which is delivered to common rail when fast rise of rail pressure is required like the moment of turning engine ON or when fast relief of pressure is required like at the point of receleration.
Temperature ℃(℉) | Resistance (Ω) |
20(68) | 3.42 ~ 3.78 |
Turn the ignition key off.
Disconnect the rail pressure control valve connector.
Measure resistance between the terminals 1 and 2 of the rail pressure control valve connector.
Refering to "SPECIFICATION", check that the resistance is within specification.
