No, the leak could be on the VSV actuator.
A slightly misaligned seal in the VSV actuator can couse a leak out of the drain port.
By performing a actuator test or starting the engine the seals realign most of the time.
The message "... SIGNAL OUT OF RANGE" normally indicates that the EEC detects a signal which is not in the valid range.
This has nothing to do with a leak.
More important than the message is the fault number. It is shorter, gives you more information and the chance of misspelling is lower.
The message "VSV ACTUATOR SIGNAL OUT OF RANGE" does not exist!
