If he isn't why he didn't change non-return valve first.
Fault Codes 6/78390 (Malfunction In Throttle Valve Control)
2) Check for leaks in vacuum circuit by starting engine.
Disconnect hose between non-return valve and intake manifold. If this
causes arm on throttle housing to retract, there is a system leak. To
pinpoint leak, pinch hoses, one at a time, from non-return valve via
safety valve to throttle housing. Replace any components that may be
causing leak.
