- 2007 VE SV6 MY08 Sedan
This post refers to my Holden VE SV6 Commodore (MY07) Sedan.
Over the past four months, my SV6 has experienced numerous shut downs, where the following warnings are illuminated:
• Check Engine
• Safety Mode Active
• Power Reduced
• Stability Ctrl Off
(In this order)
Twelve months ago, when the first shut down into “safe mode” occurred; the problem was identified as a stretched timing chain.
This was subsequently replaced (inc. new cogs etc).
Everything went well for about nine months.
Then new error-codes began to appear, which firstly indicated that the throttle body (sensor) needed to be replaced, followed shortly thereafter, by the throttle/pedal position sensor.
After travelling a single 620km highway drive (without any issues), the vehicle again shut down in “safe mode”!
The vehicle was inspected by my usual mechanic and a specialist technician. The decision was made to send the ECU to Melbourne for a more comprehensive diagnostic test.
Aside from detecting some corrosion on the zinc pins, the ECU was found to be in good condition. Errors could not be replicated ‘on the bench.’
The ECU was reinstalled into the vehicle and test driven. No faults could be replicated on the road drive.
The vehicle performed well for about two weeks. Then, one afternoon, I reversed out of my driveway and then engaged ‘Drive’ on the automatic transmission. As I applied pressure to the throttle pedal, the vehicle again entered “safe mode”!!
I am at a complete loss to understand what is causing this continual problem?
The vehicle is now back with my mechanic.
Does anyone have a confirmed diagnosis about what is happening?
Thanks in advance.
