How to test VVT actuator function in 207 1.4 VTI?

Unread post by ---tapsa--- »

Ladies and Gentlemen - thanks about letting me into this great group 🙂
My daughter have a Peugeot 207 1.4 VTI and yesterday it was running okay but today not even starting. Battery, spark, fuel pump pressure etc checked and those are okay but how to check functioning of actuators 1, 2 and 3?
What kind of voltage shall present on those, when starting the engine?
I have Delphi clone and there possibility to test these actuators, number 3 is doing something during test but both 1 and 2 are doing nothing. Resistance of number 1 is 7 ohm. During testing the voltage is 3.3 V and varying between 3.2 V … 3.4 V, nothing more.I

... and Delphi did not find any fault codes in any ECU

Update: VVT actuators are fine and car is running now:
- changed 3 month old battery to 2 years old one and engine run
- changed battery back to few months old one and still running fine
Case closed
