Hello and thank you for using just answer!
Pull the front vavle cover on the engine here first, you likely have an issue with oil gel/sludge buildup here causing the vvt-i to malfunction.
No evidence of being of being cleaned out or flushed. Oil residue on V/C cover and gasket is brittle.
ok, oil residue is acceptable but sludge or hard formations would not be.
Do you have any history leading up to this concern? Such as maybe....the car had "x" service or repair done and now this is happening?
It can be that is why i am trying to gather more information here.
If the oil passages get clogged then the vvt-i takes a dump. On the other hand if the cam sensor readings get screwey then the vvt-i malfunctions, in other words if you have a cam reading issue then the vvt-i will malfunction based on those readings, it does not mean that you have a vvt-i issue here.
Is there any evidence that someone was recently inside the timing cover on this van? Perhaps a timingbelt job was recently done?
2007 at 90k miles was when the t-belt was done the vehicle has 118,000 miles now, so i don't think a cam/crank corralation is the problem. I must add that the customer says that when this stalling has happened before the vehile would not restart at times and would have the car towed back home, then at some point the car would start and run again.
ok, this sounds more like a wiring issue here then a mechanical issue then, thanks for your continued feedback here.
Have you done an ohm test of the wiring between the cam sensor and the ECM yet?
Have you looked closely at the entire harness to be sure a rodent has not chewed an wiring?
Let me check the wiring, and i'll get back to you.
best of luck, I'm online in the evenings if you need me.
