OFT VVT Intake/Exhaust readings
 

Hey guys,

I recently had new cam sprocket and ecu replacements due to a p0018 cel a few months back. So far no engine check lights and its been running normal. I decide to go and check how its holding up and noticed that my VVT intake readings are all over the place anywhere from 0 degrees to over 100 degrees. What can be causing these fluctuating readings? Is it going to harm the engine with these bad readings? My VVT exhaust angles look good. They were fixed after the repairs. Somehow now my intake is screwy.

Please help!

Thanks!

It possible its an oft channel logging issue, if the vvt cam sensor reading were that far off and erratic you would expect drivability isues and cel codes, maybe try logging same parameters on another car with same ecu calid as logging is specific ram addresses for each ecu calid

My A01E Calid ecu has a same issue with OFT.
I reported it to Shiv on March, but not fixed on August yet. :iono:

Were the VVT intake readings ok before the dealer did the repairs?

That sounds very strange, have you tried double checking with another OBD based bit of kit

Yes. After the cam sprockets didn't fix the issue they replaced the ECU. An updated 2015 ECU I think.

I don't have access to one at the moment. I'm leaning towards what steve99 and makinen. There's no cel or hesitation when driving. With my old ECU I never saw it behave in that way.

Mine does the same thing intake VVT is always erratic.
