I have this car, and it had a blown head gasket, I have it repaired and the head milled, put it all back together and it idles fine, but when I drive it I get this code 2DA2, I have taken off the valve cover 2 times to check timing and all is good, replaced the solenoids on both cams, replaced the intake cam gear and retimed the damn thing and I still get this code, driving me crazy, ad help would be appreciated, thanks

 

I just finish timing and currently going through the same!

 

I may be way off but I thought 2DA2 is the Exhaust Cam. I was getting 2DA0 which was the Intake CamShaft position. When it went back in, it was definitely a real issue, they replaced the VANOS sprocket as well as the timing chain, was it the issue, I don't know but that was a few 1000 miles ago and its running fantastic since then. The chain definitely needed it at 90k miles.

 

I have the 2da2 code too timing is on everytime.. tool slides in..

replaced vanos solenoid, sprockets, exhaust cam seal, new timing chain.
new oil pump and solenoid.

car runs smoothly nothing strange..
Please advise

 

So when I was getting the same codes I actually did need the timing chain replaced but when the shop did replace the chain, they also found that one of the Vanos sprockets was not working properly. I am not certain how to test the operation of the sprocket. I want to say the sprocket was like $300 and the independent shop says they do see them go bad from time to time and look closely at them when they are doing the timing chain replacement.

 

We did the Chain as well as new sprockets
The thing is we take off the valve cover and the timing is on .
When we drive the car for a bit it does go to limp mode with that code on 2da2

The car runs and Idles good...
