P0016 on a 60k mile car

[jrhudson]

I have a built motor and actually replaced the two intake cam sprockets initially when the motor was first put together. Now at 1100 miles i got a P0018. I did the usually OCV and cam sensor swap with same code P0018. Now i'm trying to get techstream to work to verify if my cam sprocket is working in acceptable ranges and i'm a little confused on how to download it.

also would using a ecutek OBDII connector work with techstream?

When the CEL and slip lights come on, the rough idle or loss of power isn't apparent, at least to me, but i've been babying(>4000RPM) the car since i'm still in the break-in period.

In my car the loss of power was very subtle and really apparent when (legally) drag racing other similarly prepped cars. Totally driveable most of the time other than the code, but the loss of power was clear and verifiable.

After around 500 miles on a new small block I decided to push the engine a bit. The car threw a P0016 and then a few days later a P000b. I ended up taking the two exhaust OCVs out, cleaned them up and one of the plungers was sticking some. I used some compressed air and electronics cleaner, then swapped the OCV positions. I drove the piss out of it and my rough idle conditions disappeared and I haven't seen a code since.

Fingers crossed!

EDIT: Still good after 200ish miles of some hard driving. I'm thinking the plunger just got sticky after just sitting without oil for several months while I was working on the rebuild. That or some sealant got in there from the last rebuild/valve spring recall.

My brain is a little fried from 5+ hours of reading on this code so if the answer should be obvious please forgive me. I have a 2013 FRS m/t that I bought used with about 90k mi, about a year ago the engine decided to kamikaze itself driving home from work, I spent months trying to find a replacement. Found a pretty good deal on an engine/trans combo out of a 2014 FRS with about 74k mi on it. I swapped over to the replacement and started driving it, it threw the P0016 as well as P000A and P0011. After having a local mechanic take a look they said it seems fine mechanically(I doubt they checked values in ecu) I reset the codes and drove maybe 50mi over 3 days and my CEL and slip came on, but just P0016 comes up as pending/permanent/and stored.

This all leads to the question: Could blowing up my engine cause these codes to come up and now they are “burned in” on my ecu and need the “5k relearn” or is it more likely that it is caused by the new engine?

Hopefully this makes as much sense as it does in my head, again I’ve been reading about this for 5+ hours on a phone so my heads pretty fried.

EDIT- Not sure if anyone is still floating around this thread but to update I swapped the OCVs and checked the sensor. The sensor was definitely dirty so I cleaned that up and will be test driving tomorrow.

EDIT PT 2(P0016 boogaloo)- Cleaned sensor, cleared codes, drove for about 80mi so far and no more codes.

2013 FRS here

P0018 code

Tried swapping sensors left to right, code remained P0018. After reading all day on this the next plan is to swap in new cam gears and ECU.

Can someone confirm my shopping list?
