Have Ford Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner past midnight.
061B indicates the MAF sensor is likely dirty or bad.
1336 mean the computer is not getting a comparing signal from the CMP and CKP sensors.
Do you have a scan tool that can show the reading of the MAF sensor and monitor the CMP and CKP sensors?
Do you want the Ford diag steps for these codes?
This is my 1st answer of what can be many. You the website and myself expect you to have a ~~~5 STAR EXCELLENT~~~ experience with my help. At the top of your screen is the rating box that you only get to use once. Please make sure to complete the mandatory rating when ready or reply and say "I am pleased with my answer". Not rating or rating 1-2 stars does not benefit you nor me in any way.
Let me know the results you get from monitoring the MAF and CMP and CKP. You will need to freeze frame the CMP and CKP at various rpms to see if either drops out.
I give that a very small percentage of being the case. If the chain were slack you would hear it while running.
I would expect noise from the chain if it were slack.
Can you give me all the readings your tool will give for the MAF key on engine off and then again at hot idle?
The numbers from the MAF are good so now its time to address the CMP/CKP code since they can cause the 061B code.
Did you monitor those sensors in freeze frame data like I mentioned prior to see if either drops out?
Can you do these tests? https://dl.dropboxusercontent.com/u/90220402/1336.pdf
Below is a file showing the readings from all sensors.
TP1 and 2 do not read the same since they measure different segments of throttle. 1 measures the first half and the other measures the 2nd half.
Hello again Chris here,
