My experience with DTC P061b

paco_pony · 04-11-2007, 07:57 PM

Thought I would share my experience with this as some research on other forums yielded inconclusive answers. If this is common knowledge then please forgive me and ignore me (in that order, please).

I've been driving my new NA stroker around (no power adder but stroked guts, ported heads and cams) and all of a sudden it started going in to limp mode and throwing a check engine light. The scanner said P061b--the text around it is something like "torque calculation error". No other codes were thrown.

Some quick forum searches showed folks with similar problems-- a lot with blowers and a few with bolt on parts. But no conclusive answers about what the problem is and what the fix might be.

So I took the car in. One quick call to SCT from the shop owner and the problem was identified. An email with a patch to the tune was the solution. Loaded it up within 20 minutes and I'm good to go. No more trouble codes and car runs great.

The best I can tell is that the ECM measures engine load (ie, "torque") along with several other variables to figure out the right injector pulse width. If the ECM detects that the engine is under more torque or load than a stock engine should be (e.g., with a blower or aggressive bolt ons) then the ECM will throw this code and send the car into limp mode.

There is an easy fix for this in the tune--but not all tuners know about it. They just have to get the patch from the tuner co.

Anyway, hope this is somewhat worthwhile to someone.

Later...

Can you give me some more info about on code p061b? I have been having crazy issues with this code. I replaced my TPS on my 2007 stang and now I am getting this code, if you have any more info on this code please let me know.

The function that needs to be changed has the word "quizzer" in it.... I dont recall exactly what is says but as soon as I get my commando software loaded up I'll let you guys know. Any software can adjust this, its just in an obscure area. I have to fax in my user agreement so it will be a couple of days before I get the exact funtion name for you.

zuritausmc · 07-05-2010, 08:51 PM

Ah. So thats what the code means. I got this at the track twice in one day and called it a day but after that, I never got it again
