Ever since I purched a superchips code reader and installed the performance tow program, I have constantly had an error code 0236 MAP Turbo boost sensor A circuit come up. When I clear them it will stay away for a little while and then reapear within 100 miles or so. Truck runs great so I've ignored it (replaced the map sensor and checked the hoses-didn't help). Anyone have any suggestions or should I keep on ignoring it?

97 F250, Superchips perf-tow, 137,000

 

From Steve Baz site:

0236* MAP Turbo boost sensor A ckt performance. Uses Inferred MAP signal. Restricted inlet/exhaust/supply hose, missing hose.

Also got this from another site:

0236 = Detected high boost signal at low idle. (Restricted MAP line)

Do you still have the catalitic converter? Possibly it's getting plugged. This is also from Steve Baz site:

Gutting The Cat
Cat Delete Pipe -- Ford part number F4TZ-5A212-V

Best way to remove the cat is to loosen the clams front and rear. With a marker mark the front and align the mark at the very bottom to help you get it back on in the right direction and bottom facing straight down. NOTICE THE LITTLE TIT AND NOTCH AT THE BACK OF THE CONVERTER, THAT MUST BE LINED UP TO RE-INSTALL. Unhinge both muffler hangers behind (2) of them go to the drivers side of the truck and pull the cat in that direction and with a dead blow hammer or a heavy hammer OR with a piece of 2 x 4 hit the cat forward until it releases. Then wiggle the front section loose.

Now is the fun part. With a steel breaker bar or a pipe or anything that is longer than the length of the cat start beating the honey comb up and keep dumping it out of the side your hitting. do this until it is all out. Hint beat the crap out of it is not as simple as it seems. Make sure it is all clear before removing because you do not want any rattles.

Installing the cat back by banging the cat fully into the front using the mark to align the cat right and the arrow forward. Hint: Make sure the cat it seated all the way forward before re-claming. Then make sure you align the back to the tit and notch before you start banging the back in place. Make sure the tit is all the way seated before clamping and set the hangers back before tightening the clamp. Finish tightening and then go back and tighten again because it must be very tight. Check the exhaust hangers and make sure they are on properly. Your done...... Great job you just gutted the cat.

 

HI could also be the programer I got one last week and it didnt work properly traded it
in for a new one and it works fine is this code present when you use the tow safe program?

 

Thanks for the info guys. It would probibly be easier to just replace the cat with a piece of pipe than pound it apart. That's what I will probibly try first. It seems from reading some of the posts that alot of you like to remove the cat and muffler....
