Engine codes

85reds10 · 05-02-2007, 10:28 PM

I ran the paper clip trick diagnostic and it gave me codes 33, 35 and 45.
on code 35 which one of the options would apply to me?? I Have TBI so would it be the IAC fault, ISC fault, or Baro sensor?? And what does IAC and ISC stand for. What does the MAP sensor look like??
Any help would be greatly appreciated

What year and engine and mileage?
Make sure vacuum line is good and getting good vacuum to map sensor.
Map sensor is a little black box about 1 in wide by 3 in long and 1/2 thick with one vacuum line and about 3 w1res going into it.
You can drop by your local parts place and they will show you one.
Clear codes and see what one comes back first.

Well i did check the MAP sensor and it turned out to be good and it still runs like s***. All i have left is to change the IAC and see if thats the problem.

How or what did you check on it?
Good vacuum to it?
What was the voltage reading on map? Engine off and engine running?
