Need a code master on this one
KOEO 111
Memory Code 332
Memory Code 617
KOER 311
KOER 538
KOER 632
My neighbor told me that i should be counting how many times the check engine light turns on during the tests so here is the blinking order
1,1,3,1,5,1,7,6,2,1,3,1,5,2,7,6,3,2
I dont know if that helps but i figured it never hurts to ask
heres what the site said
311 - Thermactor air system inoperative (right side)
332 - EGR valve opening not detected.
617 - 1 - 2 shift error (E4OD)
632 - Overdrive cancel switch not changing state (E4OD)
538 - Insufficient RPM change during KOER dynamic response test/ Operator error
(it also brought me to the throttle position page which said that all the following effect the TPS )
•Throttle Cable
•Throttle Body Cleanliness
•Vacuum leaks
•Air Filter
•Air Filter to Throttle Body Duct
•Engines general condition
•Harness and wire general condition
So now my question does any of these effect the others? I mean could i fix one thing out of all this and everything would work out better?
Does this sound more like a vaccum leak or something major?
I can use all the input on this one ... I'm leaning as i go but i also dont want to replace everything when it could be something minor....
(last spring my truck just wouldnt start and they told me that it was the fuel pump so $300 later it quit again and i found it was a $15 external ignition coil)
Code 332 - Insufficient EGR flow detected. Atop the EGR valve there is a sensor called the EVP (EGR Valve Position) sensor. It detects movement of the pintle iside the EGR valve. You can apply vacuum to the vacuum barb on the EGR valve and observe through the holes in the casting whether the valve is moving or not. It may just be dirty which requires some careful scrubbing and NO SOLVENTS. Otherwise, if the EGR valve is functioning and moving when vacuum is applied, the EVP sensor is suspect and the electrical connections to it should be checked first. (Computer needs to know the EGR valve position for emissions control).
Code 617 - 1-2 shift error. IF this code persists and you have noticed shift problems while driving, its going to be a shift servo inside the E4OD tha has failed. (Computer needs to control when the tranny is shifting).
Code 632 - OD cancel switch not changing state. During the KOER test, AFTER the initial recognition code is generated, the brake pedal must be applied, the OD switch must be turned off and then back on and finally the "goose" test must be performed. This code is generated when the person performing the KOER test fails to deactivate and reactivate the OD cancel switch at the end of the shift lever. It does NOT indicate a problem unless the switch WAS INDEED deactivated and reactivated and the code still came up. (Computer needs to know if the tranny is in OD or not).
Code 538 - Insufficient RPM change during dynamic response test. This is another code generated when the dynamic response or "goose" test as some refer to it is not performed during the KOER test. The KOER test requires that after a certain length of time the throttle be opened to bring the idle above 2000 rpm for a short period of time. If the dynamic response test is not performed or the rpm's do not peak ABOVE 2000 rpm's this code will be generated. (Computer needs to compare changes in sensor readings at different RPM's to determine system operation and efficiency).
The KOEO Code 111 is nothing to worry about it indicates the system is fine with the engine not running. The real concern here would be the Thermactor, EGR, and shift error codes. The other codes are usually a misperformed KOER test. If you have no shift problems with the truck it could be an anomoly caused by a combination of other codes. The Thermactor system is simple enough to trace and the EGR can be cleaned or replaced along with the EVP sensor. These two systems generate changes to fuel-air ratios and to oxygen levels in the exhaust which will affect other sensors and operations within the engine. If you want more specific repair and troubleshooting techniques, drop me a line.

The first is 213
Spout Circuit openIt is closed i check it, and when i pull the jumper off i can tell a difference in the timing change, i have read others who have replaced the wire and all that, and eventually through troubleshooting bought a new ECM and still having trouble, i will most likely ask my cousin if he has a spare ecm i can plug in and see before i leap and buy.
The second is 311
Thermactor air system/fault during engine run self testAccording to the posts to this blog 311 must be the right side and 312 is the left, which is helpful, but i still have no clue where to start locating a spot to begin my troubleshooting. But i will most likely jsut visually inspect all the ducting and such as GreyStreak 92 said.
The third, which is the second time for me, Is the EGR valve one, good old number 332, second time pulling the code for me, so i will tell the story. I went out and bought the EGR valve, and it did not fix it, and it was not cheap. That was the first time around. I was in the military for 3 years at that point, and wasnt using the truck, it was sitting at moms house then at cousins house. Well i said crap, did a lil research and realized i didnt do any troubleshooting at all, so i checked the lines, and low and behold the line from the egr valve was melted, and so was a A/C air line to switch from defrost to vent and what not, so they were replaced and the problem solved. Two years later here i am again. I went ahead and bought a pretty nice set of tools to check the integrity of my air lines, and they were not the cause. However i did replace the egr solenoid as it was making a odd hissing sound when i applied a load to it, and still it did not solve the problem. so here i am, i have not troubleshot the egr evp yet, and most likely will look up the voltage requirements for it now. Well thanks again.

Code 311 - as stated in my original post. However, I would suggest making certain that this code is cleared/corrected before assuming Code 332 is still a problem. One can trigger another if the system is off due to lack of air injection.
Code 332 - again, as described in the original post but do keep in mind that the EVP (EGR Valve Position) sensor must send a minimum voltage of 0.29 VDC back to the ECM when the valve is fully closed.
Check first for reference voltage at the BROWN/WHITE wire at the EVP sensor. With the key ON, the voltage should be approximately +5 VDC. If this voltage is below about +4.75 VDC inspect the wiring at the connection and back to PIN 26 of the ECM.
If the voltage at the BROWN/WHITE wire is good then check the voltage with the key ON and the engine OFF at the BROWN/LT. GREEN wire. The MINIMUM allowable voltage at this wire is 0.29 VDC with the EVP sensor connected and no vacuum to the EGR valve. If the voltage is below 0.29 VDC, replace the EVP sensor.
I missed that this was your first post... Welcome to FTE and the Big Bronco Forum. Here's hoping the information we have drummed up so far has been helpful. Keep us posted as to your progress.

Voltage came back good enough 12volts at the sensor.
However vaccum test came back iffie. Now it could be wrong but according to haynes manual, when 20Hg in of vac is applied to the evp sensor then the Ohms reading should be at about 100. I applied 10 Hg in of pressure and worked up to 20, and the Ohms reading went from about 300Hg in to 430 Hg in, is that normal or is haynes correct?
