code 332
I have a 92 f350 with a 5.8
My CEL is on and the code is 332 "insufficient EGR flow" The air pump and most of the lines are off the truck. I'm Guessing which is why the CEL came on.. Is there something I can unplug to make the light go off?
thanks!

Many (most) members don't get involved w/ engine's that have had component's eliminated, disconnected, bypassed. They're enough of a challenge without that further complication. Because virtually all aspects are integrated w/ the ECU as the headmaster.
It's impossible to restore normal function, no matter what advice is given, other than "Restore it to stock configuration!"
I assume your milage sucks, which is the opposite of why the smog pump & vac system component disabling are thought to be improving! Personally, I'd concentrate no putting Humpty Dumpty back together again, instead of disabling the system further.
When a sensor is disabled or consistently reporting out of range, the ECU eventually locks out that input & substitutes a fixed generic amount. A big hit to performance & driveability. A few of those & you'll end up in failsafe mode. If you think it's bad now, you haven't experienced "Failsafe mode"!

I didn't remove the parts I recently bought it that way. The truck is a service truck and weighs over 9000 pounds. It gets about 12.5 mpg. And lives in the mountains of northern Nevada. Is that mileage normal or would I see an increase with buying and reinstalling the parts? The is heavy and has 200k miles on it I thought it was getting good gas mileage.

Yes the CEL is recent. I think all that is missing is the air pump. Does that have anyhting to do with the EGR? The CEL is not on all the time it comes on after about ten min. of running and goes off and comes on about every 30min. of continued driving. I unplugged the EGR sensor and the truck wouldn't even start. Could I need a new sensor or EGR valve? Is there any way to test those two parts?

On your '92 code 332 indicates the EGR opening is not detected. This could be because the valve is truly not opening or the feedback to the computer (PCM) is faulty. Reference Ford Fuel injection for how the EVR, EGR and EVP sensor operate and how they can be checked.
3 digit error codes: Ford Fuel Injection Three-Digit Codes 224-525
EVP Sensor: Ford Fuel Injection EGR Valve Position sensor (EVP)
EVR: Ford Fuel Injection EGR Vacuum Regulator (EVR)
I have a '92 F350 4x4 w/5.8L engine and E4OD. I get 12 MPG running 65 MPH on the interstate. It goes down to 10 MPG at 70. I would say your 12.5 is about normal.
Code 332 has nothing to do with the air pump and associated components.

There is no way for this vintage truck to measure EGR flow. DTC 332 indicates the PCM is not sensing the opening of the EGR valve. Later models that use a DPFE sensor instead of the EVP on top of the EGR valve have this capability. Unless someone swapped in an EGR system and PCM that senses EGR flow code.
The closed EGR EVP signal should be between .2 and .67 VDC. The fully open position should be at or above 3.90 VDC.

With other codes specific to a EGR "closed" condition, like #328 & #334, voltage lower or higher than expected respectively for EGR closed valve position.

My EVTM Manual for 93-94 Ford trucks says almost exactly the same thing as Ryan's site for DTC 332:
Continuous Memory DTC 33/332 indicates that the EGR valve did not open with the engine stabilized and with EVR solenoid duty cycle present sometime during vehicle operation.
Possible cause:
-- Obstructed or cracked hose to EGR valve.
-- Damaged EGR valve.
-- Damaged EVR solenoid harness.
I am not trying to argue, but I do know vehicles equipped with DPFE use the same code when said sensor, that does measure flow, triggers a flow error. A vehicle with an EVP has no direct way to measure EGR flow.

I have a 95 300, since i bought it 2 months ago the CEL light is always on as soon as the engine raise a little temp. Starting from cold it takes a about 5 minutes, starting from hot in one minute. The trucks runs perfect and smooth I made the ECU test yesterday and gives me 332. But i made only the KOEO. Is it possibly this code with engine off or i made a bad count of the blinks?
