Start off by saying its a 1994 300 e4od two wheel drive. fuel mileage isn't great but I think it has to do with my driving and engine light went on for about 15 seconds the other day then went out and hasn't been back on yet. Scanned codes with the engine warm and this is what I got.

Koeo was three slow flashes a pause then three more so I'm guessing 33, Egr didn't open or respond?

Continuous, these were quick flashes and they were 33, 23 and 32 so egr related and a throttle sensor?

The engine on test had three flashes meaning it's the six cylinder, I hit the brake then no lights and had a high idle.

I believe I did everything right but I'm lost with what went wrong with the engine on test and what the Egr codes and throttle sensor meant. Any help on this would be great thanks.

 

Three digit codes on your '94. You got 111, system pass.

 

So I guess the continuous 332 means pass too then?

 

No. You didn't say 332 you said something totally wrong. I'm not near my book, but it's an EGR code.

 

Sorry I thought they were two digit codes, if there three, koeo would be 111 then 111 again, continuous would be 332 and 332 again. Does this make sense or am I out to lunch?

 

From what you wrote, 332 is correct.

 

Okay thanks, a google search came up with these as possible causes:

-- Obstructed or cracked hose to EGR valve.
-- Damaged EGR valve.
-- Damaged EVR solenoid harness.

I'll go see how the hoses are looking
