Background: as my steering wheel cruise control buttons gradually fail, I use the brakes to drop out of cruise. A week ago I'd tap the brakes, then find that (sometimes) the accelerator was unresponsive and the SES was on (P0221 code). Get out of cruise or bang on the accelerator pedal, then it works. Well, not good, too many cases where a no-go accel could cause a crash (like up a steep hill from a stop with an idiot tailgater roach behind). Not using cruise control, everything works fine, no accelerator pedal problems.
So I find the part numbers for 2001-2003 7.3L (post 10/2000 build if I recall correctly):
Dorman aftermarket, poor reliability based on reviews: 699-203
APDTY aftermarket, poor reliability based on reviews: 700314
Standard Auto Parts, no bad reviews (lifetime A1AutoParts): APS103
OE original PN (discontinued, NOS is extremely expensive): 1C3Z-9F836-BA (or -C)
OE replacement seems to be:
-- bracket: 5C3Z-9C803-AA
-- pedal+sensor: EC3Z-9F836-A
-- just the sensor if that goes bad for the above: F4SZ-9B989-AA
Well, I'd rather get the Ford OE replacement for the original parts even though the cost is about 30-40 more than APS103 at this time. Forget Dorman or APDTY, too many "goes bads after 50-100 hours" type comments, loss of accel pedal is disturbing especially if the spouse is driving I'll never hear the end of using aftermarket parts. But, the connector has 10 pins, same shell appearance; the original connector is 10 pin sized but only has 5 pins, one row of the two rows.
So, if you have managed to get this far, will the EC3Z-9F836-A plug and go in a 2001 F350 built in 2001?
Do I need some kind of weird adapter connector like I had to get for the hydroboost, which Ford did not mention until I discovered that the connectors don't match kind of leaving me stranded in the land of partially complete repairs?
If I don't get an answer I'll buy the Ford parts and find out and post the results... I can't be the first one to go down this path.
And a story of the cruise control buttons. As the "stop cruise" button got less and less reliable, I'd tend to repeatedly press the button, and after a short time of ineffectiveness then mash the cruise button and press the brake pedal. One time, and one time only, this pattern of mashing the "stop cruise" and then hitting the brake at the same time resulted in the ECU trying to stay in cruise while I had the brakes applied!!!
Yes, in traffic, no crash. Somewhat hair raising to be pressing harder and harder on the brakes while the engine pushes harder and harder to maintain speed. Let up on the brakes and pressed again, the cruise dropped out, but I stopped using the cruise buttons to exit cruise after that... I have replacement buttons to install if I ever get around to it (new OE buttons, one expensive little box of buttons and wires, not questionable reliability aged buttons off eBay.).
