I have a 2007 Ford Five Hundred SEL FWD w/ 6 speed trans. 235,000 miles. I keep it well maintained with only Motorcraft Parts (if possible).
Driving Fine All Day, parked, came out of store- starts fine, But can’t make it across parking lot. Stumbles & red PATS light comes on & dies. 6 listed fault codes: U-0300, P-060A, P-1000, P-0642, P-2105, P-2107. Took to FORD dealer I bought it from new after I couldn’t diagnose. I’ve tried NEW Battery, Throttle Body, & Throttle Pedal. They had it a month. They thought since motor mounts bad & motor shifting, Might be a break in harness. They replaced all motor & Trans. mounts. They said “Could not duplicate codes with moving harness (NLA)”. Next, They said ” PCM must be bad (NLA)”. I got a rebuilt PCM from All Computer Resources in FL. Comes with keys programmed to my VIN, Just cut new keys. Plug & Play; Lifetime Guarantee. Took Another month & They installed it. They said ” Alternator was erratic”, So It was replaced. I was told car was fixed. Paid thousands & made it just blocks. Ck. Light on, Stumbles & Dies if rpm’s below 2,000. Keep speed up, It runs for many miles. Drop speed to stop, Stumbles, Bucks, & Pats light comes on & DIES. Absolutely the exact same problem I filled out the work order with. Got the car home. Have been arguing with FORD Dealer for 2 months. They won’t take it back in under a guarantee. Managers won’t talk to me OR return calls. Won’t refund anything. I checked and all of the original codes listed above are now in the New PCM too. I’m don’t know where to turn next. I’m diagnosing on my own, Bought a BOSCH 1350 scanner & know how to use a multi-meter. Got the FORD wiring diagram manual.
PLEASE, If any ideas (other than trash the vehicle), I sure could use help as to what to try next. I’ve thrown thousands to “Professionals”, Only to be back to the beginning on my own. I’m a Yamaha motorcycle mechanic of 52 years, But I’m a bit over my head here. I don’t have a scope OR Programming equipment. Any & All advice would be appreciated.
UPDATE 9-11-2024 :
This is a E-Mail sent to All Computer Resources in FL from me. It is a good read.
“Hi Support,
I gave up on help from “Professionals” & Diagnosed the multiple fault codes in the computer Myself. It turned out to be a defective #4 Ignition Coil. Of the SEVEN CODES listed after the New PCM was installed by the Dealer & Those are the same codes it had in it when brought into the FORD Dealer I paid Sunset Ford for their time & took the car home to diagnose myself. There were No codes set for misfires, But That was what was setting the varied codes that didn’t make sense & when checked with a meter, Were shown to be not in error. The coil was sending signals back to the PCM & setting errors that were NOT AT FAULT. Replacing the # 4 Ignition Coil ONLY & Clearing all codes (Other than P-1000), Turned the car from a Shuddering & Dying mess, Back to a perfectly running vehicle with no codes at all. I’ve driven it close to 100 miles since the fix & No issues at all.
I have received a Refund Check from SUNSET FORD for PCM diagnose Error in the sum of $ 760.00 today & placed it back in the bank. I really didn’t need the computer from you that was requested by SUNSET FORD, BUT I’m NOT looking for any kind of a Return OR Refund from your company as the car has your PCM in it & is running great. I don’t want to start changing a car that is PERFECT NOW.
Thank You for your product & I hope that I will never need that lifetime warranty you included. Since this was such a Unexplained Problem of non-common sense, You might want to remember this strange Multiple error code issue, Should it come up in the future.
Sincerely,
Robert “
