What U0682 means
Track E is usually the redundant second signal of the accelerator pedal, which the controller compares with track D before trusting any torque request. U0682 marks the loss of digital frames from that track. No manufacturer documents it publicly; GM and Ford wire pedal E analog, with Ford setting P2127/P2128 on voltage limits and P2138 when D and E disagree by more than 0.9 degrees. What matters to the driver is described in Ford's 2024 failure-mode table: with one track lost, demand is rate limited; with both gone, the engine ramps to a fixed high idle and ignores the pedal until the brake brings it back to idle. A digital pedal that sends both tracks in one SENT stream can therefore lose D and E together. CARB requires redundant pedal position data.
U0682 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyEasy, DIY possible
- Typical labor0.3 to 1.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U0682
- Check engine light and powertrain warning
- Delayed throttle response
- Fixed elevated idle with no pedal response if both tracks fail
Common causes of U0682
- Most likelySignal or reference wire of track E damaged
- PossibleWater or corrosion in the pedal connector
- PossiblePedal module electronics failed
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note U0682 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about U0682
What does U0682 mean?
U0682 means "Lost Communication With Throttle/Pedal Position Sensor/Switch E". Track E is usually the redundant second signal of the accelerator pedal, which the controller compares with track D before trusting any torque request. It is a generic code, so it means the same on every make.
Is it safe to drive with U0682?
Drive gently and only to a workshop. With U0682 the car can go into limp mode (reduced power) to protect itself.
Will U0682 fail an emissions test?
Yes, it can. U0682 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is U0682 to fix?
Difficulty: easy. A typical repair takes 0.3 to 1.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will U0682 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
