U019E code meaning
Lost Communication With Transmission Range Control Module
What U019E means
U019E covers the transmission range control module, in shift-by-wire designs the electronics that engage park, reverse, neutral or drive on behalf of the driver's selector. Ford lists U019E in its 2014 OBD code list without the MIL marker it gives emissions-related codes. No further public manufacturer source was found; NHTSA's bulletin index is silent on it as well. The neighbouring code U0103 belongs to the selector itself, gear shift control module A, which reports the driver's request to this unit. Shift-by-wire needs a redundant data path, so losing the range module typically means a refused gear change, a prompt to secure the car or an automatic move to park. U049F is invalid data, U01BA the park lock module.
U019E at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyHard
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U019E
- Gear selection refused or vehicle stays in park
- Shift system warning in the cluster
- Transmission engages park on its own when stopping
Common causes of U019E
- Most likelyRange control module without power, ground or wake-up
- PossibleBus connector at the transmission corroded or loose
- PossibleLow battery voltage during cranking or parking
- Less likelyTransmission range control module faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U019E means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 9E | The exact fault in that area. |
What to do next
- Note U019E 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 U019E
What does U019E mean?
U019E means "Lost Communication With Transmission Range Control Module". U019E covers the transmission range control module, in shift-by-wire designs the electronics that engage park, reverse, neutral or drive on behalf of the driver's selector. It is a generic code, so it means the same on every make.
Is it safe to drive with U019E?
Drive gently and only to a workshop. With U019E the car can go into limp mode (reduced power) to protect itself.
Will U019E fail an emissions test?
U019E is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is U019E to fix?
Difficulty: hard. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will U019E clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
