What P0887 means
Some gearboxes draw their power through a relay, such as the transmission control relay in Chrysler's fuse box that feeds the solenoids. P0885 to P0887 cover the coil control of that relay, P0888 to P0892 its sense line, which reads back the switched output and compares it with the command. A dead relay leaves all solenoids without power, so the gearbox drops into its hydraulic emergency gear. P0887 means the coil control line sits high: a short to voltage or voltage present despite the command. FCA's 948TE nine-speed in the 2014–15 Cherokee, Chrysler 200 and Ram ProMaster City stored it with MIL, and three bulletins cured it with a gearbox module reflash, so an over-sensitive detection can cause it too.

Symptoms of P0887
- MIL on
- Shift problems or limp mode
Common causes of P0887
- Most likelyGearbox module software (FCA 948TE)
- PossibleControl wire shorted to voltage
- PossibleRelay faulty
- Less likelyGearbox 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 P0887 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 8 | Area: transmission. |
| 87 | The exact fault in that area. |
What to do next
- Note P0887 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 P0887
What does P0887 mean?
P0887 means "TCM Power Relay Control Circuit High". Some gearboxes draw their power through a relay, such as the transmission control relay in Chrysler's fuse box that feeds the solenoids. It is a generic code, so it means the same on every make.
Is it safe to drive with P0887?
Drive gently and only to a workshop. With P0887 the car can go into limp mode (reduced power) to protect itself.
Will P0887 fail an emissions test?
Yes, it can. P0887 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 P0887 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. This is a job for a workshop.
Will P0887 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
