What P0892 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. P0892 reports a sense signal that drops out now and then, from a loose contact in relay, socket or wiring. Brief supply interruptions can reboot the module (compare P0884) and cause shift shocks. No maker publishes a strategy.

Symptoms of P0892
- Sporadic gearbox warning
- Brief limp mode or shift shock
Common causes of P0892
- Most likelyLoose contact in relay socket or connector
- PossibleRelay with worn contacts
- PossibleWire broken by vibration
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0892 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. |
| 92 | The exact fault in that area. |
What to do next
- Note P0892 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 P0892
What does P0892 mean?
P0892 means "TCM Power Relay Sense Circuit Intermittent". 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 P0892?
Drive gently and only to a workshop. With P0892 the car can go into limp mode (reduced power) to protect itself.
Will P0892 fail an emissions test?
Yes, it can. P0892 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 P0892 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P0892 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
