What is a TCM power relay sensor?
The transmission control relay (TCR) is used to supply power to the transmission solenoid pack during normal operation. The relay is controlled by the powertrain control module (PCM) and/or transmission control module (TCM).
What is P0890 code?
P0890 code definition Applying only to vehicles with a traction control system, a P0890 trouble code indicates a fault in the traction control module communication circuit. The traction control module communication circuit also helps with engine timing and other things while the vehicle is in operation.
How does a Transmission Control Module ( TCM ) relay work?
When this condition is verified, the PCM/TCM activates the relay, and power can be supplied to the shift solenoids. When all required conditions are met, the PCM/TCM supplies power to the relay and the output from the relay is then fed back to the control unit via a dedicated sensing circuit.
What is the power relay control circuit code?
The power relay control circuit is a circuit within the transmission electrical system. The electrical value (s) of the power relay control circuit must go beyond the functional parameters in order for the TCM to recognize a problem and then proceeds to turn on the check engine light in the instrument cluster with code P0886.
What is the fault code for a Hyundai?
P0244 Turbocharger/Supercharger Wastegate Sol. ‘A’ Range/Performance P0245 Turbocharger/Supercharger Wastegate Sol. ‘A’ Low P0246 Turbocharger/Supercharger Wastegate Sol. ‘A’ High
What is the DTC code for a Hyundai?
In this article, you will find a complete list of Hyundai Trouble Codes. This list contains more than the Hyundai Check Engine Codes. Here you will find Hyundai ABS, Airbag, and Transmission DTC codes. P0244 Turbocharger/Supercharger Wastegate Sol.

What does the code p0882 mean on a TCM?
It’s through operation of these output devices that the TCM controls transmission operation. Like any other electronic device, the TCM must have proper power and ground. Code P0882 indicates there isn’t enough power getting to the transmission module. This is usually due to a problem with the power input circuit.
Why is the power supply to the TCM low?
There won’t be enough voltage getting to the TCM is the battery isn’t up to snuff. The battery should be charged or replaced as needed and the code cleared. A relay is used to supply power to the TCM. Since relays are usually easy to access and test, this is the next step.
