What is a TCM power input signal low?
The P0882 code (TCM Power Input Low) sets when the PCM sees less than three volts on the PCM output wires: pins 19, 28, and 38 on the C4 connector. There are four main reasons for this code to set: The PCM doesn’t send power to the TIPM to turn the relay on.
What is code P0880?
Powertrain Control Module
What the P0880 code means. A P0880 indicates that the vehicle’s Powertrain Control Module (PCM) has failed to receive data from the traction control module communication circuit. Among other things, this system allows the vehicle to calculate an engine’s RPM and optimize the delivery of fuel.
When do I get the p0882 code on my computer?
It indicates low power input. The system tests for code P0882 when you turn the ignition from Off to Run, or from Start to Run. The code sets when the computer detects less than 3.0 volts at the transmission control relay output circuits at the powertrain control module (PCM) when the PCM is energizing the relay.
Why does my car have a low voltage p0882?
Low Voltage. Code P0882 can set due to low battery voltage caused by either improper charging system operation or excessive draw during starting. With the engine running, test the alternator output with your DVOM. When running, your alternator should produce in the vicinity of 14.0 volts.
When to look for DTC p0882 in a car?
Before beginning any in-depth electronic diagnosis, check that the battery voltage is proper. A telltale sign that the battery is weak and may be causing DTC P0882 is if you require a boost to start the engine. Alternatively, perform a load test on the battery.
How to check the p0882 Dodge Transmission Control Module power input?
Prior to this the PCM verifies that the contacts are open by checking for no voltage at the switched battery terminals. After the relay is energized, the PCM monitors the terminals to verify that the voltage is greater than 3 volts. Need more information on how to fix the P0882 DODGE code?
