P2507 Code - ECM/PCM Power Input Signal Low

Quick Answer

When the ignition switch is turned "ON", the battery voltage is applied from the battery to the Powertrain Control Module (PCM)/Engine Control Module (ECM) through the main relay. Common causes include Low battery voltage, Faulty Powertrain Control Module (PCM)/Engine Control Module (ECM), ECM/PCM harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2507 Description

When the ignition switch is turned "ON", the battery voltage is applied from the battery to the Powertrain Control Module (PCM)/Engine Control Module (ECM) through the main relay. In case that the ignition switch is turned "OFF", the ECM/PCM is supplied with power through the battery power input line to control the basic operation of the vehicle. The ECM/PCM set the OBDII code when the ECM/PCM Power Input is out of factory specifications.
