P1258 Isuzu Description

In order to reduce the engine temperature the Powertrain Control Module (PCM) has the ability to disable a number of fuel injectors during an engine over temperature condition. The PCM considers the engine over temperature whenever the Engine Coolant Temperature (ECT) reaches a predetermined temperature. This DTC sets in order to show that the PCM detected an over temperature condition and that the system engaged the protection mode.
