by

The P0125 code is a diagnostic trouble code (DTC) that indicates an issue with the engine’s coolant temperature. Specifically, it means “Insufficient Coolant Temperature for Closed Loop Fuel Control.” This code is triggered when the engine control module (ECM) detects that the engine is not reaching its normal operating temperature within a specified time after … Read more

Code P0603: What It Is And How To Fix It?

by

Code P0603 is a diagnostic trouble code (DTC) that indicates an issue with the Internal Control Module Keep Alive Memory (KAM) in your vehicle. This code is generated when the Powertrain Control Module (PCM) detects an error in its KAM self-test. The KAM is a crucial component of your vehicle’s computer system, responsible for storing … Read more

Code P2187: What It Is And How To Fix It?

by

Code P2187 is a diagnostic trouble code (DTC) that indicates a lean fuel condition at idle in bank 1 of the engine. This means the engine is receiving too much air or not enough fuel when idling. The powertrain control module (PCM) detects this imbalance through various sensors and triggers the check engine light. Understanding … Read more
