The P0506 code is a diagnostic trouble code (DTC) that indicates an issue with the vehicle’s idle control system. Specifically, it means that the engine’s idle speed is lower than expected. This code is typically set when the powertrain control module (PCM) detects that the engine is idling below the predetermined RPM level for a …
The P0789 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Shift Timing Solenoid “A” in a vehicle’s automatic transmission system. This solenoid plays a critical role in controlling the timing of gear shifts, ensuring the smooth operation of the transmission. When the powertrain control module (PCM) detects an intermittent …
The P0839 trouble code indicates a malfunction within the four-wheel drive (4WD) switch circuit, specifically signaling that the circuit is registering a high voltage. This code is applicable to many vehicles equipped with OBD-II systems, which have been in use since 1996. The 4WD switch circuit is crucial for controlling the engagement of the vehicle’s …
The P24A5 trouble code is an OBD-II diagnostic trouble code that indicates a malfunction in the Exhaust Gas Recirculation (EGR) cooler bypass control system, specifically stating that the bypass control is stuck or open on Bank 1. This code is primarily associated with diesel engines, particularly those equipped with EGR systems designed to reduce nitrogen …
The P2407 trouble code is a diagnostic trouble code (DTC) that indicates an issue within the Evaporative Emission Control System (EVAP). Specifically, it refers to the “Evaporative Emission System Leak Detection Pump Sense Circuit Intermittent/Erratic.” This code is triggered when the Powertrain Control Module (PCM) detects an intermittent or erratic signal from the leak detection …
The P2402 trouble code is related to the Evaporative Emission (EVAP) system in vehicles. Specifically, it indicates a problem with the EVAP system leak detection pump control circuit. When this code is triggered, it means the engine control module (ECM) has detected a higher than expected voltage in the circuit that controls the leak detection …
The P1870 diagnostic trouble code (DTC) is a manufacturer-specific code used by General Motors vehicles. It indicates a transmission component slipping condition detected by the powertrain control module (PCM). This code is commonly associated with issues in the torque converter clutch (TCC) system or internal transmission components. P1870 Code Meaning P1870 Code Common Causes Transmission …
The P1E00 trouble code is associated with hybrid and electric vehicles, specifically indicating a general fault within the hybrid powertrain control module. This code serves as a warning that the vehicle’s electric system is not performing as expected, often requiring further diagnostics to identify the underlying issue. While it may not pinpoint a specific problem, …
The P3438 trouble code is an OBD-II diagnostic code that indicates a performance issue within the cylinder 5 exhaust valve control circuit. This code is often triggered when the Engine Control Module (ECM) detects a problem with the voltage or resistance in the circuit, which can lead to various engine performance issues. Understanding this code …
The P1189 trouble code is a diagnostic trouble code (DTC) that indicates a problem related to the fuel control system, specifically concerning Bank 2 Sensor 1 in many vehicles, particularly in BMW models. This code typically arises when the Engine Control Module (ECM) detects that the air-fuel mixture is excessively lean, leading to improper fuel …
