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 …
When it comes to diagnosing and repairing Cadillac vehicles, one of the most common issues is the P0442 code, which stands for “Evaporative Emission (EVAP) System Small Leak Detected.” This code can be triggered by a variety of issues, such as a faulty fuel system, a leak in the EVAP system, or a problem with …
The Ford P061A Code is a diagnostic trouble code that indicates an internal control module torque performance issue. This diagnostic trouble code (DTC) is triggered when the measured engine torque value exceeds the maximum allowable engine torque value. The causes of this code can range from aftermarket performance products to PCM programming errors. To diagnose …
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 …
