The P0629 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the fuel pump “A” control circuit, specifically a high voltage condition. This code is applicable to many vehicles equipped with OBD-II systems, which were mandated for all cars and trucks sold in the United States starting in 1996. When the Powertrain Control Module (PCM) detects a voltage level that exceeds

The P203C trouble code is a diagnostic trouble code (DTC) that indicates a problem with the Reductant Level Sensor ‘A’ circuit in a vehicle’s emission control system, specifically in diesel engines that utilize Diesel Exhaust Fluid (DEF). When the Powertrain Control Module (PCM) detects an unexpectedly low electrical signal from the reductant level sensor, it triggers this code. This sensor plays a crucial role in

The P0728 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the engine speed input circuit. This code is triggered when the powertrain control module (PCM) detects an intermittent signal from the engine speed sensor, which is critical for proper transmission operation. Understanding this code is essential for vehicle owners and DIY mechanics, as it can lead to significant drivability issues

The P2119 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the throttle actuator control system, specifically related to the throttle body range and performance. This code is typically triggered when the Powertrain Control Module (PCM) detects that the throttle actuator is not functioning within its expected parameters. It is crucial for vehicle owners and DIY mechanics to understand this code,

The P001A trouble code is a diagnostic trouble code (DTC) that indicates an issue with the “A” camshaft profile control circuit, specifically an open circuit in Bank 1 of the engine. This code is part of the On-Board Diagnostics II (OBD-II) system, which monitors various engine parameters to ensure optimal performance and emissions control. When the Powertrain Control Module (PCM) detects a lack of synchronization

The P2794 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the gear shift direction circuit in vehicles equipped with automatic transmissions. Specifically, it refers to a “Gear Shift Direction Circuit Low” condition. This code is triggered when the vehicle’s Engine Control Module (ECM) detects an abnormal voltage reading in the gear shift direction circuit, which is crucial for determining the

The P2850 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the automatic transmission system of a vehicle. Specifically, it refers to “Shift Fork ‘D’ Unrequested Movement,” which means that the shift fork responsible for engaging and disengaging the clutch packs or bands is moving without command from the Transmission Control Module (TCM). This uncommanded movement can lead to erratic shifting,

The P0569 trouble code is a diagnostic code that indicates a malfunction in the cruise control system, specifically related to the coast signal. This code is typically set when the Engine Control Module (ECM) detects an issue with the cruise control coast function, which is responsible for allowing the vehicle to gradually slow down when cruise control is engaged. P0569 Code Meaning P0569 Code Common

The P2602 trouble code, also known as “Coolant Pump A Control Circuit Low,” is a generic powertrain code that typically applies to vehicles equipped with electric coolant pumps. This code is particularly common in hybrid vehicles manufactured by Ford, Honda, Nissan, and Toyota. When the Powertrain Control Module (PCM) detects a low voltage condition in the control circuit for Coolant Pump A, it triggers the

The P1418 trouble code is a manufacturer-specific diagnostic code related to the secondary air injection system in certain vehicles. When this code appears, it typically indicates a malfunction in the split air circuit, which is part of the emissions control system. Understanding and resolving this issue is crucial for maintaining your vehicle’s performance and ensuring it meets emissions standards. P1418 Code Meaning P1418 Code Common
