The P02402 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Evaporative Emission System (EVAP), specifically related to the leak detection pump control circuit. This code is triggered when the Engine Control Module (ECM) detects a high voltage signal in the leak detection pump circuit, which can lead to improper
The P1863 trouble code is a diagnostic trouble code (DTC) that pertains to issues within the powertrain, specifically related to the transmission or transfer case. This code indicates a malfunction that may be due to an open circuit in the power contact plate of the transmission transfer case. Understanding this code is crucial for vehicle
The P1476 trouble code is associated with the evaporative emissions control system, specifically indicating an issue with the Leak Detection Pump (LDP). This code typically signifies “Insufficient Vacuum” in the EVAP system, which is responsible for capturing and recycling fuel vapors from the fuel tank to prevent them from escaping into the atmosphere. When this
The P3451 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the cylinder deactivation system, specifically related to the intake valve control circuit for cylinder 7. This code is commonly found in vehicles equipped with an engine management system that includes cylinder deactivation technology, which is designed to improve fuel efficiency
The P1054 trouble code is a manufacturer-specific diagnostic trouble code (DTC) that indicates an issue related to the air-fuel mixture or camshaft timing in a vehicle’s engine management system. This code is primarily associated with problems in the powertrain, particularly affecting fuel and air metering systems. Understanding this code is crucial for vehicle owners and
The P1402 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction within the Exhaust Gas Recirculation (EGR) system. Specifically, it generally means that the EGR metering orifice is restricted, which can lead to increased emissions and potential engine performance issues. The EGR system plays a crucial role in reducing nitrogen oxide (NOx)
The P2433 diagnostic trouble code (DTC) is a generic powertrain code related to the secondary air injection system. This code specifically indicates an issue with the air flow/pressure sensor circuit in Bank 1 of the engine. When the powertrain control module (PCM) detects a voltage or resistance that’s higher than expected from this sensor circuit,
The P007D code is a diagnostic trouble code (DTC) related to the charge air cooler temperature sensor circuit in bank 1 of the engine. This code indicates that the powertrain control module (PCM) has detected a high voltage signal from the charge air cooler temperature sensor, which is typically associated with an open circuit or
The P0284 code is a diagnostic trouble code (DTC) that indicates a cylinder 8 contribution/balance fault. This code is set when the engine control module (ECM) detects that the eighth cylinder in the firing order is not producing as much power as the other cylinders. Understanding and addressing this issue is crucial for maintaining optimal
The P115E code is a powertrain trouble code related to the fuel rail system pressure. This diagnostic trouble code (DTC) indicates that the fuel rail pressure is too high, potentially causing issues with the engine’s performance and fuel efficiency. When this code appears, it suggests that the vehicle’s powertrain control module (PCM) has detected a
The P2767 trouble code, also known as “Input/Turbine Speed Sensor B Circuit No Signal,” is a generic powertrain code related to transmission issues. This code is set when the powertrain control module (PCM) detects no signal from the input/turbine speed sensor B circuit. Understanding this code is crucial for diagnosing and resolving transmission problems effectively.
