The P0102 trouble code indicates a problem with the Mass Air Flow (MAF) sensor circuit, specifically that the input signal from the MAF sensor is lower than expected. This sensor plays a critical role in measuring the amount of air entering the engine, which helps the engine control module (ECM) adjust the fuel-air mixture for
The P0022 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the camshaft timing in vehicles equipped with variable valve timing (VVT) systems. Specifically, it refers to the “Intake A Camshaft Position – Timing Over-Retarded (Bank 2).” This code is triggered when the engine control module (ECM) detects that the intake
The P144C trouble code is an OBD-II diagnostic code that indicates a problem with the Evaporative Emission Control System (EVAP). Specifically, it refers to the performance of the EVAP system purge flow during conditions of boost, typically in turbocharged vehicles. This code is triggered when the Powertrain Control Module (PCM) detects that the purge valve
The P0400 trouble code indicates an “Exhaust Gas Recirculation (EGR) Flow Malfunction.” This code is triggered when the Engine Control Module (ECM) detects that the flow of exhaust gases through the EGR system is insufficient or not functioning as expected. The EGR system plays a crucial role in reducing nitrogen oxide (NOx) emissions by recirculating
The P1151 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the heated oxygen sensor (HO2S) in Bank 2 of an engine, particularly in Ford vehicles. This code specifically refers to the “Lack of HO2S-21 Switch, Sensor Indicates Lean” condition, which means the engine control module (ECM) has detected that the
The P0170 trouble code indicates a fuel trim malfunction in Bank 1 of the engine, which means that the Powertrain Control Module (PCM) has detected that the fuel trim values are outside the manufacturer’s specified range. This can result in an incorrect air-fuel mixture, leading to various performance issues. Understanding this code is crucial for
The P0522 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the engine oil pressure sensor or switch circuit. Specifically, it signifies that the Powertrain Control Module (PCM) has detected a low voltage signal from the engine oil pressure sensor. This sensor plays a crucial role in monitoring the oil pressure
The P0051 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the heater control circuit of the heated oxygen sensor (HO2S) located in Bank 2, Sensor 1 of your vehicle’s engine. This code is part of the OBD-II system, which monitors various components to ensure optimal engine performance and emissions control.
The P0103 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the Mass Air Flow (MAF) sensor circuit. Specifically, it signifies that the Engine Control Module (ECM) has detected a high voltage signal from the MAF sensor, which can lead to improper air-fuel mixture calculations and affect engine performance. Understanding this
The P1148 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the air-fuel ratio (AFR) sensor in Nissan vehicles. Specifically, it signifies that the closed-loop control function for bank 1 is not operating correctly, which can lead to various performance issues. Understanding this code is essential for vehicle owners and DIY
The P0015 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the camshaft timing in vehicles equipped with variable valve timing (VVT) systems. Specifically, it refers to the “B” camshaft position timing being over-retarded for Bank 1. This can lead to various performance issues, including poor fuel efficiency, rough idling, and
