The P2BAC diagnostic trouble code (DTC) is associated with excessive nitrogen oxide (NOx) emissions that occur when the exhaust gas recirculation (EGR) system is deactivated. This code is primarily relevant for diesel engines equipped with EGR systems, as it indicates that NOx levels have exceeded permissible limits due to a malfunction in the EGR system …
The P250E trouble code is a diagnostic trouble code (DTC) that indicates an issue with the engine oil level sensor circuit, specifically when it is detected as intermittent or erratic. This code is applicable to many OBD-II compliant vehicles manufactured from 1996 onwards. The engine oil level sensor plays a critical role in monitoring the …
The P06DD diagnostic trouble code (DTC) is related to engine oil pressure control issues. This code indicates that the engine’s oil pressure control system is not functioning as expected, specifically that it’s stuck in the “off” position. Understanding and addressing this code promptly is crucial for maintaining your vehicle’s engine health and performance. P06DD Code …
The P1456 diagnostic trouble code (DTC) is related to the Evaporative Emission Control (EVAP) system, specifically indicating a leak detected in the fuel tank area. This code is commonly found in Honda and Acura vehicles, though it may appear in other makes as well. When your vehicle’s onboard computer detects a small leak in the …
The P042F trouble code is a diagnostic trouble code (DTC) that indicates a problem with the Exhaust Gas Recirculation (EGR) system, specifically that the EGR valve control is stuck in the closed position. This code is applicable to OBD-II vehicles and can trigger a check engine light, prompting vehicle owners and mechanics to investigate further. …
The P1748 trouble code is associated with the Electronic Pressure Control (EPC) system in automatic transmissions. This code indicates a malfunction in the EPC solenoid or circuit, which can lead to transmission performance issues. When this code appears, it’s crucial to address the problem promptly to prevent further damage to the transmission. P1748 Code Meaning …
The P1152 trouble code is related to the vehicle’s oxygen sensor system and indicates a lack of switching in the upstream heated oxygen sensor (HO2S) on bank 2. This code suggests that the sensor is detecting a consistently rich fuel mixture, which can lead to poor engine performance and increased emissions. P1152 Code Meaning P1152 …
The P0AA6 code is a diagnostic trouble code (DTC) that indicates a “Hybrid Battery Voltage System Isolation Fault.” This code is particularly relevant for hybrid and electric vehicles, where the high-voltage battery system must maintain electrical isolation from the vehicle’s chassis to ensure safety and functionality. When the powertrain control module (PCM) detects a fault …
The P0688 diagnostic trouble code (DTC) indicates an issue with the ECM/PCM power relay sense circuit, specifically that it is open. This means that the powertrain control module (PCM) has detected a problem in the circuit that supplies it with voltage. The code can lead to various symptoms, including starting issues and engine performance problems, …
The P0649 trouble code is a generic diagnostic code that indicates a malfunction in the speed control lamp control circuit. This code is typically set when the powertrain control module (PCM) or another relevant control module detects an issue with the circuit responsible for controlling the speed control (cruise control) indicator lamp in the instrument …
