The P26C8 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the vehicle’s chassis control module, specifically that it has requested the illumination of the Malfunction Indicator Lamp (MIL). This code is part of the OBD-II system, which monitors various vehicle functions to ensure optimal performance and compliance with emissions regulations. …
The P3051 trouble code is an OBD-II diagnostic trouble code that indicates a specific malfunction within a vehicle’s powertrain system. This code is often manufacturer-specific, meaning its exact definition can vary between different vehicle brands. Generally, P3051 signals issues related to the hybrid propulsion system or electrical components like the DC/DC converter in electric and …
The P1391 trouble code is a manufacturer-specific diagnostic code that typically indicates an intermittent loss of signal from either the camshaft position (CMP) sensor or the crankshaft position (CKP) sensor. This code is commonly found in Chrysler, Jeep, and Dodge vehicles, particularly those with the 4.0L inline-six engine. When the powertrain control module (PCM) detects …
The P0050 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. This code is triggered when the Engine Control Module (ECM) detects that the heater circuit for this specific sensor is malfunctioning. The oxygen sensor …
The P0147 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the oxygen sensor heater circuit for Bank 1, Sensor 3. This code is triggered when the vehicle’s Powertrain Control Module (PCM) detects that the oxygen sensor does not reach its operating temperature within the expected time frame. The oxygen sensors …
The P1284 trouble code is a diagnostic trouble code (DTC) that indicates an issue related to the engine’s air-fuel mixture, specifically referring to the Air Fuel Ratio (A/F) Sensor 1 on Bank 2. This code can trigger the check engine light and may lead to various performance issues if not addressed promptly. Understanding the meaning …
The P0199 trouble code is a diagnostic trouble code (DTC) that indicates an intermittent fault in the engine oil temperature sensor circuit. This code is triggered when the Powertrain Control Module (PCM) detects that the voltage signal from the engine oil temperature sensor is sporadically out of range. The engine oil temperature sensor plays a …
The P2238 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the oxygen sensor’s positive current control circuit, specifically for Bank 1 Sensor 1. This code is part of the OBD-II system, which monitors various components of a vehicle’s engine and emissions systems. When the powertrain control module (PCM) detects a …
The P20BB diagnostic trouble code (DTC) signifies a problem with the reductant heater ‘A’ control circuit, indicating that the powertrain control module (PCM) has detected insufficient voltage in the circuit. This issue is primarily associated with diesel engines equipped with selective catalytic reduction (SCR) systems, which utilize diesel exhaust fluid (DEF) to reduce harmful emissions. …
The P1175 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the fuel trim cylinder balance, specifically in bank 2 of the engine. This code typically arises when the engine control module (ECM) detects a significant imbalance in the air-fuel ratio between cylinders. Such imbalances can lead to various performance issues, …
