The P261B trouble code is a diagnostic trouble code (DTC) that indicates a problem with the coolant pump ‘B’ control circuit performance. This code is part of the OBD-II system, which monitors the vehicle’s engine and transmission performance. When the powertrain control module (PCM) detects that the coolant pump is not functioning as expected, it …
The P17F0 trouble code is a diagnostic trouble code (DTC) that indicates a problem related to the Continuously Variable Transmission (CVT) in certain vehicles, primarily Nissan models. This code specifically refers to issues detected by the Transmission Control Module (TCM), which may include symptoms like transmission judder or slipping. Understanding and addressing the P17F0 code …
Diagnose: Verify the TPS 2 signal voltage at the PCM using a scan tool. A scan tool can be used to check the TPS 2 signal voltage at various throttle blade positions. A visual inspection of the TPS 2 wiring and connector should also be performed. Having a Dodge P0221 code can be a very …
The P1174 diagnostic trouble code (DTC) is a manufacturer-specific code that primarily affects General Motors (GM) vehicles. It indicates a fuel trim imbalance in the engine’s cylinders, specifically on Bank 1. This code suggests that the engine control module (ECM) has detected an inconsistency in the air-fuel mixture across different cylinders, which can lead to …
Solution: Check the transmission revolution sensor NC (speed sensor NC) circuit for open or short. Do you own a Scion and have recently encountered a P0793 Code? This code is an intermediate shaft speed sensor “A” code that is detected by the ECM when certain conditions (a), (b) and (c) are met continuously for 5 …
The P1739 trouble code is a diagnostic trouble code (DTC) that indicates a problem in the third clutch pressure switch circuit of an automatic transmission. This code is primarily associated with vehicles equipped with electronically controlled automatic transmissions. When the powertrain control module (PCM) detects that the readings from the third clutch pressure switch are …
The P0411 diagnostic trouble code (DTC) indicates a problem with the secondary air injection system in a vehicle. This code is set when the engine control module (ECM) detects incorrect airflow in the secondary air injection system, which is designed to reduce emissions by introducing fresh air into the exhaust stream during cold starts and …
The P2195 trouble code is a diagnostic code that indicates an issue with the oxygen sensor signal in your vehicle. Specifically, it means that the oxygen sensor in Bank 1, Sensor 1 is reporting a lean condition that the engine control module (ECM) cannot correct. This code is crucial for maintaining proper fuel efficiency and …
The P2183 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Engine Coolant Temperature (ECT) Sensor 2 circuit. Specifically, it signifies that the performance or range of ECT Sensor 2 is out of the expected parameters set by the vehicle’s manufacturer. This code is part of the OBD-II system, which …
The P0440 code is a generic powertrain code related to the vehicle’s Evaporative Emission Control (EVAP) system. When the engine control module (ECM) detects a malfunction or leak in the EVAP system, it triggers this diagnostic trouble code (DTC). Understanding and addressing the P0440 code is crucial for maintaining your vehicle’s emissions control system and …
