The P0333 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the knock sensor circuit, specifically “Knock Sensor 2 Circuit High Input (Bank 2).” This code is triggered when the powertrain control module (PCM) detects a voltage input from the knock sensor that exceeds the manufacturer’s specified limits. The knock sensor
The P2237 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the oxygen sensor’s positive current control circuit for bank 1, sensor 1. This code is triggered when the Powertrain Control Module (PCM) detects a discrepancy in the current flowing to the upstream oxygen sensor, which plays a crucial role in
The P0472 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the exhaust pressure sensor circuit. Specifically, it means that the Engine Control Module (ECM) has detected a low voltage signal from the exhaust pressure sensor, which is crucial for monitoring exhaust back pressure and ensuring optimal engine performance. This code
The P1504 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Idle Air Control (IAC) valve circuit in vehicles, particularly those manufactured by Ford and some other brands. This code is triggered when the Powertrain Control Module (PCM) detects a malfunction within the IAC system, which is crucial for maintaining
The P0701 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the transmission control system’s range or performance. This code is generated when the Powertrain Control Module (PCM) detects an issue with the signals or performance of the transmission system. Vehicles equipped with automatic transmissions are particularly susceptible to this code,
The P1416 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction within the engine’s management system, specifically relating to the activation control of the Multiple Displacement System (MDS) for cylinder 6. This system is designed to improve fuel efficiency by deactivating certain cylinders under light load conditions. When the PCM (Powertrain Control
The P2107 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction within the throttle actuator control module processor. This code is primarily associated with vehicles equipped with electronic throttle control systems, commonly referred to as “drive-by-wire” systems. When the powertrain control module (PCM) detects an issue with the throttle actuator, it triggers
The P0129 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the barometric pressure reading in a vehicle’s engine management system. Specifically, it signifies that the Powertrain Control Module (PCM) has detected a barometric pressure reading that is lower than the manufacturer’s specified limit. This can lead to various performance issues,
The P0620 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the generator control circuit. This code is generic and can apply to a wide range of vehicles equipped with OBD-II systems, which have been in use since 1996. When the powertrain control module (PCM) detects an issue within the generator
The P0645 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the A/C clutch relay control circuit. This code is common across many OBD-II compliant vehicles manufactured from 1996 onwards. When the Powertrain Control Module (PCM) detects improper signals within the A/C clutch relay control circuit, it sets this code, which
The P1260 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the vehicle’s anti-theft system, specifically the Passive Anti-Theft System (PATS). This code is triggered when the system detects a potential theft condition, leading to the immobilization of the vehicle to prevent unauthorized access. Understanding and resolving this issue is crucial
