The P2859 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the clutch disengagement performance in a vehicle’s transmission system. Specifically, it refers to “Clutch ‘A’ Pressure Disengagement Performance/Too Low.” This code is commonly associated with vehicles equipped with automatic transmissions, particularly those utilizing a continuously variable transmission (CVT) or dual-clutch systems. When this code is triggered, it suggests that the

The P1035 trouble code is a diagnostic trouble code (DTC) that signifies a malfunction in the heated oxygen sensor (HO2S) 1, bank 1, heater control circuit. This code is part of the OBD-II system, which monitors various components of a vehicle’s engine and emissions systems. When the P1035 code is triggered, it indicates that the vehicle’s computer has detected an issue with the oxygen sensor’s

The P1659 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Electronic Throttle Control System (ETCS) control relay. Specifically, it signifies that the control relay is not functioning as expected, which can lead to a loss of throttle response and potentially unsafe driving conditions. This code is often associated with vehicles equipped with drive-by-wire technology, where the throttle is controlled

The P2241 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the oxygen sensor’s positive current control circuit, specifically on bank 2 of the engine. This code is triggered when the Powertrain Control Module (PCM) detects that the voltage signal from the upstream oxygen sensor (O2 sensor) is lower than expected. The O2 sensor plays a critical role in monitoring the

The P1237 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the fuel pump secondary circuit. This code is primarily associated with issues in the Fuel Pump Driver Module (FPDM) or the wiring connected to it. The FPDM is responsible for controlling the fuel pump’s operation, ensuring the engine receives the appropriate amount of fuel for optimal performance. When this code

The P1026 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction related to the crankshaft position sensor circuit. This code is part of the OBD-II system, which monitors various components of the vehicle’s engine and powertrain. When the P1026 code appears, it typically signals that the Engine Control Module (ECM) has detected an issue with the crankshaft position sensor or its circuit.
