The P0730 trouble code is a diagnostic trouble code (DTC) indicating an incorrect gear ratio detected by the vehicle’s transmission control module (TCM). This code is commonly associated with automatic transmissions and signifies that the TCM has identified a discrepancy between the expected and actual gear ratios during operation. The P0730 code can lead to

The P0191 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the fuel rail pressure sensor circuit, specifically related to its range or performance on Bank 1 of the engine. This code is part of the OBD-II system, which monitors various vehicle components to ensure optimal performance and emissions standards. When

The P0336 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the crankshaft position sensor (CKP) circuit. Specifically, it refers to the “A” circuit range/performance of the crankshaft position sensor. This code is set when the powertrain control module (PCM) detects that the signal from the crankshaft position sensor is outside

The P0506 trouble code indicates an issue with the Idle Air Control (IAC) system, specifically that the engine’s idle speed is lower than expected. This code is applicable to all OBD-II equipped vehicles and is categorized as a generic powertrain code. When the Powertrain Control Module (PCM) detects that the engine idle speed is below

The P0157 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the oxygen sensor circuit for Bank 2, Sensor 2. Specifically, it means that the voltage output from this sensor is lower than expected, which can affect the engine’s performance and emissions control. Understanding this code is essential for vehicle owners

The P0087 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the fuel rail or system pressure being too low. This code is part of the On-Board Diagnostics II (OBD-II) system, which is standard in most vehicles manufactured since the mid-1990s. When the Powertrain Control Module (PCM) detects that the fuel

The P2181 trouble code is a diagnostic trouble code (DTC) that indicates a performance issue with your vehicle’s cooling system. Specifically, it signals that the engine is not reaching or maintaining the optimal operating temperature, which can lead to various performance issues and potential engine damage. This code is often triggered when the engine coolant

The P2138 trouble code is a generic OBD-II diagnostic trouble code that indicates a problem with the throttle/pedal position sensor circuit. Specifically, it signifies that there is a voltage correlation issue between the Accelerator Pedal Position (APP) sensor and the Throttle Position (TP) sensor. This code can lead to various performance issues in a vehicle,

The P0500 trouble code indicates a malfunction related to the Vehicle Speed Sensor (VSS). This sensor is crucial for providing accurate speed readings to the vehicle’s Engine Control Module (ECM) or Powertrain Control Module (PCM). When the PCM detects an issue with the VSS or receives incorrect speed data, it triggers the P0500 code. This

Trouble code P0108 is a diagnostic trouble code (DTC) that indicates a problem with the manifold absolute pressure (MAP) sensor or barometric pressure sensor circuit. Specifically, it signifies that the Powertrain Control Module (PCM) has detected a high voltage signal from the MAP sensor, which is outside the normal operational range. This can lead to

The P2646 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the rocker arm actuator system, specifically related to the performance or functionality of the actuator on Bank 1 of the engine. This code is commonly associated with vehicles equipped with Variable Valve Timing (VVT) systems, such as Honda’s VTEC (Variable
