OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.

PIDS are the serial data that can be accessed from the vehicle computer using a scan tool. PIDS include: (cruise control on/off. brake pedal switch on/off. TCC engaged/disengaged, etc.) Long and Short Term Fuel Trim, O2 sensor cross counts, injector duration.

2024年6月2日 · PID data, or Parameter Identification data, refers to the information retrieved from a vehicle’s onboard diagnostic system during a diagnostic scan. This data encapsulates various operational parameters essential for evaluating the vehicle’s performance and …

2014年10月1日 · Each sensor is characterised by a number called PID (Parameter Identifier) used to identify the parameter. For example, the standard stipulates that the engine speed has a PID of 12. The OBD standard (updated in 2007) includes 137 PIDs. As for the modes, not all cars support all PIDs.

2018年5月1日 · P-codes, or OBD-II PIDs On Board Diagnostics “Parameter IDs”, are codes used to request data from a vehicle, used as a diagnostic tool. These codes are part of SAE standard J/1979, required to be implemented in all cars sold in North America since 1996.

2024年11月22日 · OBD2 PIDs, or Parameter IDs, are hexadecimal codes that represent specific data points within a vehicle’s onboard diagnostic system. They act as addresses for various parameters, allowing diagnostic tools to request and receive specific information from …

2024年11月9日 · OBD2 PIDs (Parameter IDs) are codes that request specific data from your vehicle’s ECU (Engine Control Unit). Each PID corresponds to a particular parameter, such as engine speed, coolant temperature, or oxygen sensor readings.

This OBD2 PID lookup tool lets you quickly find details for a specific OBD2 PID. The tool will display the available information, as well as how to construct the OBD2 request CAN frame. In addition, the tool provides an example of how the corresponding OBD2 response frame could look - and how the data is decoded to physical values.

2024年11月6日 · OBD2 PID codes are the key to unlocking your car’s hidden data. These codes, also known as Parameter IDs, are standardized identifiers used by OBD2 scanners to request specific pieces of information from a vehicle’s onboard computer.

PID (Parameter ID) : The PID field specifies the specific data parameter or sensor value being requested or reported. PIDs are used to identify the type of data in the message, such as engine RPM, vehicle speed, oxygen sensor voltage, and more.
