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.
On-board diagnostics. Various views of a "MaxScan OE509" – a fairly typical onboard diagnostics (OBD) scanner, 2015. On-board diagnostics ( OBD) is a term referring to a vehicle's self-diagnostic and reporting capability. In the United States, this capability is a requirement to comply with federal emissions standards to detect failures that ...
Oxygen sensor. An oxygen sensor (or lambda sensor, where lambda refers to air–fuel equivalence ratio, usually denoted by λ) or probe or sond, is an electronic device that measures the proportion of oxygen (O 2) in the gas or liquid being analyzed. It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Günter ...
Unified Diagnostic Services (UDS) is a diagnostic communication protocol used in electronic control units (ECUs) within automotive electronics, which is specified in the ISO 14229-1. [1] It is derived from ISO 14230-3 and the now obsolete ISO 15765-3 (Diagnostic Communication over Controller Area Network (DoCAN) [2]). 'Unified' in this context ...
The M111.920 [ 1] is a 1.8 L (1,799 cc) 16 valve engine with bore and stroke of 85.3 mm × 78.7 mm. It produces 90 kW (122 PS; 121 hp) of power at 5500 rpm and 170 N⋅m (125 lb⋅ft) at 4200 rpm. Starting with 1996 it has a variant called the M111.921 [ 2] which has a MAF (Mass Air Flow)-sensor instead of MAP-sensor on the first one, and using ...
Electronic stability control ( ESC ), also referred to as electronic stability program ( ESP) or dynamic stability control ( DSC ), is a computerized technology [ 1][ 2] that improves a vehicle's stability by detecting and reducing loss of traction ( skidding ). [ 3] When ESC detects loss of steering control, it automatically applies the brakes ...
MAP sensor. The manifold absolute pressure sensor ( MAP sensor) is one of the sensors used in an internal combustion engine 's electronic control system. Engines that use a MAP sensor are typically fuel injected. The manifold absolute pressure sensor provides instantaneous manifold pressure information to the engine's electronic control unit (ECU).
A check engine light or malfunction indicator lamp ( MIL ), is a tell-tale that a computerized engine-management system used to indicate a malfunction or problem with the vehicle ranging from minor (such as a loose gas cap) to serious (worn spark plugs, engine problems or a faulty oil valve, etc.). Found on the instrument panel of most ...
