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.
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. [1] It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Günter Bauman. [1]
The 2007 Outlook and GMC Acadia went into production in late 2006, followed by the 2008 Enclave in mid-2007, and the 2009 Chevrolet Traverse in mid-2008. Lambda vehicles feature easily accessible three-row seating. They were supplied with the LY7 3.6-liter V6.
Service / Mode $05 displays the oxygen sensor monitor screen and the test results gathered about the oxygen sensor. There are ten numbers available for diagnostics: $01 Rich-to-Lean O2 sensor threshold voltage; $02 Lean-to-Rich O2 sensor threshold voltage; $03 Low sensor voltage threshold for switch time measurement
The Lambda coefficient (λ) is obtained from the relationship between air and gasoline involved in combustion of the mixture. It is a measure of the efficiency of the gasoline engine by measuring the percentage of oxygen in the exhaust. When gasoline engines operate with a stoichiometric mixture of 14.7: 1 the value of lambda (λ) is "1".

Holden has built its own 3.2 L (3,195 cc) version of the High Feature engine in Australia produced between 2005 and 2010 with a bore and stroke of 89 mm × 85.6 mm (3.50 in × 3.37 in). Branded with the Alloytec name like the 3.6L version, this version produces 227 hp (169 kW; 230 PS) at 6600 rpm and 297 N⋅m (219 lb⋅ft) at 3200 rpm.
The fuel-injection system was a Motronic MP3.1, which was later upgraded by Bosch as the Motronic M4.6 MPI on 1.1- and 1.3-L engines, adding multiport fuel injection. It had a three-way catalytic converter and a Lambda sensor. [4]
