    LAUNCH 629 User's Manual 2. General Information-About OBDII/EOBD 2.1 On-Board Diagnostics (OBD) I Note: With the exception of some 1994 and 1995 vehicles, most vehicles from 1982 to 1995 are equipped with some type of first generation On-Board Diagnostics. Beginning in 1988, California’s Air Resources Board (CARB), and later the Environmental Protection Agency (EPA) required vehicle manufacturers to include a self-diagnostic program in their on-board computers.
  • Page 9 LAUNCH 629 User's Manual showed the following: • A large number of vehicles had deteriorating or degraded emissions-related components. These components were causing an increase in emissions. • Because OBD I systems only detect failed components, the degraded components were not setting codes.

    LAUNCH 629 User's Manual refers to much more gradual adjustments to the fuel calibration schedule than short-term trim adjustments. These long-term adjustments compensate for vehicle differences and gradual changes that occur over time. 2.6 OBD II Monitors An important part of a vehicle’s OBD II system is the Readiness Monitors, which are indicators used to find out if all of the emissions components have been evaluated by the OBD II system.

  • Page 16: Non-Continuous Monitors

    LAUNCH 629 User's Manual The “non-continuous” Monitors are: 1. O Sensor Monitor The Oxygen Sensor monitors how much oxygen is in the vehicle’s exhaust. It generates a varying voltage of up to one volt, based on how much oxygen is in the exhaust gas, and sends the signal to the computer.
  • Page 17 LAUNCH 629 User's Manual In order for the computer to enter closed-loop operation, the oxygen sensor must reach a temperature of at least 600°F. The oxygen sensor heater helps the oxygen sensor reach and maintain its minimum operating temperature (600°F) more quickly, to bring the vehicle into closed-loop operation as soon as possible.
