DEFINITIONS
OBDII Trip - A vehicle start and drive cycle such that all once per trip diagnostic monitors have run.
Key Start - A vehicle start and run cycle of at least 20 seconds.
Warm-up Cycle - A vehicle start and run cycle such that the engine coolant must rise to at least 160°F and must rise by at least 40°F from initial start up. To count as a warm-up cycle, no faults may occur during the cycle.
CLARIFICATIONS
Although they both refer to the same part, the terms Transmission Range Sensor (TRS) and Manual valve Lever Position Sensor (MVLPS) have been used interchangeably in the past. In this, and future data, all references to TRS and MVLPS will be TRS.
Also, the terms PRNDL switch and Transmission Range Switch have been used interchangeably while they refer to the same part. In this and future data, the term PRNDL switch will be used. This is being done primarily to avoid the confusion between Transmission Range Sensor (TRS) and Transmission Range Switch (also TRS).
To further clarify the issue, a transmission will have either a Transmission Range Sensor (TRS) or a combination PRNDL Switch and [1][2]Park/Neutral position switch. A transmission with a TRS cannot have a PRNDL Switch or a Park/Neutral position switch.
