Circuit Description

WARNING: This page is about a different car, the 2000 Saturn LW2 and 2000 Saturn LS2. However, it is still accessible from the selected car via links, so may be relevant.

Limp home mode is a reduced power condition the vehicle enters after certain faults. In this mode, throttle position is limited to 3.7-9.8 percent. This DTC will set if TP sensor falls to less than 3.7 percent or opens to greater than 9.8 percent while vehicle is in limp home mode. This DTC results in fuel cut-off and engine will not start.
