DTC P0500 Vehicle Speed Sensor Malfunction; DTC P0503 Vehicle Speed Sensor "A" Intermittent / Erratic / High: Description
WARNING: This page is about a different car, the 2008 Lexus IS F. However, it is still accessible from the selected car via links, so may be relevant.
The cruise control system uses the same vehicle speed signal that is sent to the ECM for the SFI system. If DTC P0500 or P0503 is detected, perform the diagnosis using the inspection procedure for DTC P0500 in the SFI system (for 2UR-GSE) (See DTC P0500 VEHICLE SPEED SENSOR "A" ). The speed signal is converted for use by the cruise control inside the ECM. Both the SFI system and the cruise control system can set DTC P0500, however, the detection conditions of the two systems are different.
