DTC P0500 Vehicle Speed Sensor Malfunction

DTC P0503 Vehicle Speed Sensor "A" Intermittent / Erratic / High

DESCRIPTION The cruise control system uses the same vehicle speed signal that is sent to the ECM for the SFI system.

If DTC P0500 is detected, perform the diagnosis using the inspection procedure for DTC P0500 in the SFI system. 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.
