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 or P0503 is detected, perform the diagnosis using the inspection procedure for DTC P0500 in the SFI system (COROLLA_ZRE142 RM000002Y4K087X_01.htmlfor 2ZR-FE, or COROLLA_ZRE142 RM0000012ME0G2X_01.html for 2AZ-FE). The speed signal is converted for use by the cruise control system 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.
