Vehicle Speed Sensor Circuit Malfunction |
DESCRIPTION
The dynamic radar cruise control system uses the same vehicle speed signal that is sent to the ECM for the SFI system. If DTC P0500 and P0503 is detected, perform the diagnosis using the inspection procedure for DTC P0500 and P0503 in the SFI system (See page
![2016 MY Sienna [12/2015 - 08/2016]; 2GR-FE (ENGINE CONTROL): SFI SYSTEM: P0500; Vehicle Speed Sensor](/t3Portal/stylegraphics/info.gif)
). The speed signal is converted for use by the cruise control inside the ECM. Both the SFI system and the dynamic radar cruise control system can set DTC P0500 and P0503, however, the detection conditions of the two systems are different.
