DTC |
P050013 |
Vehicle Speed Sensor "A" Circuit Open |
|
DTC |
P05001F |
Vehicle Speed Sensor "A" Circuit Intermittent |
DESCRIPTION
The cruise control system uses the same vehicle speed signal that is sent to the ECM for the SFI system. If DTC P050013 and P05001F are detected, perform the diagnosis using the inspection procedure for DTC P050013 and P05001F 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 P050013 and P05001F, however, the detection conditions of the two systems are different.
