CODE 11 VEHICLE SPEED SENSOR (VSS) CIRCUITCode Chart 11:
Vehicle Speed Sensor Circuit:
CIRCUIT DESCRIPTION:
Vehicle speed information is provided to the ECU by the Vehicle Speed Sensor (VSS), which is a Permanent Magnet (PM) generator, located in the transaxle. The PM generator produces a pulsing voltage whenever vehicle speed is over 3 mph. The A/C voltage level and the number of pulses increases with vehicle speed. The ECU then converts the pulsing voltage to a mph signal.
TEST DESCRIPTION: Numbers below refer to the circled numbers on the diagnostic chart.
1. Code 11 will set if vehicle speed equals 0 mph when:
^ Engine speed is between 1800 and 4400 rpm.
^ Vehicle speed is greater than 3 mph.
The PM generator only produces a signal if the drive wheels are turning greater than 3 mph.
DIAGNOSTIC AIDS:
An intermittent may be caused by a poor connection, rubbed through wire insulation or a wire broken inside the insulation. Inspect ECU harness connector for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, poor terminal to wire connection and damaged harness.
