Code P075, VSS Signal Interrupt: Notes

This test compares vehicle speed to manifold pressure. Change in MAP must correspond with a change in vehicle speed. PCM will ignore test if conditions for engine idle are present. If vehicle speed changes 14 MPH (VIN Y) or 16 MPH (VIN 9) or greater in one second Code P075 will set. If failure occurs 10 times in 10 seconds, code will remain current for the entire ignition cycle.
