Question When driving, my speedometer is jumping while accelerating and braking. What may be the culprit in this issue? I have thought maybe a speed sensor, however, there is 2 I believe, if this could be it which should i go for changing?
Answer Chris,
Most cars have one main vehicle speed sensor (vss). The VSS in front wheel drive cars is mounted in the transmission. A gear in the tranny turns a small gear on the VSS. If a tooth of the gear on the VSS is damaged, you can get that erratic speedometer jumping like you're experiencing. A malfunctioning VSS can cause problems with shifting and with the activation of the anti-lock braking system and cruise control. Have your mechanic inspect your VSS and replace if necessary.
Good luck!
