Q: Vtrack and engine light error on

asked by on

Just had work on my Toyota sequoia 2006 v8. The water pump and timing belt got replaced. Now I get vtrack and engine light errors. It drives well but I'm worried of a larger problem any advice is appreciated. Prior to this there was no errors. The water pump was leaking. I had recently had it diagnosed by Toyota dealer. So being on a budget rather than paying over 1500 for work i had it done somewhere else. My mechanic is a good, fair person. I have been with them for many years. I just would like to know more. I'm a sort of worry wort.

My car has 150000 miles.
My car has an automatic transmission.

Hello, The VSC Trac light is related to your traction control system which means that the system has likely detected some kind of fault in the system and may be trying to inadvertently engage the system. The traction control system monitors the steering and stability of the vehicle and engages when loss of traction has been detected. This is done by the use of electronic sensors at each of the four wheels that communicate with the Powertrain Control Module (PCM) regarding steering performance and stability in adverse weather conditions. The traction control system works by reducing engine speed and determining which wheel to apply brake pressure to in order to prevent the vehicle from sliding. The anti-lock braking system and the traction control system work together to maintain the stability of the vehicle. The computer uses this information received from electronic sensors regarding the rotational speed of each wheel, the horizontal motion of the vehicle, and the vertical motion of the vehicle to determine how to direct the traction control system or the anti-lock braking system to best control the vehicle when needed. When this warning indicator light comes on in the dashboard, this could be an indication of several issues such as faulty wheel speed sensors, a faulty steering angle sensor, a faulty rotational speed sensor or a problem with the steering rack. In some cases, the traction control system may simply need to be reprogrammed. I would recommend having a professional from YourMechanic come to your location to properly diagnose your traction control system.
