If you have changed the proper sensor then you may need to have the cam shaft looked at.

SOURCE: On my Toyota Sienna 2008, my check engine light,

On most Toyota's that are equipped with Cruise Control (Vehicle Speed Control or "VSC") and with Traction Control System (TCS or "Trac") all of these lights will come on at the same time if the Engine Control Module (ECM) determines that there is a fault in the engine management system that 1. Prevents the engine from being properly controlled. 2. Prevents the VSC from being properly controlled 3. Prevents the TCS from being properly controlled 4. Any combination of items 1,2, and 3.
Most of the time it is caused by a single fault in the engine management system. Fault codes are codes that are output by the ECM to let a diagnostician know which of the many systems, that are monitored by the ECM, is malfunctioning. To find out what the actual cause is, you must scan the ECM for fault codes then use this information to begin diagnosis of the system that the fault codes point to.

SOURCE: My Toyota Sienna shows VSC light on the broad.

Hi there,

If you've had your vehicle computer codes read and determined no issue with the VSC circuit, then you just need to cancel the warning light.

I've made up the following instructions, on how to clear VSC & TRAC Warning lights:



Zero Point Calibration of Yaw Rate and Deceleration Sensors Using Paper Clips (or jumper wires).

First, locate the 16-pin ODB II connector under the steering wheel (beneath the dash). The pins are numbered sequentially backwards from right to left (from the wide side of the connector looking at it from underneath).


Take two normal-sized paper clips (or suitable jumper wires). If using paper clips, straighten one edge of one of the paper clips. For the other, bend it open to a 90-degree angle (like an elbow).


Insert one paper clip/wire into pin # 14 (Ts), and the other paper clip/wire into pin # 4 (CG) of the OBD II connector - DO NOT allow the paper clips/wires to make contact at this point.
Refer to diagram below:

1. Ensure the shift lever is in "P" range.


2. Turn the ignition switch to "ON" (not start).


3. Momentarily touch the two paper clips/wires together (short) and separate again (open) - Repeat this process 5 times (within 8 seconds of turning ignition on).

Verify that the VSC indicator light is illuminated, indicating the Recorded Zero point is erased.


4. Turn the ignition switch "OFF".


5. Remove both paper clips/jumper wires from the OBD II connector.


6. Turn the ignition switch "ON" (not start) - wait until VSC warning light turns off (approx. 20 seconds), then wait 2 seconds.


7. Turn the ignition switch "OFF".


9. Re-insert paper clips/jumper wires to terminals #4 & #14 of the OBD II connector (as per above diagram).


10. Turn the ignition switch "ON" (not start) - VSC warning light should remain illuminated for 4 seconds, then start flashing at 0.13 second intervals.


12. After VSC warning light flashes for 2 seconds, turn the ignition switch "OFF".


13. Remove paper clips/jumper wires from the OBD II connector.



Drive your vehicle to confirm VSC & TRAC warning lights have been reset and no longer illuminate.

Disabling the light doesn't fix the problem, you should have this diagnosed by connecting a diagnostic code reader that can communicate with the traction control system, then go from there.

Check engine, vsc, track off light come on in same time


the vsc light comes on when ever the check engine light comes on, this is because the vsc cant operate correctly when engine isnt running right so computer shuts it down and light turns on, you need to have the computer scanned for codes to figure out why check engine light came on,the codes that are stored will point you in the right direction of the problem, autozone and other auto part stores will scan for free,
