diagnostic reader and or workshop time required to
to fix both VSC and engine light faults /codes
VSC is brake /traction related ..... this is one explanation
It would appear that system braking, traction control, and possibly some anti rollover control is dis abled if this warning light is on. So it is both fuel in efficient and possibly dangerous to drive with this light on.
engine light
there are stored fault codes in the engine computer module pointing to faulty sensors on the car needing to be checked or replaced
that code 356 is a bad coil. if it is completely dead than you now have a 5 cylinder car.... very bad not only on mpg but also on the life of the engine. when you have a "dead hole" it can affect the other cylinders and you have misfire codes for all 6..... this could mean you simply need a tune up or that there is something affecting all cylinders. check for a vacuum leak after the air flow sensor, or a ruptured fuel pressure regulator (remove the vacuum line at the regulator and smell for gas cause there should not be gas on that side of the diaphragm) fouled spark plugs, clogged exhaust or catalytic converter, stuck open or dirty EGR valve to name a few. change that #6 coil first and at least inspect or change the spark plugs... c1201 relates to a communication stop between ECU's , don't assume that as the vsc lights etc were illuminated then that is the system that is faulty. It is most likely that the fault is within the engine system but with vehicles equipped with vsc all systems are linked so a fault with one will log a code in all others ( normally a communication stop code as you have)
I would advise fixing the engine codes first then get the other systems checked out
Whenever engine fault codes set, VSC is disabled and lights come on. P0020 shows failing cam shaft position sensor , recommend replace clear codes and recheck. gas spill was coincidental.
hello, this code usually comes up in conjunction with another code, it just means that another computer on the car can not communicate with the ECM, are there any other codes besides this, is the abs/VSC, TRac cruise control or 4x4 lights on?
When the lights come on a fault is stored in the computer, you will need to read this fault to determine the cause.
Keep in mind that you need to have the codes pulled for the check engine lamp. Anytime a fault is detected and the check engine lamp comes on then both the VSC and Traction control systems are disabled/shut down by the computer as a "fail-safe" function.
vsc shuts down any time check engine light comes on. repair engine light problem, reset computer monitoring system and vsc light will go off. must scan computer to pull codes for check engine light and go from there.
Most major Auto Parts stores Advance/Auto Zone will get the diagnostics codes from the cars computer and tell you why the light is on and what the problem is if there is a problem.
the vsc light will come on with check eng light it disables traction control when its on when you fix or clear ck eng lite itll go off I have a 04 sienna it has bad cat conv and it comes on every couple of months I just clear it cause a cat costs like400 eventually ill fix it right.
