Check the wiring harnesses for bare or brittle spots. If none are found replace the spark plugs, all of them and spark plug wires. I know these are still fairly new but that is the next step. If you have over 60,000 miles on the vehicle it could be an issue with the timing chain but my experience tells me replace the crank Position sensor first if none of the other steps yield any results. Because these vehicles come with the power train warranties they do you can't really trust the Dealer Mechanics because they will do anything they can to prolong this to get the vehicle out of warranty.

The tcs light will come on whenever the engine light is on, this is because the tcs cant operate correctly when engine is not running good so its shut down by the computer, the code if the only code means there a problem with the knock sensor, you will need to check the connection and make sure the wire is good and if it is then you will need to replace the knock sensor, heres a diagram to help you locate the knock sensor good luck, hope this helps,

The knock sensor is threaded into the block of the engine, just below where the cylinder head sits. You will need to remove the intake plenum (upper and lower) to access this part.

engine noisy,used one of them sunday mechanics code readers and reckon you know it all now ???only one cause of a noisy engine and thats because its been run with no oil,or had the guts thrashed out of it,or a pulley tensioner bearing run dry,clutch thrust bearing ,water pump,in fact anything .GET A PROFESSIONAL TO LISTEN,call a local mobile mechanic for an opinion then ask how to cure it on the cheap.

If The engine in your van is a 3.5L, the knock sensor is under the upper intake manifold. This has to be removed in order to access the sensor on top of the engine block. The job requires an upper intake gasket set and about 1.5 hours to do; if you are handy with tools. For those who aren't; better off leaving this one to the professionals.
