thats what my engine light reads,im desperate to find out how serious this is.it could be the wiring or might be the whole tdc sensor,which is a dealer part.anyone have any idea,i loose all my push when the engine light comes on,but it doesnt happen all the time,and idle is funny sometimes.

 

You either have a bad sensor or there is magnetic interference near the sensor that is causing the error. Did you do anything to your car recently and does it happen intermittenly?

 

this has been going on for a while now,ussaully when im driving slow through the city,in ildle most of the time it comes on,but its very hard to narrow it down as to when it the engine light comes on.they said at the dealership on the phone that its probably the tdc sensor(kit)that includes a few different parts that hav eto do with the crankshaft psoition sensor,"THEY THINK".but it might be the wires.

 

Did you guys ever find out what the problem was with your Vig Jessesvig? I am going through the very same turmoil. Any info is greatly appreciated. Thanks

 

just replace it already

 

Crank Position Sensor is pretty common to go out on the Vig. Test resistance of the Crankshaft, Camshaft and TDC sensors with a multimeter to know for sure. They should all be 650 to 850ohms.

These three sensors play a HUGE part in fuel and ignition timing. If one of them fails (99% chance Crankshaft in your case), the ECM goes into "limp home" mode, using a default fuel/timing map that is not intended for prolonged driving. It will also cut out around 3500RPM or so.

 

it has no tdc sensor

 

It does, it's just sorta "built in" to the Crankshaft Position Sensor.

You can see the two different sensor pickups in this pic:

 

It still has no TDC sensor, but I'll bite on this for a minute..
Do you know how this system works? How does it know when it's at TDC?
What's the system called?

 

While I don't know any "Acura tech" secrets about it, I know it's basically a magnetic inductance sensor setup, reading the "teeth" on the gear pictured above. Works alot like an ABS sensor.

Don't get the wrong idea...I'm not here to argue or match wits, I'm hear to learn mang! If you get a minute, I'd love to hear more about it and why/how it "has no TDC sensor."
