Hey guys, My Check engine light Is NOT on however I scanned it
to see anyway using my OBDII Scanner, and I got these two codes.

P0116 - Engine Coolant Temp.Circ Range/Performance

P0332 - Knock Sensor 2 Circ Low Input

From a lil researching I got what was above,

Could P0116 be caused by a bad Thermostat? I think mine needs to be
replaced, it is always at the cold unless I sit in traffic then It goes halfway...

The Knock sensor, where could I get this sensor and where is it located
on the car?

Thanks again guys!

 

I would replace the coolant temp sensor first. If that doesn't fix it the water pump is toast. When the pumps go out they will cause a knock, which is what the knock sensor is picking up, knock sensor don't usually go bad.
If the CTS doesn't fix it, replace both the water pump and thermostat while you're in there. If you need a timing belt, it would be best to knock it all out at once.

 

Everything, timing belt etc... got replaced already and im only at 103,xx miles.

 

Well if you already replaced the water pump and thermostat........change the CTS sensor.

 

I didnt, Last owner said it got done. But carfax didnt show it.

Anyway, I'm going to replace that sensor first.

I found two, http://www.mjmautohaus.com/catalog/i...6188_6726_8984
Blue or Green one? Ones 10bux and ones 25. I don't know which I need.

Thanks!

 

So, No one knows which of the two I need?

Thanks!

 

I can tell you which you need if you let me know what car you have

Are the codes you got present or present/intermittent? If not, erase them and see if they come back. They could be old, healing fault codes.
