No its right above the Thermostat housing you will see two sensors next to each other its going to be the Left one (A 2 lead sensor with a square plug)

See the red plug toward the frot right next to the timing chain tensioner?
Thats the one.


Check you ECU for codes also, it will save a lot of trouble shootin. CTS will be Code 13

Just got back from checking that and it didnt work, just makes the same back fire noise once in a while, iv been messing with the cas timing and wouldent it atleast start if it was close and i know im atleast alittle close.

Will Check for codes right now never done it before but iv read a few forums on it

well if it were the CTS you would have to replace it in order or it to fix it

Normally when the CTS is bad your engine will run rich and take 15 seconds of cranking to turn on after the engine is warm, but will start when cold
