How do get to the CTS on the vehicle listed above (SLE)? I see all the bolts to the plastic housing intake. Can these just be loosened and remove intake to get the sensor out? Afraid of breaking clip also. The sensor is visible just cannot access it as is. Is there a secret to doing this. If the plugin was off, it looks as if I could get a swivel on it to remove. Is this feasable? Hand just will not fit into space.

By CTS I suspect you meant the coolant temperature sensor?

If that is the case, the manual says you need to remove the inlet pipe and housing to get access to it.

Below you will find the process from the manual that will give this detail. Please take a look at this and let us know if you have other questions. Thanks
