It's on the A/C line that runs along the firewall. It is the sensor on the left side. You have to evacuate the system to replace it, then vacuum it down and recharge it.

Don't overlook the possibility the electrical connector is not making proper contact at the sensor.

Unlikely I know, but hope springs eternal . . .
