Code 22 for your specific vehicle is for the ECT(engine coolant temperature) sensor
Check resistance on the ect sensor.
At water temp of 68degrees resistance should be 2ohms and at 104 degrees resistance should be 1ohms and at 140 degrees resistance should be at 0.5 ohms. If not within specs, replace it. If ok, check for cut/chafed wiring harness.
