Charge Temperature Switch (Cts) 6-Cylinder And V8 Models
Switch is installed in No. 6 runner of intake manifold on 6-cylinder engines and in No. 8 runner of intake manifold on V8 engines. When air/fuel mixture temperature is below 60°F, switch closes, preventing EGR timer and EGR valve operation. Above 60°F, switch opens, allowing EGR timer and EGR valve operation.
