Emission Control Sensor

Engine Cylinder Header Temperature Sensor

The Engine Cylinder Head Temperature Sensor detects the coolant temperature within the engine. The sensor then relays this information to the vehicle’s computer where it may make adjustments to the fuel injection, ignition timing or electric cooling fan.

Wells Engine Cylinder Head Temperature Sensors are designed to meet or exceed OE specifications for fit, form and function and come with hardware, thread sealant and other items needed for installation.

The sensor is located in the cylinder head.

If a vehicle displays one or more of the following symptoms, it may need a new Engine Cylinder Head Temperature Sensor:

  • Rough engine idle
  • Hard starting
  • Engine misfire
  • Decreased fuel economy
  • Check engine light is illuminated
