Standard Motor Products TS642 Engine Cylinder Head Temperature Sensor

The Standard Motor Products TS642 is a direct-fit engine cylinder head temperature (CHT) sensor designed to restore accurate temperature monitoring to your vehicle's powertrain control system. The CHT sensor measures the thermal state of the cylinder head and relays that data to the PCM, which uses it to regulate fuel delivery, ignition timing, and cooling fan operation — all critical functions for protecting your engine from heat damage.

Engineered to OE specifications, this sensor is built with high-quality materials to ensure reliable signal output across the full operating temperature range of your engine. A precise and stable signal helps prevent rough idle, poor fuel economy, and potential engine damage caused by overheating or faulty temperature data.
