Airtex 5S15299 Engine Cylinder Head Temperature Sensor CHT Sensor

The Airtex 5S15299 is an engine cylinder head temperature (CHT) sensor, also called a cylinder head temp sensor. It measures the temperature of the cylinder head and sends that reading to the engine control module. The module uses the data to help calculate timing and fuel ratio.

Key Features:

• Engine cylinder head temperature sensor from Airtex Automotive Division, part number 5S15299
• Reports cylinder head temperature to the engine computer so it can make timing and fuel adjustments
• Works alongside the coolant temperature sensor and other engine sensors to help protect the engine and maintain performance
• Cross-references to Ford D2BZ6G004A, Echlin TS5631, BWD WT5080, Duralast TXSA48 and Standard Ignition TX322

A worn or failing cylinder head temperature sensor can cause inaccurate temperature readings. Symptoms can include reduced fuel economy, lower power, hard starts or a Check Engine light. Replacing the sensor helps restore accurate engine temperature data.
