The Motorcraft DY1159 Air Charge Temperature Sensor measures the temperature of the air entering the intake tract and reports it to the engine control system, which uses the reading to trim fuel delivery and spark timing. A sensor that drifts or fails can lead to rough running, poor cold-start behavior, reduced fuel economy and stored trouble codes. This unit is built to OE form and function so it drops into the factory location and connects to the factory harness without modification.

Motorcraft DY1159 Air Charge Temperature Sensor Features:

• Reads intake air charge temperature and sends the signal the engine control system uses for fuel and spark calibration.
• Built to original equipment form, fit and function for a no-modification installation in the factory sensor location.
• Helps restore correct cold-start behavior, idle quality and fuel economy when the original sensor drifts or fails.
• Connects to the factory wiring harness with no splicing or adapters required.
• Sold individually.
