The engine controller leans on coolant temperature for fuel trim, spark timing, fan operation and cold start enrichment, so a lazy or out of range sensor causes symptoms that look like much bigger problems. Rough cold running, poor fuel economy, fans that never come on and a check engine light for the coolant circuit all trace back here. This is the genuine Mopar sensor for the application.

• Reports engine coolant temperature to the powertrain control module.
• Brass body built to Mopar OEM specifications for accurate readings.
• Broad application coverage across select Chrysler, Dodge, Jeep, Ram and Fiat models.
