Detailed Description

The Standard Ignition TX98 engine coolant temperature sensor is designed to provide accurate coolant temperature readings for engine control and gauge strategy. Its thermistor response is built to tight tolerance standards, which helps the vehicle system receive a stable temperature signal. This part number is commonly used on applications such as the 2001-2010 Chrysler PT Cruiser, 2006-2010 Dodge Charger, 2001-2008 Chrysler Sebring, and 2005-2007 Jeep Grand Cherokee. The TX98 also cross-references Delphi TS10154 for the same application.

Standard Ignition manufactures this sensor with in-house process control from component selection through final assembly. That approach supports consistent fit and electrical performance across the listed vehicles, including Chrysler 300, Dodge Caravan, Dodge Ram 1500, and Mini Cooper applications where the correct coolant temperature input is required for proper engine operation.

Common Problems This Part Can Address

• Incorrect coolant temperature readings on the dash or scan tool
• Hard starting or rough running caused by inaccurate temperature input
• Cooling fan operation issues tied to faulty temperature signal data
• Check engine light concerns related to coolant temperature sensor faults
• Driveability problems after sensor contamination, age, or electrical failure

Installation Notes and Tips

Verify connector style, terminal count, and sensor location before installation. This TX98 uses a black connector on some applications, and one listed fitment note specifies the sensor location on the intake manifold for the 2009 Dodge Journey. Another listed note for 2007-2008 Mini Cooper applications places the sensor on the cylinder head and identifies it as an alternate number. Always confirm the vehicle’s original sensor configuration against the application listing before replacement.

For fitment reference, this part fits 2001-2010 Chrysler PT Cruiser, 2006-2010 Dodge Charger, 2001-2008 Chrysler Sebring, 2004-2007 Dodge Ram 1500, and 2005-2007 Jeep Grand Cherokee. It also fits 2007-2008 Mini Cooper, 2008 Dodge Nitro, and 2007 Jeep Wrangler among the listed applications.

Quality Assurance

Standard Ignition states that its coolant temperature sensors are 100% factory tested, and the brand controls manufacturing from componentry through finished product. That process supports consistent quality and dependable service performance for the TX98.
