Common Issues This Part May Address

• Incorrect coolant temperature readings
• Illuminated engine warning light related to temperature sensor input
• Rough cold-start or warm-up behavior caused by faulty temperature data
• Fuel mixture or idle control issues tied to inaccurate coolant temperature signals
• Cooling system monitoring faults on Subaru Legacy and Subaru Outback models

Installation Notes and Tips

Verify connector shape, terminal count, and sensor location before installation. Inspect the mating connector for corrosion, bent terminals, or heat damage, and confirm the cooling system is at a safe temperature before removing the old sensor. Because no wiring harness is included, reuse the existing vehicle connector if it is in serviceable condition.
