Introduction: Replacing an Engine Coolant Temperature (ECT) Sensor (Honda Civic 1999 D15B).

Picture of Replacing an Engine Coolant Temperature (ECT) Sensor (Honda Civic 1999 D15B).

Although my ect sensor is working fine, it has been in service since 1999. I decided to be proactive and replace the sensor. Luckily years ago I bought two of these by mistake and had them in storage ever since.

Read on for my sensor replacement job!

Step 1: Remove the Old Sensor.

Using a 19mm deep socket I removed the oem sensor. Coolant of course came out. I quickly screwed in the new one. There is no need for coolant air bleeding in this job.

Step 2: Install the New Sensor.

I used my digital Torque tool to make sure I installed it properly without damaging it. The Honda manual calls for 24 Nm.

Now my trusty civic is working fine and I'm happy.
