Where is the coolant temp sensor for computer on a Ford F-350 with 7.3l turbo engine?

The coolant temperature sensor (CTS) for the computer on a Ford F-350 with a 7.3L Power Stroke turbo diesel engine is typically located on the passenger side of the engine block, near the thermostat housing. It's a single-wire sensor, and often has a one-wire connector.

However, there's a caveat: There might be *two* coolant temperature sensors. One is for the engine control module (ECM) – this is the one you're looking for – and the other might be for the gauge cluster. They can look similar but serve different purposes.

To be absolutely certain:

1. Consult your vehicle's repair manual: This is the most accurate way to identify the location.

2. Use a wiring diagram: Trace the wire from the sensor to the ECM. This will lead you to the correct sensor.

3. Look for a single-wire sensor: The ECM sensor typically only has one wire.

If you're unsure after checking these things, taking a picture of the area and asking a mechanic or posting it on a forum dedicated to Ford trucks (like Ford-trucks.com) might be helpful. Be sure to mention the year of your truck as the location *might* vary slightly depending on the model year.
