DIESEL PARTS / SENSORS, ACTUATION AND CONTROL VALVES

# Diesel Temperature Sensors (EOT / ECT / Fuel)

Find oil, coolant or fuel temperature sensors for your diesel engine. Start with the correct EOT, ECT or fuel-temperature part number.

A sensor-related trouble code can have several causes. The original part number and engine application help our team narrow down an appropriate replacement inquiry.

## What this component controls or measures

Engine oil, coolant and fuel temperature sensors serve different control functions. Temperature readings should be interpreted for the correct circuit.

## Identify the correct Diesel Temperature Sensors

Provide the exact sensor marking, sensing location and engine configuration.

Give the sensor marking, connector style and location on the engine. If there is a diagnostic code, include the code and the observed symptom rather than using the code as the part identification.

## Replacement and diagnostic questions

Confirm connector, range and system use through correct part identification before replacement.

Check connection, mounting and test results before assuming a sensor or valve is the cause of a code or symptom. Sensor nomenclature can vary across engine families and is not proof of interchangeability.

## Diesel Temperature Sensors: numbers and identification

Related part names include engine oil temperature EOT, engine coolant temperature ECT, diesel fuel temp. Confirm the original number, connector and circuit before ordering.

## Ask DCT about Diesel Temperature Sensors

Include the exact part and controller number, engine application, fault history and verified electrical or connector findings. DCT can confirm current sourcing options for the correctly identified part; only published store listings establish checkout availability.
