Description
Fuel Temperature Sensor for 1.4 HDi 16V 66 kW 8HY Engines For Citroën And Peugeot Vehicles.
This fuel temperature sensor is designed for PSA 1.4 HDi 16V (66 kW, engine code 8HY) applications and is a direct-fit replacement for vehicles in the Citroën/Peugeot family such as Citroën C3 and Peugeot 1007. The sensor provides the engine control unit (ECU) with accurate fuel temperature data so that fuel injection timing, quantity and combustion calibration can be adjusted for optimal performance, emissions and fuel economy. Commonly searched by part numbers, this unit is listed under 9306-010A, 9306Z010 and 1920FH — include these codes in searches to quickly find the correct item.
Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: Engine: 1.4 HDi 16V 66 kW (8HY); Vehicles: Citroën C3, Peugeot 1007
- Product Codes: 9306-010A, 9306Z010
- Other Numbers: 1920FH
Functionally, the sensor is an electronic temperature sender that delivers a voltage/resistance signal to the ECU. The ECU uses this information together with other sensor inputs to refine injection quantity and ignition strategy. Accurate fuel temperature measurement helps reduce cold-start emissions, prevents incorrect fueling during long idling or high-load operation and supports correct diesel particulate filter (DPF) and regeneration behavior in modern diesel systems.
Recommended Installation
Intended for experienced technicians and competent DIYers. General replacement steps:
- Relieve fuel system pressure before starting work and disconnect the vehicle battery.
- Locate the sensor (typically fitted to the fuel rail or fuel line near the filter/fuel pump on PSA 1.4 HDi installations).
- Disconnect the electrical connector and remove the sensor (usually threaded into its boss).
- Install the new sensor with a new sealing ring/O‑ring, tighten to the manufacturer’s specification without over-torquing.
- Reconnect the electrical connector, reconnect the battery, prime the fuel system and check for leaks.
- Clear any stored fault codes with a diagnostic tool and verify correct sensor readings and engine behavior during a test drive.
Why This Part Fails
Fuel temperature sensors are durable but can fail or degrade for several reasons. The most common causes are:
- Contamination from dirty fuel, varnish or particulate deposits that alter sensor response.
- Water in the fuel causing corrosion or intermittent electrical faults.
- Connector corrosion, broken wires or poor contacts due to vibration and environmental exposure.
- Thermal cycling and age-related drift of the sensing element (thermistor), leading to inaccurate readings.
- Mechanical damage during servicing or from impact.
There is no fixed service interval for fuel temperature sensors; replacement is normally performed when diagnostic trouble codes point to incorrect temperature readings, when the engine exhibits fueling-related symptoms or whenever the sensor is damaged during maintenance.
This part is aimed at professional garages and skilled DIY mechanics who need a reliable, OEM-compatible fuel temperature sensor for PSA 1.4 HDi engines. Use the product codes above when searching to ensure correct fitment and quicker identification.
