Thermistor Engine Water Temperature Sensor 1338A7 Peugeot 96368024 96368023 9628454680 9636777180

Water Temperature Sensor 96368024/96368023/9628454680/1338.88/8942202020/9636777180/1338A7

As an NTC (Negative Temperature Coefficient) thermistor-type sensor, the 96368024 exhibits the following resistance behavior:

• Low coolant temperature → High resistance → High voltage signal to ECU
• High coolant temperature → Low resistance → Low voltage signal to ECU

The ECU interprets these voltage variations to determine engine operating temperature and makes corresponding adjustments to fuel delivery, ignition timing, and cooling fan operation.

The Water Temperature Sensor (Part No. 96368024) is widely recognized across multiple manufacturer platforms and corresponds to the following reference information:

This sensor meets automotive industry safety and performance standards, guaranteeing reliability equivalent to original equipment. It is backed by rigorous testing for longevity and precision.

The 96368024 water temperature sensor is designed for compatibility with a wide range of vehicle applications across multiple manufacturers.

Fitting Position: Lower

Important: Always verify thread size (M12 x 1.5), connector type (2-pin, oval/rectangular), and vehicle compatibility with your specific application before purchase.

A failing or faulty water temperature sensor can manifest through various drivability and performance issues. Early recognition of these symptoms can prevent more serious engine damage and costly repairs.

Incorrect temperature readings can impair the ECU's ability to enrich the air-fuel mixture during cold starts. This may result in difficulty starting the engine when cold, extended cranking times, or engine stalling shortly after starting.

When the sensor provides inaccurate temperature data, the ECU may incorrectly adjust fuel delivery, often resulting in a richer-than-necessary air-fuel mixture. This condition leads to noticeably reduced fuel economy.

If the sensor fails to detect rising coolant temperatures accurately, the ECU may not activate the cooling fan at the appropriate time. This can lead to engine overheating — one of the most serious consequences of sensor failure.

A faulty sensor can cause the ECU to maintain an elevated idle speed as part of its default or "limp-home" strategy. The engine may idle at higher RPMs than normal, even after reaching operating temperature.

Inaccurate temperature data can disrupt the ECU's calculations for ignition timing and fuel delivery, resulting in reduced engine power, rough idling, or hesitation and surging during acceleration.

One of the most common indicators of a faulty sensor is the illumination of the Check Engine Light on the dashboard. The ECU detects abnormal resistance values or signal patterns from the sensor and stores corresponding Diagnostic Trouble Codes (DTCs).

A faulty sensor may cause the temperature gauge to go to full hot or remain stuck at a cold reading, failing to accurately reflect the engine's operating temperature.

A faulty sensor can cause elevated CO values and interference with the lambda (oxygen sensor) control loop, potentially causing the vehicle to fail emissions testing.

Visual inspection may reveal:

• Cracks in the sensor housing
• Coolant leaks around the sensor mounting area
• Corrosion on electrical connectors
• Damaged or frayed wiring

A malfunctioning sensor can cause the engine to run too rich or too lean, leading to erratic idling or stalling.

When purchasing a replacement water temperature sensor (Part No. 96368024), the following factors should be carefully evaluated to ensure proper fitment, reliable performance, and long service life.

Before purchasing, confirm that the sensor's thread size (M12 x 1.5) matches your vehicle's cylinder head or engine block mounting point. Additionally, verify that the electrical connector type matches your vehicle's wiring harness — this sensor features a 2-pin connector with an oval or rectangular shape. Connector mismatch is one of the most common installation issues encountered during replacement.

While the 96368024 sensor is compatible with a wide range of vehicles — including CITROËN, PEUGEOT,  FIAT, and TOYOTA models — always cross-reference with your vehicle's specific year, make, model, and engine displacement. Key specifications to verify include:

• Vehicle manufacturer and model
• Production year
• Engine code (e.g., TU3A, DW8B, EB2)
• Engine displacement

Opt for sensors manufactured with high-quality materials that offer superior resistance to thermal degradation and coolant corrosion. A well-constructed sensor provides:

• Enhanced resistance to thermal degradation
• Superior protection against coolant corrosion
• Longer operational lifespan
• Secure electrical connection to minimize failure risk

Look for parts that meet OEM specifications for reliability and accuracy, as inaccurate readings can lead to engine overheating or poor performance.

The part number 96368024 (also written as 96.368.024 or 96 368 024) is an Original Equipment number associated with multiple automotive manufacturers. When purchasing, ensure the sensor displays the correct OE number and associated reference numbers (such as 133888, 1338A7, 9670340380) to guarantee proper specification.

When replacing a faulty water temperature sensor, it is advisable to inspect related cooling system components:

• Upper and lower coolant hoses for cracks, leaks, or deterioration
• Radiator for cracks, leaks, or damage
• Radiator cap for proper sealing
• Coolant level and condition
• Cooling fan operation

Always refer to the vehicle owner's manual for the correct coolant type and replacement procedure.

Before installing the new sensor:

• Inspect the wiring harness connector for corrosion, damage, or loose pins
• Check for broken or frayed wires
• Clean connector terminals if necessary
• Ensure a secure, weather-tight connection upon installation

While the symptoms listed above can indicate a faulty water temperature sensor, many of these symptoms can also be caused by other issues such as:

• Faulty coolant thermostat
• Wiring harness problems
• ECU issues
• Cooling system leaks
• Cooling fan motor failure

It is recommended to have the vehicle properly diagnosed using a scan tool to read stored DTCs before replacing the sensor. This ensures that the sensor is indeed the root cause of the symptoms and prevents unnecessary parts replacement.

• Allow the engine to cool completely before attempting sensor removal or installation to prevent burns from hot coolant
• The sensor comes with gaskets/seals — ensure they are properly seated
• Use a 19 mm spanner for installation and removal
• Tighten the sensor to the manufacturer's specified torque value (avoid over-tightening, which can damage the sensor or the mounting point)
• After installation, check coolant level and top up if necessary
• Start the engine and check for leaks around the sensor mounting area
• Verify that the temperature gauge operates correctly and the Check Engine Light (if illuminated) has been cleared

If the sensor is not installed immediately, store it in a cool, dry environment away from direct sunlight and moisture. Avoid dropping or subjecting the sensor to mechanical shock, as this can damage the internal sensing element.

When purchasing from a supplier, review the warranty coverage and return policy. Quality sensors should be backed by appropriate warranty protection against manufacturing defects. Keep the original packaging and proof of purchase for warranty claims if needed.

The water temperature sensor contains an NTC (Negative Temperature Coefficient) thermistor sensing element that exhibits a predictable decrease in electrical resistance as temperature increases. Installed in the engine coolant circuit, the sensor makes direct contact with the engine coolant to accurately measure temperature.

The ECU supplies a reference voltage to the sensor. As the sensor resistance changes with temperature, the voltage signal varies proportionally:

• Low coolant temperature → High resistance → High voltage signal to ECU
• High coolant temperature → Low resistance → Low voltage signal to ECU

The ECU converts this voltage signal into a temperature reading and uses it for critical engine management calculations, including fuel delivery, ignition timing, and cooling fan operation.

• Condensation damage – Moisture ingress can cause internal corrosion
• Electrical connection failure – Corroded or loose connector pins
• Internal thermistor failure – Open or short circuit conditions
• Physical damage – Cracks from thermal stress or mechanical impact
