Description
FAP exhaust manifold pressure difference sensor
For CITROEN PEUGEOT
cars
FAP pressure sensor (DPF differential pressure sensor) for Citroën/Peugeot cars with OEM number 9662143180. Used original part dismantled from a PSA car, suitable for checking the particulate filter (FAP/DPF) clogging according to the pressure difference before and after the filter. Thanks to the correct function of the sensor, the control unit can correctly trigger regenerations and keep the engine in optimal mode.
Key benefits
– Verified OEM designation: 9662143180 (PSA), also often searched under internal code 02169985
– Compatible with a range of Citroën and Peugeot models with FAP/DPF
– Correct replacement if your original part number and connector fit
Typical malfunctions when this part will help
– Fault codes related to FAP differential pressure (eg P2452, P2453)
– Emergency mode, failed DPF regenerations, performance fluctuations
– Deteriorated consumption and frequent illumination of the engine light
Technical information
– Function: measurement of the pressure difference before/after the FAP (DPF) to calculate fouling
– Design: electronic sensor with analog output
– Connector: 3pin PSA type
– Power supply: usually 5V (ECU controlled)
– Output: typically 0.5–4.5 V proportional to differential pressure
– Hose connection: 2 pressure ports (P1/P2) for small diameter hoses
– Mounting: mounting in the holder in the engine compartment (location varies by model)
Note: Specific parameters and mounting may vary depending on the variant. Always compare with the original work.
Compatibility
– Citroën: C3 Picasso, C4 II, C4 Picasso (and other PSA models with FAP/DPF)
– Peugeot: 307, 308 (and other PSA models with FAP/DPF)
The most reliable verification is that the OEM number 9662143180 and the connector/tubing connections match your original sensor.
Condition and contents of the package
– Used part – shows normal signs of use
– Supplied as a separate sensor without tubes and holders (unless stated otherwise)
– The condition corresponds to the product photos
Installation tips for trouble-free operation
– Check and, if necessary, replace the silicone tubes for the FAP – cracks or blockages will distort the measurement
– Clean the metal intakes on the exhaust manifold (they tend to have soot deposits)
– Clear fault codes after assembly and perform basic sensor setup/calibration in diagnostics if required
– Check the tightness of the joints and the placement of the hoses away from high temperature areas
How to verify the correctness of the part
– Compare OEM number: 9662143180 (PSA)
– Check the shape and orientation of the 3pin connector and the pair of pressure ports
– Verify sensor location on your specific engine and mount type
