  • Product Description

    DPF Differential Pressure Sensor (CJAA)
    manufacturer: OEM VW
    part number: 076906051B


    This is the part that reads the Differntial pressure (D/P) across the diesel particulate filter (DPF) in your common rail TDI. (see applicability below or contact us for compatibility). When it fails there may be a low power condition accompanied by a check engine light (CEL) and or flashing glow plug light. The DPF needs this signal to perfom a regeneration, and no regen means the soot builds up until a check engine light appears along with the one or both of the following diagnostic trouble codes:

    009315 - Diesel Particle Filter
    P2463 - 000 - Excessive Soot Accumulation - MIL ON

    009299 - Diesel Particle Filter; Differential Pressure Sensor
    P2453 - 001 - Implausible Signal

    The DPF warning light may also be lit along with the flashing glow plug lamp and check engine light.

    Replacing this part, followed by a service regen, fixes the problem indicated by the DTC indicated above.
