    G450 (076-906-051-A) output signal...0,5 Volt or 1 volts ??

    Hi

    First of all, Merry Christmas

    Short version:
    Does anyone know if G450 (076-906-051-A) output signal (pin 3) is 0,5 Volt or 1 volts when 0 PSI difference between P1 and P2?

    Long version:
    Car:
    SKODA FABIA II Combi (545) - 1.4 TDI (80Hk)
    Engine BMS

    Car history (what I know):
    1: New diesel particulate filter mounted at a Skoda garage.
    2: Car pass MOT.
    3: On the way home engine light comes on.
    4: Skoda garage tell that sealing flange sealing flange (on the gearbox side) and camshaft position sensor G40 must be replaced.
    5: I buy the car. (old owner buys a new car)
    6: 2 fault code are present P0471 and P3008
    7: P3008 errors are corrected (timing belt change)
    8: P0471 working on solution............

    I have this code:
    (I'm sorry it is in Danish)

    001137 - Udstødningstrykføler 1 (G450)
    P0471 - 000 - Urealistisk signal (Exhaust Pressure Sensor 1 (G450): Implausible Signal)
    Fryseramme:
    Fejl status : 01110000
    Fejlprioritet: 2
    Fejlhyppighed: 1
    Nulstiltæller: 255
    Tidsindikation: 0

    Fryseramme:
    Omdr.: 0 /min (RPM)
    Hastighed: 4.0 km/h (SPEED)
    (uden enhed): -145.35 (mbar Particle Filter Different. Pressure)
    (uden enhed): -76.50 (mbar Particle Filter Offset Different. Pressure)
    Masseflow: 0.01 g/s
    Temperatur: 6.0°C
    Temperatur: 11.7°C

    Readiness: 0 0 0 0 0


    When I back probes the connector I have Pin 1= 5 Volt, Pin 2 = 0 Volt (GND), Pin 3 0,5 Volt (Engine not running)
    After G450 adaptation:
    (067-03): -145.35 (mbar Particle Filter Different. Pressure)
    (067-04): -76.50 (mbar Particle Filter Offset Different. Pressure)


    When I simulate 1 Volt on Pin 3
    After G450 adaptation:
    (067-03): 0.0 (mbar Particle Filter Different. Pressure)
    (067-04): -2.55 (mbar Particle Filter Offset Different. Pressure)


    So is my G450 defective or do I have another problem?

    (I don't know how to upload pictures )

    Hi

    Yes you are quite right. I need to get an English version installed.
    I'll try if I can get an English "Auto-Scan" tomorrow.
    Until then hereby the Danish version.

    Isn't g450 mandatory to replace alongside with DPF?

    And they just fail...so check wires, then replace.

    Hi Golfi_vend

    I don't know ... but it has not been replaced
    Wires is OK.
    I do not want to replace parts that are not malfunction, I want to find the fault.

    It is foolish to not replace psi sensors when replacing a dpf.
    Additionally it would be wise to be sure problems are corrected that caused ash/soot pile up.

    Hi Jack@European_Parts

    I agree with the fault must correct before the car is used.
    I just wonder about all the information I can find saying that the sensor is from 0.5 to 4.5 volts.
    But it seems the my ECU expects not below 1 Volt
    So maybe I have bigger problems

    I agree with the fault must correct before the car is used.
    I just wonder about all the information I can find saying that the sensor is from 0.5 to 4.5 volts.
    But it seems the my ECU expects not below 1 Volt
    So maybe I have bigger problems
    DK, don't take any of this to the bank but .5 volts say on a rail pressure sensor would be 0 pressure or baro, then the range would be .5 up to 4.5 or 5 for max range.

    5 volts is a very common reference volt for ECM, but can vary maybe even 8, but again what does a good one look like. If under pressure it is moving off .5 volts it is responding but is that response accurate, we don't know?

    IMO, would for posterity record the Info, then replace and see if they are congruent with the old. If they are you have a valid back up part. If code in that sensor comes up then move to corrupted path way all the way to ECM.

    Again if this information read while static in a bay may be factual but under dynamic load (I.E. driving) may not if connectors or pathway to the ECM is corrupted.

    Not a big fan of replacing expensive sensors but woukd in this case, then explore from there, JMO, and like belly buttons we all have one.

    LARIMORE.
