2023年1月28日 · A G505 differential pressure sensor fault indicates a problem with DPF and potentially the DOC. A blockage in DOC would result in an excessively low diff psi across dpf. A blockage across DPF would result in excessively high diff psi across dpf.

2017年6月8日 · My guess is that T3/3 is G505 input for ECU. T3/1 and T3/2 are described as 5V for pressure sensor. Have tried to make a test drive (with overrun). Then make a service regeneration with VCDS?

2015年5月28日 · The diesel particulate filter contamination status is calculated using these signals from the exhaust gas temperature sensors, together with the signals from; Exhaust Pressure Sensor 1 -G450-, Differential Pressure Sensor -G505-, Exhaust Pressure Sensor 2 -G451-, Mass Airflow Sensor -G70-, and Heated Oxygen Sensors.

2015年9月10日 · Is the G505 "differential pressure sensor" the "low pressure EGR differential pressure sensor"? I thought it was, but then VW's workshop manual states that the G505 is used to calculate DPF load. In seeming conflict, and true to VW form, VW's own self study guide 826803 states that G450 is used to calculate DPF load.

2013年2月3日 · Dealer successfully convinced VW that BOTH the G505 and G450 sensors were bad, even though they failed to remember I have VCDS and can generally diagnose these problems myself. They replaced the (properly working) G505 …

2 – Differential pressure sender G505; is installed depending on which emission standard the vehicle complies with. 3 – The NOx sender G295; is contained in the control unit for the NOx sender GX30 together with the control unit for the NOx sender J583

2022年12月24日 · The differential pressure sensor is called G505. If we search the B8 Q5 wiring diagrams (and component locations) document on cardiagn.com, we come to a picture on page "1304", where it seems to show it on the underside of the car, I'm guessing that's on the DEF tank next to the DEF pump?

2014年10月20日 · My 2010 Jetta's CEL came on with a P0470 and P2454 faults blaming the G450 sensor being shorted to ground. I the process of trouble shooting I discovered quite a bit of misinformation concerning the two pressure sensors associated with the DPF (G450/G451).

2016年10月17日 · I got fault code P2002. I think to change Differential Pressure Sensor. It is a VW touran tdi 2.0 from 2020. working with uds protocol. Can I adapt Differential Pressure Sensor with the method you wrote above ? Hope this helps.

2024年9月16日 · You have often DPF regen, you had faulty injectors and crack on DPF module (that can means very high exhaust temp), so damage (they melted more or less) to these G505/G450 is very probably.
