Hello all. My apologies if this has been asked before.

My octy 2.0 fsi petrol had intermittent problems of engine dying especially during uphills and reversing into parking. i plugged my vcds and found a code

16577/P0193 - Fuel Rail Pressure Sensor (G247): Short to Plus - Intermittent.

googling shows either the wiring or the sensor itself is at fault. the problem has been increasingly frequent lately, to the point that if the car is parked for more than 8 hours, a jump lead is needed as the battery would be drained (tested battery to be healthy, could it be the short that parasitically drain the battery?). visited golf mkv and audi forums and some said the fuel pump, clogged fuel filter could trigger this code as well.

 

now before I hit-and-pray (buy a new sensor and plonk it in praying that it would work), any ways that i can check things out to rule certain failures out? or is it really as straight forward as getting a new sensor?

Cheers,
Eddie
 

You have 3 wires on your pressure sensor

1) 5v live

2) ground

3) signal

Using a multimeter back probe the signal wire with the plug still attached to the sensor, are you getting 5v? If so this is why you are getting fault code......

Now disconnect the plug, does that turn to 0v or stay at 5v or something else?

Hi,

 

Sorry for bringing up an old post.

 

I have the exact same issue with mine.

 

I tested the wires and the results are below 

 

Wires -
1 (left wire, green/brown colour) - 0.01v
2 (middle wire, yellow/red colour) - 5.68v
3 (right wire, red/blue colour) - 5.02v
 

Does this indicate a fault with the wiring.

 

Many thanks
