Omega General Help / Re: Knock sensor, Trouble code 17

Quotedrove from Plymouth to Epsom this morning, EML light is on and off....Fault on knock sensor will retard that bank fully, hence run like a Fiesta.
can feel wheh the sensor is not pickiing up, it feels like a misfire, it is frequent enough to keep the light on for most of the journey.
I have a feeling this one will need replacing rather than constantly bodging the wiring but i can't for the life of me find it, does anyone know where it is and how to get to it, i have looked from the top and bottom and can see the square root of diddly
Jamie, you say it is co-ax, this one isn't, it is a twin core cable with one of them insulated and the other not
Bank 1 sensor is behind alternator, bank 2 up near engine mount. I think you have to remove mount to get to it iirc. Not sure if A/C will be in the way.
I think 17 is bank 2.
the wire goes down between the top hose and dipstick tube and then disappears into the bowels of the engine.
I'm running on LGP so limp mode wouldn't have an effect on the LPG ecu, but it would still retard other aspects of the engine that it has control over.
if i flick it over to petrol then it does run like it has 90bhp, back to LPG and it takes off again
I damaged the sensor wire many moons ago when i did the rocker covers for the first time, it has been soldered but i have a feeling that the wiring is brittle where it has been bared back and left open to the elements for a while.
Replacement is on the cards and i am not looking forward to it, this might be a job for the garage
