Knock sensor signal fault 5 Months ago Karma: 1
Hi guys hope someone can help me
Have 92 rev2 turbo and keep getting code 52
Sensor is good, wires seems to be good as I checked the continuity
And I don’t think Ecu is bad
Basically when I start the engine and rev over
3000 revs the engine light shows up and also
I can hear the turbo spoiling and gage is working but don’t have the kick
Out of the turbo so I’m assuming it’s rekated but not dure

This can sometimes happen when you buy dodgy petrol. It happened to me once and I then topped it up with a good known supplier and drove easy for the next few hundred miles until the bad stuff had passed through.

Is the engine hesitating/spluttering at all ?

Hi thanks for reply the engine is running ok just very rich and in limb mode
As you know in Ireland you can’t buy super unleaded so I’m using fuel from
Maxol only and never had problems with other cars
This one I bought as a non runner and when I finally got her fixed up she throws that
52 code
