PP2000 Faults - What do they mean?

[p1lyp]

Hi,

I've had a PP2000 clone bought from eBay for a while now but I've only just recently had the time to get it to talk to my car. It's doing so now but the 'Engine ECU' faults (all intermittent) are as follows and don't mean a lot to me. Can you help please:

Cylinder reference sensor. Engine speed sensor consistency (on starting);
Condensor 1 voltage. Internal fault in the ECU;
Diesel high pressure monitoring function. Lack of pressure (leak);
Circuit Additional heating 1 Open circuit or short circuit to earth;
Circuit TL4226 fault. Faulty circuit.

Google suggests the first fault is the cam angle sensor and the last one is spurious - most HDis seem to have this fault without issue.

The car runs faultlessly but the EML stays on permanently which gnaws away at the perfectionist, enquiring part of my brain. It came on at the last turn of the engine with a dead battery last winter.

The car is a D9 90 HDi.

Clear them and see what reappears, it should narrow it down somewhat.
