Few fault codes, any ideas?

[MaxiSNK]

Been having a few problems with my ETM light coming on lately and engine management, seems totally randomly it happens comes and goes!

its been into a garage today and came back with these codes.


P1600
P1603
P1608

Also came back with low voltage pin 12

any ideas would be much appreciated.

P1600 - Throttle unit internal fault, faulty signal
P1603 - Throttle unit internal fault, faulty signal
P1608 - Throttle unit internal fault, signal missing, signal too low

Looks like you need to get your ETM sorted, there are a few threads on here which cover this.

Hope this helps
