Fault Code ECN 190158

I have just done the pedal test on my 1.9 CDTi Zafira after the engine warning light (car with spanner) came on

I am getting two error codes:
ECN 050074 and
ECN 190158

From Google searches I am asuming the 050074 code is somethng to do with a speed sensor / ABS however I cannot find any info on 190158

Anyone got any nidea what error code ECN 190158 represents?
