Hi guy's, can anyone please tell me if the fault codes P0195-00 & P250A-92 would cause the motor not to start?

It's a 2001 4.4TDV8 with 109k miles on it.

Many thanks

Ash

Have you looked them up in the workshop manual ? Gone to a good home: 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"
2025MY Defender D350 90 in Silicon Silver on coils
1974 Series 3 Lightweight = "Millie"
Many, many other Landies over the years

No Mate, I haven't got a workshop manual

It’s in the Wiki on here

Thanks, ive just had a look & can't see where it would tell me

There’s a DTC section in the manual. Lists them all out  Gone to a good home: 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"

Just google the codes if you can't find it on here. They are to do with the oil temperature/level sensor.
