Engine System Fault - Help

05 August 2015 - 05:17 PM

This is a problem with my daughters car, a Focus Estate, 1.6 Diesel, 2007.

For many months the "Engine System Fault" has been coming and going resulting in "limp home" mode when it shows. Currently it is on all the time and I am trying to help.

Using a basic OBD device, the following faults are showing.

P0483 - Powertrain

Cooling Fan Rationality Check


P0405 - Powertrain

Exhaust Gas Recirculation Sensor "A" Circuit Low


P0335 - Powertrain

Crankshaft Position Sensor A Circuit


P0380 - Powewrtrain

Glow Plug/Heater Circuit "A"


Note we have previously tackled the Exhaust Gas Recirculation Fault by blanking off the device as recommended in other threads. Since this fault has been showing when the "engine system Fault" has not been present I do not believe it is the root problem.

Can anyone advise which of these other faults could cause the "engine system fault" problem or advise any other way forwards.

Many thanks in advance.

I am probably being very stupid, but have been unable to find any search options that I use on other forums.
