Default CEL again. Similar codes to last time but why would it disappear for .....

several weeks then re-appear?
Any ideas?

Address 01: Engine
Controller: 4B0 907 551 R
Component: 2.7l V6/5VT G 0001
Coding: 10712
Shop #: WSC 02325
WAUZZZ4BZ1N048536 AUZ7Z0Y1551952
3 Faults Found:
17867 - Exhaust Gas Temp Sensor 2 (G236): Implausible Signal
P1459 - 35-10 - - - Intermittent
17539 - Oxygen (Lambda) Sensor: B2 S1: Internal Resistance too High
P1131 - 35-10 - - - Intermittent
17521 - Oxygen (Lambda) Sensor: B1 S1: Internal Resistance too High
P1113 - 35-10 - - - Intermittent
Readiness: 0000 0000

I guess it could just be a loose connection to the EGT sensor which is causing the two Lambda problems because the ECU is not picking up a sensible exhast gas temp?

I will have a look at it this weekend I hope, providing I get time.
