Faults Code 6.3, 4.3, 24.7

Hi

I have these faults code shows on nanocom: 4.3 coolant temperature circuit, 6.1 inlet air temperature circuit, 6.3 coolant temperature circuit, 27.7 problem detected with auto gearbox. Check harness at the ecu and only a little of oi but spray it anyway to clean, cleaned IAT and MAF. Now I still have fault codes 4.3, 6.3 and 24.7

Anyone has experienced this before? Anything else I need to check and cleaned or the coolant sensor is faulty. The drive normally except the vibration at 1800-2000rpm (on another thread) but this could be engine mounting need to be replaced. We will do them soon anyway.

Thanks
Gus

Did you clean the contacts on the water temperature sensor.
I once had my temp gauge reading low and a few on/offs of the connector fixed it.The ECU takes its water temp reading from it.
What about the boost/temperature sensor in the inlet manifold? If you have EGR still it could be gunged up.
No fault codes though.

Thanks philip.

No I haven’t cleaned the water sendor contact. I will do it soon.

Don’t have EGR but I did clean the sensor anyway.
