4390 - Charge-air temperature sensor, signal - HELP! - eldaniel - 10-16-2023

Hi all!
Patient - E60 Lci 525d 145kw/197hp
I downloaded inpa and ista-d.
Everything works good. But I have an issue with error no.
4390 - Charge-air temperature sensor, signal.
Checked sensor / resistance - okay.
Checked plug cable contacts - no voltage when ignition on and ignition off.
Did somebody had similar problem and solved it?
Can somebody help me please? Maybe wiring diagram can help me too.
Thanks in advance.
Daniel

Use ista-d to check the issue. Test plan should be able to give you options to troubleshoot the issue and you can also view the wiring.
