Title: 02 sensors for ME7.1 and ME7.1.1 Post by: BlackT on March 04, 2024, 08:00:32 AM I have put 02 sensors from ME7.1.1 on ME7.1
I can see 02 voltage and it looks normal, but fuel trims does not work. And I get error Oxygen (Lambda) Sensor B1 S1: No Activity Oxygen (Lambda) Sensor B2 S1: No Activity They have different 02 plug, but 02 sensors schoud be same or? Title: Re: 02 sensors for ME7.1 and ME7.1.1 Post by: IamwhoIam on March 05, 2024, 10:13:27 AM define "normal" voltage please? also, what kind of ME7.1.1 exactly?
Title: Re: 02 sensors for ME7.1 and ME7.1.1 Post by: prj on March 05, 2024, 10:31:02 AM Are you sure one isn't LSU4.2 and the other LSU4.9?
Title: Re: 02 sensors for ME7.1 and ME7.1.1 Post by: BlackT on March 05, 2024, 01:18:17 PM Sorry for lack of information, I forget that there is a so many variants od ME7.1.1
In my case I am talking about 2.7 TT engines ECU is ME7.1 AMX 2.8 N/A, and probes are from M7.1.1 BEL They are both narowband only they have different connector. When I say normal voltage that mean it folows what my external afr gauge show( when it is lean voltage is below 0.45 V goes to 0.1V and when it is rich it goes to 0.9. It show normal voltage depend how engine work like any other narowband probe Title: Re: 02 sensors for ME7.1 and ME7.1.1 Post by: prj on March 06, 2024, 04:36:12 AM There are many different types of narrowband sensors.
Buy the correct ones for your engine and don't waste time. |
