Faulty lambda? (031 + 032)

[fred80]

I've just been doing some logging and the first thing was block 032.

All runs were from about 2000 to 6500 in 3rd, engine is a BAM.

All the way down the first column was 0%.

Group A:	'032	
	Idle Value	Part Throttle Value
TIME		
STAMP	%	%
0	0	0.8
1.13	0	0.8
2.3	0	1.6
3.4	0	1.6
4.53	0	1.6
5.73	0	1.6
6.98	0	1.6
8.15	0	1.6
9.24	0	1.6
10.26	0	1.6
11.47	0	1.6
12.59	0	1.6
13.77	0	1.6
14.89	0	1.6
16.11	0	1.6

Does that mean the o2 sensor is duff?

Whats strange is block 31 is showing readings for air/fuel.

Group A:	'031	
	O2S1 Voltage	O2S2 Voltage
TIME		
STAMP		
0	0.969	0.906
0.58	0.875	0.86
1.13	0.844	0.844
1.72	0.828	0.836
2.34	0.828	0.836
2.98	0.836	0.836
3.51	0.828	0.836
4.02	0.836	0.836
4.53	0.828	0.836
5.11	0.828	0.836
5.64	0.828	0.836
6.23	0.867	0.836
6.73	0.828	0.836
7.23	0.828	0.836
7.75	0.821	0.836
8.39	0.836	0.836
9.01	0.836	0.836
9.53	0.828	0.836
10.05	0.828	0.836
10.55	0.836	0.836
11.07	0.821	0.836
11.59	0.828	0.836
12.19	0.828	0.836
12.77	0.828	0.836

Firstly do they look ok?

Secondly how is it measuring this if the sensor is indeed faulty?

Thanks for any help!

Sorry for the bump but I'm really confused with this.

One source says 0% all the way down on 032 is a duff sensor, others say its a long term value and could be fine

 

[fred80]

Last time bump.

I am actually that far out of ideas and have spent hours upon hours reading all manor of conflicting information on websites.

Looks good to me. There would be a problem if both fields were 0 and you haven't reset the error anytime recent.

0 for ADD trim and 1.6 for MULT trim is just great.

What problems do you have?

 

[DPJ]

Agreed. Nothing wrong with 0% additative trim.

Thank you so much for the replies, its VERY much appretiated.

There is no problem as such, I was just doing some logging on blocks I read in a 'to check' guide.

The guide made out as though 0 is a fault, it then got me wondering if its damaging the car etc etc

Thanks again for setting my mind at rest!
