Getting High

If the AOS is replaced it will take some running to clean the oil from everything.

Hi Guys,

Ok update and more help needed

I have been lent very kindly by a good chap, a diagnosics kit, I have read the following faults in the memory since giving it a good drive.

P0150 - O2 Sensor ahead of cat conv (cyl 4-6)

P0300 - Misfiring damanging to cat.

P0306 - Cyl 6 misfiring damaging to cat

P1119 - Heating power O2S ahead of cat. bank 2

I then analysied the misfire read outs, and cylinder 6 was misfiring quite heavily, while Cylinders 1 and 5 misfired once (over a period of around a 5 minute drive)

I then read the voltage of the O2 sensors over a 72 second period

On Bank 1, the lowest voltage was 0.07 and the highest was 0.82. The values were shooting up and down at every samples rate

On Bank 2, the lowest voltage was 0.13 and the highest was 0.24. The values stayed quite steady with every sample rate

What are your immediate thoughts??

Many thanks

O2 sensors voltage have to fluctuate, if they don't change out the sensor. Replacing all the coils is the best option.

I actually brought a full new set of coils only early last year.........could they have gone that quickly??

Cheers

One year is indeed pretty quick, you have to take a look. Are the codes and the values read by PIWIS?

they are read by durametic
