Unidiag P0150 and P0130
I just got these error codes in my car. 2.0ts 2001 147.
Now i know these are the two precat lambdas.
Funny thing is, the MCSF light is off and if I clear the errors and take a short drive, they re-appear.
Why is the MCSF light not on ? I know the bulb itself is ok, as I had it light up some time ago because of my MAF.
I find it odd that both lambdas have gone at the same time and gets me thinking the issue could be somewhere else.
The postcat lambda is ok i guess, reads ~1.00 all the time.
When starting the engine cold, the precat ones were reading chaotic figures, going from 90mV to 660mV
