Hi there, I'm new to all this. So please bear with me.
I own a punto MK2 1242 8v , it's been unused and on my drive for about a year now. I've replaced the tired engine. On starting her up I noticed the check engine light was on. I plugged in my code reader and PO141 came up. Thinking the lambda sensor was at fault I replaced it. But the code kept reappearing.
Only 3.37volts is coming to the lambda sensor when it's supposed to be 12volts.Even when the fuse is removed , it's showing 1.2volts !!?
Can anyone help me please.
