Check Engine light of doom

[Smizer]

My car is giving me cel and codes p0606 and p0171.  I have used TORQUE with elm 327 and i logged these faults with it.

Is this meaning that my lambda is ruined ? Yesterday i removed MAP-sensor and cleaned it with no difference. Car is consumpting lots of fuel and i think it lacks power. Engine  is MPI 1.4 petrol. Year 2001.   Is it possible that faulty lambda causes p0606 because of failed fuel / air mixture that ECU cannot understand ?

Before you go spending loads of money, check all the fuses that control the engine electrics.

 

You could also try disconnecting the battery, leave the car overnight, reconnect, erase the faults and see if they come back.

Thank you for your fast response and advice, but i have tried those options. When i clear all the fault codes they stay away until the car is started. It always shows the p0606 code when the cel turns on and pending code p0171. Thats why i think they are somehow connected together.

p0606 is engine control module fault. http://wiki.ross-tech.com/wiki/index.php/16990/P0606/001542

I've heard that this fault can be caused by a poor battery. Is yours OK?

Yea, i read that too somewhere and changed the battery to brand new. Today i removed lambda sensor and it looked bad. I couldnt yet get new one from local parts dealer. They had bosch version for skoda octavia 1.6 petrol engine, wirings and plug looked the same that fabia has, does it fit ? It had 5 wires when others that they were selling had only 4 wires. The price was terrible 140€ so i didn't buy it yet because i wasn't sure that it will fit. It was the first lambda.
