Returning P0130 & P0150 errors

Some time ago MSCF light went on so I checked with Multicecuscan what is the source of problem. There were following errors stored in ECU: P0130, P0150, P0136 and P0141 so all concerning all three lambda probes. After that all three lambda sensors as same as MAF were replaced (with original new Bosch parts).

After replacing lambdas and MAF I cleared all errors and did self-adaptation reset.

After more than 100 km I checked ECU again for the errors and found P0130 & P0150. Interesting thing is that mentioned errors do not light up MSCF engine light There is also no evidence in engine behavior showing that those two errors appeared.

Problem concerns 2003 147 1.6 TS 120 HP with 218 000 km / 136 250 miles on the clock.

This was the first time since new I replaced lambdas and MAF. Right now I really lost track of what else could be replaced to have ECU free from errors? Or if everything is working I shouldn't carry that much?

googled for P0150

«Water or corrosion in the connector
Loose terminals in the connector
Wiring burnt on exhaust components
Open or short in the wiring due to rubbing on engine components
Holes in exhaust allowing unmetered oxygen into exhaust system
Unmetered vacuum leak at the engine
Bad o2 sensor
Bad PCM»

since you got all lambdas and MAF replaced, I would check for bad connections and then check for air leaks in the intake after the MAF and in the exhaust...
