Peugeot 207, 02 Sensor/Lambda Sensor Fault Code: P0138 & P0141 Diagnosis And Fix 

These Peugeots are Notorious for Head gasket failure around 80,000 Miles..! Maybe that is the Cause of The Engine warning Light..! I have one to sell Maybe you would be interested..?🤔🤔

Can’t be the head, scan returns code P0138 and P0141

Ok Replace both 02 Sensors then but Peugeot and Citroën Cars have a Leaking Head Gasket Fault. @@mzwakhegiftsimelane2680
