Peugeot 405 GLI - Fuel consumption

Post by mircea » 25 Jan 2003, 02:42

Hello, my car (P405, 1.6L monopoint injection, 1992, 150 000km) takes about 8.5L extra-urban since a few months. Before everything was normal: about 6L. I suspect sensors problem (maybe lambda). No other evident cause. Oil consumption is normal.
Any idea about my problem? It is necessary (considering 11 years car age) to change lambda sensor or catalytic converter?
Thank you.
