Kamui Kobayashi is keen to repay his Sauber team after crashing out in qualifying for the Singapore GP.
The Japanese driver will start Sunday's grand prix at the Marina Bay circuit in 17th place as he failed to set a time in Q2.
Five minutes into the session, Kobayashi, who had been riding the kerbs hard throughout the earlier practice sessions, paid a heavy price when took too much kerb and landed nose first in the barriers.
The Sauber driver readily admits the accident was his own fault and has vowed to make amends come Sunday night's race.
"I ended up in the wall in Q2 and the accident was my fault. I feel very sorry for the team," he said.
"I took too much kerb in Turn 10, the car jumped too high and this was the outcome. I saw a chance to fight for Q3, but it didn't work out.
"I was taken to the medical centre and was quite surprised at how carefully they checked me. However, physically I'm absolutely fine.
"I will do my utmost tomorrow to fight for points and give something back to the team."
