But Australia registered a five-wicket win in the fifth and final ODI at Adelaide to take the series as well as the number one position in the ODI rankings table.
India, who are trailing 0-2, need to win remaining two games against New Zealand to climb up the ladder again. The third ODI between India and New Zealand had ended in a tieon Saturday.
Australia started the series in second place with 114 ratings points, while England (111) were in third place.
At the conclusion of the series, Australia have earned three ratings points to finish atop the table with 117 ratings points, on par with India, but when ratings was calculated beyond the decimal point, Michael Clarke's men were ranked ahead of Mahendra Singh Dhoni's side.
England, on the other hand, have dropped two ratings points to finish on 109 in fourth place, one behind South Africa.
If India win both the matches it will go to the top with a gain of one ratings point to end at 118, one ahead of Australia.
But if it lose even one of the two matches, India will stay in second place with a loss of one ratings point at 116, one behind Australia. Loss in both the matches will mean India drop two ratings points to finish on 115 in second place, two behind Australia.
