In the first half, the hosts were the better team and thought they had grabbed the lead in the 15th minute.
After a swift break, Podence blasted into an empty net, but Jimenez was offside in the build-up, so it was ruled out.
A close-range header was also saved by Dendoncker. Chelsea didn’t get going until the final 20 minutes, when Sa made a fantastic stop to deny Pulisic, but that was their finest chance.
Chelsea has now dropped another two points, putting them six points behind Manchester City, who have defeated Newcastle United 4-0.
They face Brentford in the EFL Cup next, as they try to get back on track.
Wolves are still in eighth place, and their next game is a week from today against Watford.
