Seamer Ollie Robinson took six wickets for Sussex, but Warwickshire's bowlers struck back on the first day at Hove.
Robinson's career-best 6-33 removed six of the top seven as the visitors collapsed to 100-7 after just 32 overs.
Only Jonathan Trott (35) provided any resistance, while Steve Magoffin took three wickets to end the innings.
After Chris Nash and Ed Joyce fell cheaply, Luke Wells made an unbeaten 73, but three late wickets for Jeetan Patel left Sussex 140-5 at stumps.
Warwickshire, unbeaten in the County Championship this season, started well as openers Varun Chopra and Ian Westwood saw off the new ball.
But Robinson struck twice in one over as Westwood was caught mistiming a pull and Chopra edged to Jordan in the slips three balls later.
Ateeq Javid nicked behind, before Robinson removed Laurie Evans and Tim Ambrose in successive balls to bring up his first five-wicket haul.

Rikki Clarke and Trott fell shortly after lunch, as Magoffin ensured the visitors did not pick up a single batting bonus point.
Patel's three wickets gave Warwickshire hope of a positive result, but Wells's half-century left Sussex only 40 runs behind at the close of play.
Sussex bowler Ollie Robinson:
"When I first got here, me and (bowling coach) Jon Lewis tweaked a few things in my run-up and with my action.
"But I just try and do the basics well in training; hit a good length, a little bit of swing, a little bit of nibble.
"On a wicket like this, if you hit a good area you normally get a few wickets.
"It was just my day. It could easily have been Chris Jordan's day. He bowled outstandingly."
Warwickshire wicketkeeper Tim Ambrose:
"It looks like a result game. It is who can pinch the most runs before they get out.
"The wicket looks like it is not going to get a lot better.
"We thought we would get first use and see what it does later in the game."
