As I understand the case, which I've not been following closely, the charge is "perverting the course of justice" and, while Pryce has accepted that she committed an offence, by accepting three speeding penalty points for former Energy Secretary Huhne, she denies the charge of "perverting the course of justice", using the archaic defence of marital coercion, which is open to wives forced to commit a crime by their husband.

So ..... no, she did NOT "plead not guilty to coersion".
